  • Nonimmunoglobulin Crystal-Storing Histiocytosis (CSH): Case Report and
           Literature Review

    • Abstract: Crystal-storing histiocytosis (CSH) is an uncommon condition in which histiocytes accumulate a crystalline matter within their cytoplasm. Generally, those crystals are composed of either monoclonal or polyclonal immunoglobulin chains, which have a strong association with an underlying lymphoproliferative or plasma cell disorder (LP-PCD). Rarely, CSH has been reported as local or generalized manifestation of a variety of benign disorders. These cases are associated with crystals composed of nonimmunoglobulin substances. We are reporting an exceptional case of a local colonic CSH with Charcot–Leyden crystals. This patient underwent a screening colonoscopy that detected some polyps. The biopsy reported tubular adenomas, with a markedly dense, transmural inflammatory infiltrates, which were predominantly composed of eosinophils and crystal-storing histiocytes containing Charcot–Leyden crystals. The patient had a negative workup for LP-PCD and autoimmune conditions, including a normal skeletal survey and bone marrow aspirate/biopsy. The only positive laboratory workup was an elevated absolute eosinophil count and a positive IgG anti-Strongyloides antibody. Giving those findings, this parasitic infection is the most likely etiology of the CSH in our patient. Although there was an initial negative evaluation for LP-PCD, close monitoring of patients with either immunoglobulin or nonimmunoglobulin CSH is recommended.

  • Combination of Dabrafenib and Trametinib for the Treatment of Relapsed and
           Refractory Multiple Myeloma Harboring BRAF V600E Mutation

    • Abstract: Multiple myeloma (MM) is an incurable plasma cell neoplasia characterized by relapsed and/or refractory (R/R) disease course, which poses a major therapeutic challenge. New therapies, including BRAF V600E mutation targeting, may become a new treatment option for R/R MM. In combination with mitogen-activated protein kinase inhibitors (MEKi), BRAF inhibitors (BRAFi) could provide better tailored clinical management, although experience in this field is lacking. To this date, there is only one case describing R/R MM treatment with BRAFi vemurafenib and MEKi cobimetinib. This is the first case presenting a R/R MM patient treated with BRAFi dabrafenib and MEKi trametinib.

  • IgA Monoclonal Gammopathy of Undetermined Significance and Complication of
           Streptococcus mitis Bacteremia

    • Abstract: This case presents a patient with bacteremia of an unusual organism with a history of monoclonal gammopathy of undetermined significance (MGUS). MGUS is typically thought to be asymptomatic until potential progression of the disease. This case reports a patient with a history of MGUS who does not show disease progression, however, may be showing symptoms, such as immunodeficiency. This case displays bacteremia with Streptococcus mitis within a two-week period of an invasive procedure. Recent studies parallel this case by showing MGUS patients may have two times the risk of infections compared to the unaffected population. This report brings up the question of taking prophylactic measures for this patient population to prevent future complications.

  • Venetoclax and Decitabine for T/Myeloid Mixed-Phenotype Acute Leukemia Not
           Otherwise Specified (MPAL NOS)

    • Abstract: T/myeloid mixed-phenotype acute leukemia not otherwise specified (MPAL NOS) is an uncommon and aggressive leukemia without well-established treatment guidelines, particularly when relapsed. Venetoclax plus a hypomethylating agent offers a promising option in this situation since studies support its use in both acute myeloid and, albeit with fewer data to date, acute T-cell-lymphoblastic leukemias. We report the successful eradication of T/myeloid MPAL NOS relapsed after allogeneic stem cell transplant with venetoclax plus decitabine. A consolidative allogeneic stem cell transplant from a second donor was subsequently performed, and the patient remained without evidence of disease more than one year later. Further investigation is indicated to evaluate venetoclax combined with hypomethylating agents and/or other therapies for the management of T/myeloid MPAL NOS.

  • Diagnosis Dilemma of Angioimmunoblastic T-Cell Lymphoma in Tuberculosis
           Endemic Region

    • Abstract: Angioimmunoblastic T-cell lymphoma (AITL) is a rare hematologic malignancy recognized in the WHO 2016 classification as a clinical and histological entity. It is a very poorly described disease in Africa due to its rarity and diagnostic difficulties, particularly differential diagnosis with tuberculosis. Here, we report a 57-year-old man who presented with fever, weight loss, and lymphadenopathies. The diagnosis of tuberculosis was carried out based on lymph node fine needle aspiration showing the image of tuberculous adenitis and CT images in favor of necrotic lymphadenopathies. The presence of autoantibodies and the failure of tuberculosis treatment led us to perform a biopsy with immunostaining that confirmed pathological features of AITL. The patient was treated by CHOP-based chemotherapy, and complete remission was achieved. This case highlights the difficulty of recognizing AITL and the importance of considering other potential differential diagnoses of tuberculosis in the endemic region.

  • Sevoflurane-Induced Thrombocytopenia in Post-Robotic-Assisted
           Paraesophageal Hernia Repair

    • Abstract: Background. Transient transaminitis is an expected outcome from liver retraction after foregut surgeries. However, severe thrombocytopenia is usually not a sequela of that. We present a case in which sevoflurane is suspected of inducing thrombocytopenia as it was the only newly introduced medication to the patient during the hospital course. Thrombocytopenia may present in a variety of settings in hospitalized patients. However, managing this occurrence requires deep exploration of pathophysiology that can cause decreased platelets, which may be a challenging task in certain circumstances. The liver plays an important role in thrombopoiesis by releasing megakaryocyte growth factors. Therefore, liver dysfunction can present as thrombocytopenia or other platelet dysfunctions. Objective. To describe a presentation of thrombocytopenia possibly associated with anesthesia-induced transaminitis after a robotic paraesophageal hernia repair with mesh and fundoplasty with intraoperative esophagogastroduodenoscopy (EGD). Methods. A 55-year-old presented to the ED with abdominal pain and was found to have a large type IV paraesophageal hernia that was surgically treated with a robotic paraesophageal hernia repair with mesh. However, on the first postoperative day (POD) (#1), the patient developed new onset thrombocytopenia with transaminitis. Workup for thrombocytopenia failed to determine an etiology. With platelet transfusion, platelet count showed an upward trend. The patient was then evaluated and cleared for discharge by POD#5. Results. The patient’s POD#1 daily labs showed elevated values for liver function tests and a low platelet count of 10,000 platelets per microliter with an international normalized value (INR) of 1.3. She had received two doses of intravenous acetaminophen just prior to surgery. Her platelet count responded to two units of platelets but decreased again immediately after. She continued to have transaminitis with down-trending liver enzymes. Peripheral smear on review showed no evidence of schistocytes. A heparin-induced thrombocytopenia (HIT) screening was negative. The patient was regularly evaluated, and the platelets stabilized and slowly started to trend up. The patient recovered by the morning of her POD#5 and was cleared for discharge. Conclusion. We are reporting on a case of acute postoperative thrombocytopenia that was associated with transaminitis and elevated liver enzymes. We are linking the role of the liver dysfunction in noncirrhotic patients with surgical abdominal procedures. Although liver retraction transaminitis possibly played a role in the laboratory findings in the patient, the acute drop in her platelet count could be closely related to the use of sevoflurane anesthetic considering its potential hepatotoxic side effects. We also cannot rule out the sevoflurane directly affecting the platelet count.

  • Cerebral Venous Thrombosis in the Setting of Malignancy: Case Report and
           Review of the Literature

    • Abstract: Cerebral venous thrombosis (CVT) is a rare condition that can be difficult to diagnose due to its vague and nonspecific symptoms. It is even more unusual to identify CVT in association with malignancy. Given the rarity of this disease, treatment and management of CVT in the setting of malignancy is not well defined. This case report and review of the literature addresses the epidemiology, pathophysiology, and medical treatment for malignancy-related CVT.

  • Acute Laryngeal Dyspnea as the First Presentation of Mantle Cell Lymphoma:
           A Case Report and Review of the Literature

    • Abstract: Introduction. Acute laryngeal dyspnea is a life-threatening emergency, and the causes in adults are most often laryngeal tumors or inflammatory edema. Lymphoma of the larynx and especially the mantle cell type is extremely rare. Case Presentation. We report a case of a 43-year-old woman with no particular pathological history. She presented with progressive dyspnea which has evolved towards an inspiratory bradypnea that worsened until she ultimately required an emergency tracheotomy. Biopsies revealed mantle cell lymphoma. The patient has been staged IVB MIPI 6, and she was treated by immunochemotherapy followed by ASCT. The therapeutic evaluation shows a complete remission, 18 months after, and the patient was always disease free. Conclusion. The laryngeal localization of the mantle cell lymphoma is extremely rare; it may present catastrophically with acute airway obstruction. The diagnosis is mostly histological, hence the interest of deep biopsy. Given its rarity, the therapeutic strategy must be discussed case by case in a multidisciplinary consultation meeting.

  • Burkitt-Like Lymphoma with 11q Aberration: A Case Report and Review of a
           Rare Entity

    • Abstract: Burkitt-like lymphoma with 11q aberration is a rare diagnostic entity commonly occurring in children and young adults with a nodal presentation. This entity shares many similar morphologic and immunophenotypic features with conventional Burkitt lymphoma and other aggressive B-cell lymphomas, making its recognition challenging. However, the presence of its characteristic 11q gain/loss pattern is helpful in the diagnosis. We report a case of Burkitt-like lymphoma presenting as a right neck mass in a 17-year-old female patient that demonstrated no improvement with antibiotic therapy. The neoplasm displayed a diffuse proliferation of intermediate-sized atypical lymphoid cells with prominent nucleoli in a background of apoptotic debris, morphologically raising concern for conventional Burkitt lymphoma. Subsequent immunohistochemical and cytogenetic studies established the most likely diagnosis of Burkitt-like lymphoma with 11q aberration. Though rare, Burkitt-like lymphoma exhibits significant morphologic overlap with other high-grade B-cell lymphomas, making it an important entity to consider on the differential diagnosis of these lesions.

  • Rivaroxaban Treatment for Heparin-Induced Thrombocytopenia: A Case Report
           and a Review of the Current Experience

    • Abstract: Heparin-induced thrombocytopenia is a life-threatening complication of exposure to heparin. Heparin-induced thrombocytopenia results from an autoantibody directed against platelet factor 4 in complex with heparin. Heparin-induced thrombocytopenia is traditionally treated with bivalirudin, argatroban, danaparoid, or fondaparinux. Recently, direct oral anticoagulants administration to treat heparin-induced thrombocytopenia has been reported. Direct oral anticoagulants do not cause platelet activation in the presence of heparin-platelet factor 4 antibodies, nor do they provoke autoantibody production. Direct oral anticoagulants offer advantages such as consistent and predictable anticoagulation, oral administration with good patient compliance, and a good safety profile. We report a case of heparin-induced thrombocytopenia with deep venous thrombosis successfully treated with rivaroxaban and review the current experience with rivaroxaban for the treatment of heparin-induced thrombocytopenia.

  • PML-RARA Fusion Transcripts Detectable 8 Months prior to Promyelocytic
           Blast Crisis in Chronic Myeloid Leukemia

    • Abstract: Promyelocytic blast crisis arising from chronic myeloid leukemia (CML) is rare. We present a 40-year-old male who developed promyelocytic blast crisis 17 months after CML diagnosis, confirmed by the presence of the t(15;17) and t(9;22) translocations in the leukemic cells. Preserved nucleic acids from routine BCR-ABL1 testing provided a unique opportunity to evaluate clonal progression over time. Retrospective analysis demonstrated PML-RARA fusion transcripts were first detectable 8 months prior to blast crisis presentation. A review of 21 cases of promyelocytic blasts crisis published in the literature reveals a male predominance with earlier age at onset as compared to females. Interestingly, TKI therapy during chronic phase did not impact the time interval between diagnosis and promyelocytic blast crisis. Treatment with standard acute promyelocytic leukemia regimens provides more favorable outcomes with complete molecular remission. Although rare, it is important to consider a promyelocytic blast crisis when evaluating for transformation of CML due to its effective treatment with specific therapies.

           Methyltransferase Inhibitor Achieves Radiological Response in Refractory
           Double-Expressor Diffuse Large B-cell Lymphoma with 17p Deletion

    • Abstract: Double-expressor diffuse large B-cell lymphoma (DLBCL) with 17p deletion is an aggressive and refractory disease. Immune checkpoint blockade and epigenetic drugs have been widely used, but the efficacy of different combined applications varied. We report a case with “double-expressor” DLBCL treated with a combined regimen which consisted of programmed cell death protein 1 (PD-1) inhibitor, DNA methyltransferase inhibitor (DNMTi), and histone deacetylase inhibitor (HDACi). A 50-year-old man presented with a 6-month history of hoarseness, and 10 days of progressive shortness of breath was diagnosed of DLBCL, stage IV. The patient failed to respond to the 1st line (R-EPOCH: rituximab, etoposide, vincristine, cyclophosphamide, doxorubicin, and dexamethasone), 2nd line (R-EPOCH + lenalidomide + ibrutinib), and a 3rd line chemotherapy combined with PD-1 inhibitor (sintilimab), decitabine, and GDP (gemcitabine, DDP, and dexamethasone). Surprisingly, patient’s condition was improved after treatment with PD-1 inhibitor in combination with DNMTi/HDACi. Restaging PET revealed dramatically radiological response.

  • Extensive Bone Marrow Necrosis: A Rare Presentation of Acute Lymphoblastic
           Leukaemia

    • Abstract: Background. Bone marrow necrosis (BMN) is a rare entity which presents with bone pain, fever, and peripheral cytopenia. Acute lymphoblastic leukaemia (ALL) is characterized by malignant proliferation of immature lymphocytes, and patients usually present with fatigue and bleeding manifestations. Presentation with BMN is an extremely rare finding and only few cases had been reported in the literature. Case Presentation. A 22-year-old male presented with nocturnal lower back ache, pleuritic central chest pain, and fever for two weeks. He was extensively investigated for a cause. His investigations revealed pancytopenia with severe neutropenia. Initial bone marrow aspiration and biopsy did not provide a positive result due to extensive necrosis. However, immunohistochemical analysis of few immature lymphoid cells on repeated BM biopsy showed evidence of acute lymphoblastic leukaemia. Conclusions. ALL usually presents with fatigue and bleeding manifestations. Presentation with BMN is extremely rare. The diagnosis was extremely challenging as this patient had only occasional atypical cells in the peripheral blood film and the repeat bone marrow (BM) biopsy showed extensive necrosis.

  • A Case of Parathyroid Adenocarcinoma and Hyperparathyroidism, When
           “CRAB” Symptoms Are Not due to a Plasma Cell Myeloma

    • Abstract: A previously well 49-year-old patient presented to our hospital with symptomatic hypercalcaemia complaining of polyuria and polydipsia, as well as abdominal and lower back pain (serum/ionized calcium at 3.66 milli mole/l and 1.90 milli moles/l). At admission, he had a normocytic anemia (Hb, 99 g/L) and acute kidney injury (creatinine at 161 μM). His parathyroid hormone (PTH) levels were at 67.6 pico moles/l. A plain X-ray of the lumbar spine showed the presence of a lytic lesion in the L4 vertebrae. CT and MRI confirmed this to be a destructive lesion. A subsequent pan CT scan showed a 2.8 cm complex nodule in the left lobe of the thyroid posteriorly. Excisional biopsy of the resected mass was associated with an infiltrative cellular parathyroid neoplasm with solid and nested architectural growth pattern admixed with hemorrhage and focal calcifications. The tumor showed lymphovascular and perineural invasion. At the time of workup and despite the absence of a positive SPEP/UPEP, a bone marrow biopsy was requested to rule out multiple myeloma. His normocellular bone marrow biopsy showed marked paratrabecular fibrosis and extensive bony remodelling but no metastatic invasion. The diagnosis of a metastatic parathyroid carcinoma was made. He is subsequently considered for palliative radiotherapy to the primary tumor bed and the lumbar spine. In addition, a role for immunotherapy with ipilimumab and nivolumab in context of clinical trials is envisioned and he is being considered for enrollment.

  • A Rare Case of Coexisting Breast Cancer and Refractory Acute Myeloid
           Leukemia

    • Abstract: The occurrence of acute myeloid leukemia (AML) within six months from a diagnosis of breast cancer (BC) is rarely reported in the literature, and it is associated with a poor prognosis. We report herein the case of a 40-year-old woman referred to our centre affected by BC and simultaneous AML. The patient proved refractory to first line therapy and achieved complete remission (CR) with a clofarabine-based regimen followed by allogeneic stem cell transplantation (ASCT). Both during salvage chemotherapy and after ASCT, the patient presented severe infectious complications ( acute cholecistytis and Nocardia pneumonia, respectively) treated with surgery, and currently she is alive in CR for both diseases after 29 months of follow-up. The case highlights the importance of a diagnostic assessment of any unexplained cytopenia in association with solid neoplasia under treatment, underlining the feasibility and priority of a timely treatment of the haematological neoplasm in order to achieve long-term survival.

  • T-Cell Large Granular Lymphocytic Leukemia with Extremely Rare
           Immunophenotype (CD4/CD8 Double-Positive) Followed by Multiple Myeloma
           Diagnosis

    • Abstract: T-cell large granular lymphocytic leukemia is characterized by clonal expansion of a CD3+/CD57+ subpopulation, which are typically CD8+ positive cytotoxic T- cells, and can only be diagnosed if there is a persistent, greater than 6 months, elevation of LGL in the blood (usually 2–20 × 109/L), in the absence of an identifiable cause. T-LGLL has been associated with reactive conditions such as autoimmune diseases and viral infections and has also been reported in association with hematologic and non-hematologic malignancies. We report a case of asymptomatic CD4/CD8 double-positive T-LGLL. Flow cytometry on peripheral blood revealed a subpopulation of CD4/CD8 double-positive T cells expressing CD57 and cTIA. Clonality was established by flow cytometric analysis of T-cell receptor V(â) region repertoire which showed that >70% of the cells failed to express any of the tested V(â) regions. Clonality was further confirmed by PCR with the detection of clonal TCR beta and TCR gamma gene rearrangements. Six months later, she presented with persistent lower back pain and diagnosed with IgG kappa multiple myeloma. CD4/CD8 double-positive T-large granular leukemia is the first case reported in the literature. This rare phenotype is either underreported or a truly rare clinical entity. More studies are warranted to characterize the pathogenesis and clinical characteristics of this group of patients and to further assess the relationship between multiple myeloma and T-LGLL as a cause-and-effect relationship or simply related to the time at which diagnosis has been made.

  • Treatment of T-Cell Prolymphocytic Leukemia with Central Nervous System
           Involvement Using Intrathecal Alemtuzumab Administration

    • Abstract: T-cell prolymphocytic leukemia (T-PLL) is a rare hematologic cancer with a dismal prognosis. Although a small number of patients have central nervous system (CNS) involvement, a standard treatment approach for these patients has not been established. Herein, we present a case of T-PLL with CNS involvement that was treated with a higher dose of intrathecal alemtuzumab than that previously reported. A 66-year-old man who had T-PLL with CNS involvement was admitted to our hospital. Intravenously administered alemtuzumab, a monoclonal antibody against the CD52 antigen, successfully reduced leukemia cells in peripheral blood; however, intrathecal treatment with methotrexate, cytarabine, and prednisone had a limited effect on the CNS involvement. Therefore, we intrathecally injected alemtuzumab as an experimental treatment. Although we escalated the dose of intrathecal alemtuzumab up to 5 mg, no adverse reaction was noted; however, this treatment did not completely clear the leukemia cells from the patient’s cerebrospinal fluid (CSF). We performed whole brain and whole spinal irradiation therapies and subsequently performed allogeneic transplantation from a human leukocyte antigen-matched sibling donor with a conditioning regimen containing total body irradiation. At 21 days after transplantation, leukemia cells remained in his CSF. Although intrathecal alemtuzumab did not eliminate the CNS-invading leukemia cells, it was well-tolerated in our case. Further accumulation of similar cases is needed to determine the benefits and safety of intrathecal alemtuzumab administration.

  • Extramedullary Solitary Plasmacytoma with Anaplastic Features of the
           Nasopharynx

    • Abstract: Extramedullary plasmacytomas (ESPs) are rare forms of plasma cell dyscrasias and usually are seen in the upper aerodigestive tract. ESPs with anaplastic features are extremely rare, and no treatment guidelines exist. We present a 75-year-old gentleman presented with left nasal blockage, and on examination, a polypoid left nasal mass was seen. He was, then, referred to ENT after a CT scan revealed a mass in the left nasopharynx for a biopsy. The preliminary reports suggested a high-grade lymphoma; however, after further testing, it was revealed to be an anaplastic plasma cell neoplasm. PET scan, bone marrow biopsy, serum and urine protein electropheresis, serum immunofixation and light chains were all unremarkable for systemic disease. Differential diagnosis included plasmablastic lymphoma, NK/T cell lymphoma-nasal type, and squamous cell cancers of the head and neck. He was treated with radiation alone given his comorbidities. Given there are no treatment guidelines, we would like to highlight this rare case and discuss different potential management options such as radiation, chemotherapy, surgery, or a combination of different modalities.

  • Hemophagocytic Lymphohistiocytosis (HLH) in a Patient with Disseminated
           Histoplasmosis

    • Abstract: Hemophagocytic lymphohistiocytosis (HLH) is a rare condition characterized by an overwhelming inflammatory cascade activation which is often associated with rapid progression and high mortality. It may be familial with an underlying genetic mutation or triggered by infection, malignancy, and autoimmune disease. Disseminated histoplasmosis caused by histoplasma capsulatum is a granulomatous fungal disease seen typically in immunocompromised patients with varied clinical manifestations and requires long-term antifungal therapy. We present the case of a 61-year-old immunocompromised female with significant travel history who came with fever, pancytopenia, and liver failure raising suspicion for HLH that prompted a bone marrow biopsy procedure. Hemophagocytic figures consistent with HLH and numerous encapsulated fungi resembling histoplasma were visualized. She was treated with intravenous (IV) liposomal amphotericin B. Etoposide chemotherapy and interleukin-1 (IL-1) antagonist anakinra were deferred in order to limit her immunosuppression, and treatment was focused on antifungal therapy.

  • A Case with Hepatic Involvement Mimicking Metastatic Disease in Multiple
           Myeloma

    • Abstract: Multiple myeloma is a type of plasma cell disorder and can be seen in different forms. According to current knowledge, it is not a curable disease. Smoldering multiple myeloma (SMM) is an asymptomatic clonal plasma cell disorder and distinguished from monoclonal gammopathy of undetermined significance by a much higher risk of progression to multiple myeloma. We present a 53-year-old female patient who started with SMM which turned into multiple myeloma after four years. Despite 26 cycles of lenalidomide treatment, we performed the second autologous stem transplantation. After 12 years from the diagnosis of the disease, it was transformed into plasma cell leukemia and widespread nodular lesions were seen in the liver. Different presentations could be seen due to malignant plasma cell infiltrations or primary amyloidosis. Liver involvement is one of them and is less common than other organ involvement. We report a case of myeloma presenting with extensive nodular involvement in the liver and misdiagnosed as metastatic disease. It is important because of its rarity and change of the treatment approach.

  • Prefibrotic Myelofibrosis Presenting with Multiple Cerebral Embolic
           Infarcts and the Rare MPL W515S Mutation

    • Abstract: Acquired, activating mutations of MPL W515 are recognised driver mutations of the myeloproliferative neoplasms (MPN), namely, essential thrombocythemia and primary myelofibrosis. The most common mutation at this codon is W515L with several other mutations also described at a lower frequency. Of these less common mutations, MPL W515S has only been reported sporadically with limited information on clinicopathological associations. We describe the case of an elderly man with persistent thrombocytosis presenting with an ischemic cerebral event. Bone marrow biopsy showed evidence of prefibrotic myelofibrosis with targeted sequencing demonstrating the presence of the rare MPL W515S mutation. Thrombolytic and cytoreductive therapies resulted in a favorable outcome and follow-up. This case provides additional, necessary, and phenotypic data for the rare MPN-associated MPL W515S mutation.

    • Abstract: Venous thromboembolism occurs when a deep vein thrombosis travels to the lungs and forms a pulmonary embolism. Low-molecular-weight heparins are a mainstay in the treatment and prevention of venous thromboembolism and should be initiated promptly due to substantial morbidity and mortality. A rare side effect of low-molecular-weight heparins is major bleeding, which also carries a significant morbidity and mortality rate. Here, we present a case of a fatal retroperitoneal hematoma in a patient being treated with enoxaparin for bilateral pulmonary emboli.

  • Hereditary Hyperferritinemia-Cataract Syndrome in 3 Generations of a
           Family in East Tennessee

    • Abstract: Hereditary hyperferritinemia and cataracts syndrome (HHCS) without iron overload is a syndrome first identified less than 3 decades ago. While investigators have dissected the gene where several responsible mutations reside, it remains a relatively unknown genetic disorder to clinicians. The result is often an expensive, invasive evaluation for iron overload, followed by a well-intended prescription for a series of phlebotomies that delivers morbidity instead of benefit. We present a father with an elevated ferritin and heterozygosity for H63D HFE mutation whose clinical course followed this path. His treatment rendered him symptomatic from iron deficiency with no reduction in his ferritin. On re-evaluation, a review of his past medical history clarified the cataract surgery noted in his record had occurred at a young age. Furthermore, one of his daughters required cataract surgery as a teenager. With this information, we strongly suspected HHCS. His phlebotomies were discontinued, and within weeks, his iatrogenic iron deficiency resolved and his health returned to normal.

  • Chronic Atrophic Gastritis with Negative Intrinsic Factor and Parietal
           Cell Antibody Presenting as a Severe Hemolytic Anemia

    • Abstract: A 28-year-old Caucasian male with Hashimoto’s disease and vitiligo presented with two weeks of dizziness on exertion following pharyngitis which was treated with prednisone 40 mg by mouth once a day for five days. Initial workup revealed anemia, elevated lactate dehydrogenase (LDH), and low haptoglobin. He underwent workup for causes of hemolytic anemia which was remarkable for a peripheral blood smear with hypersegmented neutrophils and low vitamin B12 levels concerning for pernicious anemia. Parietal cell and intrinsic factor antibodies were negative, and he then underwent an esophagogastroduodenoscopy with biopsy. The biopsy was negative for Helicobacter pylori, and the immunohistochemical stains were suggestive of chronic atrophic gastritis. He was started on vitamin B12 1,000 mcg intramuscular injections daily. His hemoglobin, LDH, and haptoglobin normalized. Given the absence of the parietal cell antibody and intrinsic factor antibody, this is a rare case of seronegative pernicious anemia.

  • Two Consecutive Episodes of Severe Delayed Hemolytic Transfusion Reaction
           in a Sickle Cell Disease Patient

    • Abstract: Patients with sickle cell disease (SCD) suffer from anemia and painful vaso-occlusive crisis (VOC) and sometimes need blood transfusions. Delayed hemolytic transfusion reaction (DHTR) is a rare life-threatening complication observed in SCD and mimics VOC. We describe a female SCD patient undergoing three surgical procedures during which DHTR developed following the first two. Prior to a planned tonsillectomy, she received transfusion and three days after surgery developed severe hemolysis as well as pain and respiratory symptoms. On suspicion of VOC, she received additional transfusions and became hemodynamically unstable, and her hemolytic anemia worsened. Gradually, she recovered and could be discharged after two weeks; DHTR was not suspected. Sixteen months later, an arthroplasty was performed due to avascular necrosis, and again she was transfused preoperatively. Similar to the initial surgery, she developed symptoms and signs of VOC after three days, but this time, DHTR was suspected and further transfusions were withheld. Although immunosuppressive medication did not alleviate the condition, she improved on combined treatment with darbepoietin, rituximab, and eculizumab. Six months later, a second arthroplasty was performed uneventfully after prophylaxis with rituximab and without transfusion. DHTR should be considered in the presence of severe, unexplained hemolysis following a recent transfusion, and additional transfusions in this setting should be given only on vital indication.

  • Spontaneous Spinal Epidural Hematoma in a Patient on Apixaban for
           Nonvalvular Atrial Fibrillation

    • Abstract: Background. With the rise in the use of direct oral anticoagulants (DOACs), more hemorrhagic complications are being encountered. Since the first description of a case of spontaneous spinal epidural hematoma (SSEH) related to the utilization of DOACs in 2012, there have been few reports describing a similar association. However, no cases so far have reported an association between SSEHs and apixaban. Case Description: A 76-year-old lady, with a history of nonvalvular atrial fibrillation, presented with a new onset of progressive left lower and upper extremity weakness. She reported back pain and numbness in the left leg up to the knee along with numbness in the left arm up to the shoulder. A CT scan of the neck was suggestive of an epidural hematoma extending from C2-C3 level to C6-C7. As the patient was on apixaban at the time, surgical treatment was delayed for two days to decrease the risk of intraoperative bleeding. Nine days later, she was discharged. Her physical exam was almost unchanged from that on presentation, except for resolution of pain and minimal improvement in motor power in her left lower extremity from 1/5 to 2/5 distally. Conclusions. Spinal hematomas represent surgical emergencies with earlier intervention portending better outcome. Based on the few case reports that point to DOACs as a potential culprit, it appears that a high suspicion index resulting in earlier SSEH diagnosis and intervention is crucial for improved neurological outcome and recovery. Prompt diagnosis remains a challenge, especially that SSEH can mimic cerebrovascular accidents.

  • CD7-Positive Diffuse Large B-Cell Lymphoma Presenting as an Intranasal
           Tumor

    • Abstract: We report a case of a 74-year-old man with a cluster of differentiation (CD) 7-positive diffuse large B-cell lymphoma (DLBCL) in the right nasal cavity. Flow cytometry analyses showed CD7 and CD20 positivity in tumor cells. The patient received 6 cycles of R-CHOP plus local radiation therapy because positron emission tomography-computed tomography after R-CHOP revealed an intranasal lesion. The patient achieved complete remission (CR) after radiation therapy. The frequency of CD7-positive DLBCL is rare, and only 11 cases with follow-up of clinical course have been reported thus far. CR or partial response was noted in 8 of 11 cases after receiving rituximab combined with chemotherapy. In total, 9 of 12 cases involved the development of extranodal lesions, which occurred as an intranasal tumor in 3 cases. It is important to examine the clinical features by accumulation of further cases.

  • Reactivation of Epstein–Barr Virus Presenting as Massive Splenomegaly
           after Initiation of Golimumab Treatment

    • Abstract: Epstein–Barr virus infection is most commonly asymptomatic in the acute setting, where the end result of infection is the adoption of a viral latency phenotype. The virus can reactivate later in life leading to the abnormal proliferation of the infected B, T, or NK cells. Hereby, we report a 71-year-old female with seronegative rheumatoid arthritis who presented with massive splenomegaly, pancytopenia, and positivization of antibodies against double-stranded deoxyribonucleic acid (dsDNA) after initiation of the anti-tumor necrosis factor (TNF) golimumab. The diagnosis of EBV-associated lymphoproliferative disorder (LPD) was demonstrated by elevation of the plasmatic EBV viral load. Withdrawal of the anti-TNF and treatment with the anti-CD20 antibody rituximab were able to revert the clinical abnormalities. EBV-associated LPDs are described after initiation of other anti-TNF agents, such as infliximab, but no reports of golimumab-associated EBV LPD are found in the literature. The mechanisms for this occurrence are not clear, but these are known to involve expression of a panel of viral proteins specific to the viral latency phenotypes.
