  • Toxoplasmosis Presenting as Nonhealing Cutaneous Ulcer

    • Abstract: Introduction. Systemic manifestation of toxoplasmosis is commonly seen in immune-compromised individuals. Skin manifestations are seen commonly in conjunction with systemic features. Isolated cutaneous toxoplasmosis is extraordinarily rare in immunocompetent patients. Case Description. A 64-year-old female presented to the Dermatology Outpatient Department (OPD), with a nonhealing ulcer over dorsum of the left hand for one year. The patient did not have any systemic diseases. Serology tests were negative. An incisional biopsy of the lesion revealed dense inflammatory cell infiltrates comprising predominantly of plasma cells and lymphocytes, multinucleated giant cells, and focal abscess formation in the dermis. Periodic Acid Schiff (PAS) stain showed organisms in the dermis with morphological resemblance to tachyzoites of Toxoplasma gondii. Conclusion. Though rare, a possibility of primary cutaneous toxoplasmosis should always be considered and looked for, even in immunocompetent patients presenting with chronic nonhealing ulcers.

  • Colonic Adenocarcinoma at Advanced Stage in Adolescence: Report of 2 Cases

    • Abstract: Background. Carcinoma of colon is rare in children and adolescents. The staging criteria of the carcinoma is the same as those for adults. However, the pathogenetic background in pediatric cases is different from adults and usually involves mismatch repair gene mutations or familial polyposis syndromes. Case report. We describe two adolescents diagnosed with advanced stage colon carcinoma and discuss the histological appearance, testing for mismatch repair genes and contrast- it with carcinoma occurring in the setting of familial polyposis syndrome. Conclusion. Colonic carcinoma occurring in pediatric patients should prompt a work-up for mismatch repair gene mutation status. Despite higher stage of presentation, some of the pediatric patients may respond favorably to chemotherapy and surgical resection.

  • Unusual Case of Anaplastic Large Cell Lymphoma Presenting as a Breast Mass
           in a Patient with no History of Breast Implants

    • Abstract: Adenocarcinoma is the most common malignant neoplasm involving breast tissue. In contrast to carcinomas, the other types of malignant neoplasms involving the breast are relatively uncommon. One of the examples of this rare entity is lymphoma. Traditionally, non-Hodgkin lymphomas (NHL) involving the breast are divided into primary lymphoma of the breast and systemic lymphoma, although the distinction could be challenging. Most of NHL involving breast tissue have B cell origin; T cell NHL represents less than 20% of all lymphoma cases. Anaplastic large cell lymphomas (ALCL) involving the breast accounts for even lower percentage of cases. Similar to ALCL involving other sites, there are several main types of ALCL identified: primary cutaneous ALCL and systemic ALCL, which is subdivided into ALK positive and ALK negative subtypes. Relatively recently, an additional distinct subtype of ALK-negative ALCL was described, which is associated with textured breast implants and needs to be considered as a differential diagnosis if patient has a history of breast implants. Here, we report a case of ALCL presented as a breast mass without history of breast implant and discuss similar cases published in the literature.

  • Along for the Ride: Intrahepatic Cholangiocarcinoma with Concomitant LECT2
           Amyloidosis

    • Abstract: We present a case of a 69-year-old Hispanic male with a past medical history of type II diabetes mellitus who presented with a two-month history of abdominal pain. A CT scan was performed which identified a liver mass. Biopsy of the liver mass revealed infiltration of normal liver parenchyma by atypical glands surrounded by pale eosinophilic material. The atypical glands were positive for CK7, while negative for CK20, CDX-2, and TTF-1, consistent with intrahepatic cholangiocarcinoma. A Congo red stain was performed, which highlighted salmon-orange areas, some with a globular appearance, around the glands and within the sinusoids and vasculature. Under polarized light, these areas displayed apple-green birefringence. These findings were consistent with amyloidosis, which was further supported by identification of ALECT2- (leukocyte chemotactic factor-2-) type amyloid on mass spectrometry. To our knowledge, this is the first documented case of intrahepatic cholangiocarcinoma arising in association with LECT2 amyloidosis.

  • Involvement of Annexin A2 Expression and Apoptosis in Reverse Polarization
           of Invasive Micropapillary Carcinoma of the Breast

    • Abstract: Invasive micropapillary carcinoma (IMPC) is characterized by pseudopapillary tumor-cell clusters with a reverse polarity (RP) floating in lacunar spaces, with aggressive biological characteristics. The RP prevention is considered to inhibit IMPC, but its pathogenic mechanisms remain unclear. Annexin A2 (ANX A2), a cell-polarity protein, is known to be involved in lumenogenesis. ANX A2 expression is immunohistochemically examined, as well as both epithelial membrane antigen (EMA) and mucin-1 glycoprotein (MUC-1), the gold-standard markers for luminal differentiation, in the background tumor components of a case of IMPC. The following findings were noticed: (1) Apoptosis was scattered with peripheral apoptotic vacuolar change; (2) EMA and MUC-1 expressions were found, rimming the peripheral apoptotic vacuoles (including the contact surface with neighboring tumor cells), and these positions corresponded to the ones with a distinct ANX A2 positivity; and (3) partially detached tumor cells showed distinct positivity of three proteins at the stroma-facing surface, which is consistent with a RP. Taken together, frequent apoptosis in tumor cells with membranous accumulation of ANX A2 is considered to be indispensable for the reverse polarization of IMPC, and that secondary necrosis following apoptosis induces the cell-polarity disorder and creates detached tumor cells with a RP.

  • Benign Histiocyte-Rich Pseudotumor Developing Postchemotherapy and
           Mimicking Residual Disease

    • Abstract: Histiocyte-rich pseudotumors (HRPT) developing postchemoradiation therapy are a florid response to treatment and reparative change. Although these are benign processes, clinically and radiologically, these may mimic recurrent/relapsed disease. We describe a case of an adult male with history of diffuse large B-cell lymphoma (DLBCL), status postchemoradiation therapy, who developed HRPT at the site of original involvement, mimicking relapse of disease on positron emission tomography/computed tomography (PET/CT) imaging. This is one of the few reported cases of posttreatment HRPT. This entity is important to point out the limitations of PET/CT imaging in patients with lymphomas and metastatic disease and stresses the importance of an excisional biopsy for determining relapse and the need for further treatment.

  • Rare Development of Primary Parotid Gland Epithelial-Myoepithelial
           Carcinoma in a Child

    • Abstract: Salivary gland tumors are uncommon in children. They consist of variable histopathological subtypes of benign and malignant tumors. EMC is a discrete entity among the WHO classification of salivary gland tumors since 1991. EMC is considered a low-grade malignant salivary gland tumor arising from intercalated ducts. Typically, it affects an adult female individual. Surgical resection with a negative margin is the mainstay treatment option. EMC has a potential for metastasis with a high rate of recurrence. Based on the available English literature, two cases of EMC diagnosed in a pediatric age group have been reported. Therefore, we describe the third EMC that developed in the left parotid gland of a young child. The diagnosis of EMC was established through histopathological examination of the total parotidectomy specimen and neck lymph node dissection, together with ancillary studies. Later, the patient suffered from cervical lymph node enlargement due to metastasis in which FNAB was taken. Metastasis from the known EMC was suspected with cytomorphological features in smears and cell block. Immunohistochemistry markers for the biphasic components were supportive of EMC. Due to advanced disease, the patient necessitated a concomitant treatment of radiochemotherapy. Besides, there was radiological evidence of bilateral multiple lung metastatic nodules. However, a biopsy was not sent for pathological confirmation.

  • Paraneoplastic Pemphigus Involving the Respiratory and Gastrointestinal
           Mucosae

    • Abstract: Paraneoplastic pemphigus (PNP), an autoimmune mucocutaneous disorder involving the oral and bronchial mucosae, is a rare complication of hematologic malignancy. Serologically, serum autoantibodies against varied desmosome-related proteins are of notice. PNP is often lethal due to bronchiolitis obliterans and opportunistic infection. A 70-year-old Japanese male complained of dry cough, stomatitis, and sore throat. The lips and oral mucosa were severely eroded, and skin eruptions were seen on the chest and abdomen. The biopsy features were consistent with PNP, and the deposition of IgG and IgM was shown on the plasma membrane of the involved keratinocytes. Serological studies demonstrated autoantibodies to desmoglein-3, desmocollins-2 and -3, bullous pemphigoid antigen-1, envoplakin and periplakin. Systemic evaluation disclosed mantle cell lymphoma, stage 4B. After chemotherapy, partial remission was reached. PNP was treated with methylprednisolone and intravenous immunoglobulins, and the oral lesion only temporarily responded. He died of respiratory failure two months after onset. Autopsy revealed residual indolent lymphoma and systemic opportunistic infections. Aspergillus colonized the eroded bronchial/bronchiolar mucosa, associated with extensive vascular invasion. Coinfection of cytomegalovirus (CMV) and Pneumocystis jirovecii caused interstitial pneumonia. The oropharyngeal, respiratory, esophageal, and gastrointestinal mucosae were diffusely infected by CMV. Bronchiolitis obliterans was observed in the peripheral lung. PNP-related acantholysis-like lesions were microscopically identified in the bronchial and gastrointestinal mucosa. IgG deposition and cleaved caspase-3-immunoreactive apoptotic cell death were proven in the involved mucosal columnar cells. Pathogenesis of the mucosal involvement is discussed.

  • Localized Breast Amyloidosis Associated with Sjörgren Syndrome

    • Abstract: Sjörgren syndrome is a systemic autoimmune disease that is rarely associated with amyloid deposits, and in most reported cases, these deposits are localized to a single organ. Amyloidosis of the breast is a rare and unexpected finding, and only 5 case series with 63 patients have been published in the past 40 years. To date, only 6 cases have been reported in which Sjörgren syndrome is associated with amyloid deposits in the breast. A 61-year-old female diagnosed with Sjörgren syndrome underwent a breast needle core biopsy for calcifications. Microscopic examination revealed amyloid deposits in the periductular basement membranes, in the walls of arteries and veins, and in the surrounding connective tissue. No malignancy was found. Clinical workup revealed the amyloid deposits to be localized to the breast and did not reveal an underlying hematolymphoid neoplasm. The association between Sjörgren syndrome and breast amyloidosis is rare, but few reports have appeared in recent years, and it may be an emerging disease association. The finding of localized amyloid in the breast and other organs should lead to a clinical workup not only for hematopoietic neoplasms but also for autoimmune diseases such as Sjörgren syndrome.

  • The Rare Case of an Adult-Onset Xanthogranuloma of the Paranasal Sinuses:
           A Histological Dilemma

    • Abstract: Xanthogranuloma is a rare benign tumour, part of the non-Langerhans cell histiocytosis group, uncommon in adults and even less common in the paranasal sinuses. Despite its benign nature, it mimics neoplasm due to its local effects which can have serious functional consequences depending on the anatomical location. We present the rare case of a young lady who presented insidiously with a maxillary sinus xanthogranuloma and was treated with endoscopic resection. Tissue diagnosis is of paramount importance to guide correct further investigations and management, and we discuss the potential challenge in identifying such a rarely seen pathology.

  • Synovial Sarcoma of the Hand

    • Abstract: The incidence of synovial sarcoma is 1.548 per 1,000,000. Synovial sarcoma localized to the palmar surface should, therefore, be considered extremely rare. This report documents a 34-year-old male with a right hand mass that had been present for a few years, continuing to grow in size. The mass was located at the palm and extended from the mid-third metacarpal to involve all digits except the thumb. The mass was determined to be monophasic synovial sarcoma on histopathologic exam. Fluorescence in situ hybridization for SYT gene rearrangement was positive in 72% of cells. Resection of the mass was followed by radiation and chemotherapy. The patient had a long-term follow-up of 3.5 years with no evidence of any local recurrence of the tumor. This report increases awareness of this extremely rare malignancy—an awareness that is crucial for early diagnosis and improved survival rates. It is more common at younger ages but it can occur at any age, so it should be suspected and included in the differential diagnosis, especially when evaluating slow growing, nonresolving hand lesions.

  • Placental Findings in Lysosomal Storage Disease Diagnosis: A Case Report
           of Galactosialidosis

    • Abstract: Introduction. Lysosomal storage disorders (LSDs) are rare diseases with more than 50 different entities described today. The spectrum of phenotypes varies from severe to lethal and early-onset disease to mild and late onset. Recognition of the clinical signs and diagnostic workup is challenging and requires expertise. Diagnosis relies on finding abnormal metabolites in urine and serum followed by further enzymatic or molecular analysis. Routine histological examination of the foetal and placental tissues frequently shows vacuolisation, providing a readily available important clue to the diagnosis. Case Report. A third child of consanguineal parents showed several dysmorphic features and a complicated neonatal period with eventual demise in the early postneonatal period due to respiratory failure. An LSD was suspected based on clinical presentation, urine metabolite excretion, skeletal radiograph, and vacuolisation in lymphocytes and placental tissues on, respectively, blood smear and routine histological examination. Homozygosity mapping favoured galactosialidosis. The diagnosis was confirmed by massive parallel sequencing, revealing a single nucleotide variation in the CTSA gene (c.265A>C, p.Ser89Arg). Discussion. Histological placental examination may be either the first clue or complimentary evidence in recognizing LSDs. It is important to recognize these clues as it may prompt further investigation and facilitate earlier recognition of the disease.

  • Breast Implant-Associated Anaplastic Large Cell Lymphoma

    • Abstract: Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a rare, non-Hodgkin lymphoma which arises within the capsules of breast implants. These particular tumours have expression of CD30 and are negative for Anaplastic Lymphoma Kinase (ALK). Here, we report a case of BIA-ALCL in a 48-year-old woman post breast reconstruction. This case report is aimed at raising awareness and education on the significance of considering the development of BIA-ALCL in cases where cytology is negative and helping better understand this disease process.

  • Medullary Thyroid Carcinoma Presenting as Metastatic Disease to the Breast

    • Abstract: Medullary thyroid carcinoma (MTC) is a neuroendocrine tumor that is derived from C cells of the thyroid gland. It is a rare aggressive tumor, known to metastasize to lymph nodes, liver, bones, and lungs. A 41-year-old female, who presented with a breast mass, was initially diagnosed with invasive ductal carcinoma. She was also found to have a thyroid mass which was later diagnosed as MTC. On a rereview of the breast pathology, the morphologic features were strikingly similar to the MTC. Further investigation revealed that this was in fact a very rare case of MTC that had metastasized to the breast. We have identified 20 cases of MTC metastasizing to the breast in the literature that supports its occurrence as a real possibility. Albeit rare, medullary thyroid carcinoma should be considered in the differential diagnosis of a breast mass.

  • Hydrocele of the Canal of Nuck with Endometriosis: Right-Side Dominance
           Confirmed by Literature Review and Statistical Analysis

    • Abstract: Introduction. The canal of Nuck is an embryological remnant of the peritoneal pouch that extends into the labium majus of women. Hydrocele is the most common presentation, but only a small number of cases are reported in association with endometriosis. Case Presentation. The patient is a 45-year-old woman who presented with left inguinal mass with persistent pain. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed a 30 mm cystic mass, and a hydrocele of the canal of Nuck (HCN) was suspected. The excised mass was a cyst containing yellow-tan serous fluid, and the cyst wall was lined by mesothelium. The morphology was consistent with conventional HCN. However, since several foci of endometrial-like epithelium and stroma were identified beneath the mesothelium, the mass was diagnosed with HCN with endometriosis (EM-HCN). Discussion. Right-side dominance of EM-HCN is suggested by several authors, but a thorough review has never been performed. For the first time, we reviewed the literature and statistically confirmed that EM-HCNs dominantly occur on the right side compared to those without endometriosis. We consider that this supports the theory that endometriosis derives from retrograde menstruation of endometrial tissue through fallopian tubes. When endometriosis is discovered in HCN, the clinician should be aware of the possibility of pelvic endometriosis.

  • Chondro-Osseous Metaplasia in Ependymoma: A Rare Histopathological Finding

    • Abstract: Ependymoma is a circumscribed glioma composed of uniform glial cells with bland nuclei in a fibrillary matrix. It is characterized by the presence of perivascular pseudorosettes. Unusual histopathological findings have rarely been reported in ependymomas, 0.5% of all diagnosed cases. Such unusual and exceedingly rare histological findings include osseous or chondroid metaplasia. To the best of our knowledge, only 15 cases of osseocartilaginous ependymomas have been reported in English literature. We report a 3-year-old boy who presented with ataxia, vomiting, and headache for three months. Radiological imaging revealed a posterior fossa lesion. Histopathological examination of the lesion confirmed a posterior fossa ependymoma with chondro-osseous metaplasia. The present case outlines the clinical presentation, histopathological findings, and outcome of chondro-osseous metaplasia in ependymomas. To date, the etiology of chondro-osseous metaplasia in ependymomas remains uncertain. Further research exploring such phenomenon is of paramount importance to explain how these tumors develop.

  • Neuronal Differentiation in a Pituitary Macroadenoma with Focal Small Blue
           Round Cell Morphology: Report of a Rare Pattern

    • Abstract: Ganglion cell-containing pituitary adenomas that are neurofilament protein-positive are the exceedingly rare form of pituitary ganliocytomas. We report a case of a 23-year-old male patient who presented with a clinical picture of acromegaly in addition to raised prolactin level. Histopathology showed areas exhibiting pseudopapillary and solid proliferation of round and monotonous blue cells. The immunohistochemistry showed strong reactivity for synaptophysin and growth hormone and focal reactivity to prolactin. Fibrous bodies are confirmed using cytokeratin immunostain, in keeping with sparsely granulated somatotroph component. The patient remained free of recurrence after one year of radiological follow-up.

  • Pulmonary Alveolar Microlithiasis: An Isolated Case in a Hispanic Male

    • Abstract: Pulmonary alveolar microlithiasis (PAM) is an uncommon hereditary lung disease characterized by widespread deposition of calcium phosphate microliths within the alveolar spaces. It is considered an autosomal recessive disease with a mutation in a gene encoding a sodium phosphate cotransporter. The imaging findings in the early phase of disease can be mistaken for miliary tuberculosis or sarcoidosis. However, the classic radiologic findings in the later phases of disease show numerous opacities causing a “snowstorm” appearance to the lungs that corresponds with widespread deposition of microliths throughout the lung parenchyma. Although the disease often progresses over a slow time course, there are no effective therapies, and bilateral lung transplantation is recommended when there are increasing oxygen requirements or evidence of pulmonary hypertension.

  • Adenocarcinoma with Neuroendocrine Differentiation of the Colon
           Accompanying Osteoclast-Like Giant Cells

    • Abstract: Introduction. Neuroendocrine differentiation in colorectal cancer is reportedly associated with poorer grade of tumor differentiation, nodal and distant metastasis, and other unfavorable features, contributing to a worse clinical outcome. Colorectal cancer with osteoclast-like giant cells (OGCs) is extremely rare. Case Presentation. An 86-year-old woman was diagnosed as double cancer of the transverse and sigmoid colon. Both tumors were simultaneously removed. The transverse colon cancer directly invaded the area of the right gastroepiploic vessels and spread to the nodes and histologically consisted of both the tubuloglandular and solid components. CD8/granzyme B-positive tumor-infiltrating lymphocytes and CD163/CD68-positive macrophages, frequently forming OGCs, were observed particularly at the invasion front. The carcinoma cells were labeled focally for synaptophysin and diffusely for the DR locus of the human leukocyte antigen and programmed death-ligand 1 (PD-L1). Deficient expression of DNA mismatch repair (dMMR) proteins was immunohistochemically confirmed. The patient died 16 months after surgery. Conclusion. This is the first report of colonic adenocarcinoma with neuroendocrine differentiation accompanying OGCs. Histopathologic factors of the poor prognosis in the present case included (a) the presence of more than 2% cells with neuroendocrine differentiation, (b) infiltration of CD163/CD68-positive OGCs at the invasion front, (c) deficiency of dMMR proteins, and (d) PD-L1 expression.

  • Erdheim-Chester Disease and Small Lymphocytic Lymphoma Collision Tumour
           Presenting as a Perirenal Mass

    • Abstract: Background. Erdheim-Chester disease is a rare histiocytic neoplasm associated with MAPK pathway mutations. Disease manifestation is variable often involving many different organs, mainly bone, retroperitoneum, the heart, and the central nervous system. Histological findings include foamy histiocytes in a fibrous stroma with scattered inflammatory infiltrate. Histiocytes are CD68 positive and S100 negative. Case Report. We report a case of Erdheim-Chester disease associated with small lymphocytic lymphoma presenting as a perirenal mass with a review of the recent literature. Conclusions. Erdheim-Chester disease rarely can be associated with other cancers, namely myeloid neoplasms. We report a case of Erdheim-Chester disease presenting with small lymphocytic lymphoma as a perirenal mass. The association of Erdheim-Chester disease with lymphoproliferative disorders needs to be elucidated.

  • Primary Angiosarcoma of the Thyroid in an Asian Woman: A Case Report with
           Review of the Literature

    • Abstract: Primary thyroid angiosarcoma is a rare malignant tumor and characterized by its prevalence in Alpine regions of Central Europe, close relation to longstanding goiter, and aggressive clinical course with dismal prognosis. We describe the case of an 83-year-old Chinese female who lives in the coastal area of Taiwan. She came to our hospital due to a progressively enlarged mass at her anterior neck. The sonography of the thyroid revealed a well-circumscribed mass in the left lobe. She underwent left hemithyroidectomy. The diagnosis of angiosarcoma of the thyroid was made and further confirmed at a different institution. To the best of our knowledge, this is the first case of primary thyroid angiosarcoma reported from Taiwan and the sixth Asian afflicted with primary thyroid angiosarcomas in the English literatures. The literature search in the PubMed database identified 58 cases who had histologically proven primary thyroid angiosarcomas. A preliminary analysis of epidemiological presentation, clinical features, immunohistochemical characters, and prognosis of primary thyroid angiosarcoma was proposed. The prognosis of this rare neoplasm is surprisingly favorable in comparison with that of its morphological similar, the anaplastic thyroid carcinoma. The use of a comprehensive panel of immunohistochemical stains, including at least two endothelial markers (especially CD31 and ERG) and PAX-8, in combination with thorough light microscopic examination may assist in the discrimination between these two tumors.

  • Ovarian Mixed Malignant Brenner-Mucinous Tumor with Signet Ring Cells

    • Abstract: Mucinous carcinomas with signet ring cells in the ovary, particularly those composed predominantly of signet ring cells, are extremely rare, and in vast majority of cases, they represent metastasis from another site such as the stomach, appendix, pancreaticobiliary tract, bladder, and breast (Hristov et al., 2007, Kiyokawa et al., 2006, Vang et al., 2006, Young, 2006). Malignant Brenner tumor is also rare comprising less than 0.5% of ovarian carcinoma. Although mixed Brenner-Mucinous tumors are relatively common, the combination of a primary ovarian signet ring carcinoma with a malignant Brenner tumor is unique and to the best of our knowledge not previously reported in the literature.

  • Masson’s Tumor of the Hand: An Uncommon Histopathological Entity

    • Abstract: Masson’s tumor or Masson’s hemangioma, more precisely termed intravascular papillary endothelial hyperplasia (IPEH), is an uncommon benign vascular lesion of the skin and subcutaneous tissues which can be frequently confused with angiosarcoma. Although relatively rare, its accurate diagnosis is essential since it can clinically be similar to both benign and malignant lesions. We present a 39-year-old man with a round bulging arising from the left palm side of the hand with gradual growth in the last 5 months and on and off tenderness. The microscopic section demonstrated the papillary proliferation of endothelial cells in favor of Masson’s hemangioma, which was sufficiently treated with excision alone.

  • Large Cell Calcifying Sertoli Cell Tumor with Macrocalcification in a
           Partially Resected Testis

    • Abstract: Large cell calcifying Sertoli cell tumors (LCCSCTs) are extremely rare, with less than 100 tumors being described to date. Most of the tumors are benign with a few malignant cases, and aggressive behavior is infrequent. These tumors are a type of Sertoli cell tumor, and these tumors comprise less than 0.3% of all testis tumors in Saudi Arabia. They usually occur in boys and young adults and can affect one or both testicles in multifocal form causing microcalcifications. A 28-year-old male visited our hospital with left testis pain. Physical examination of the scrotum revealed that both testicles were normal sized with no palpable mass. Ultrasonography evaluation revealed grade 3 left varicocele and an incidental 9 mm calcified mass in the right testicle, which was further confirmed by MRI. Partial orchiectomy was performed. Clinical data, radiological studies, and morphological and immunohistochemical characteristics were analyzed.

  • The Culture of Herbal Preparations Among Pregnant Women: A Remedy or a
           Suicide Potion' A Case Report and Mini Review

    • Abstract: In general, use of herbal remedies and preparations is on the ascendency in recent times among the general population and especially in young pregnant women, and this may be very dangerous due to adverse effects and interactions with drugs. A survey by the World Health Organization revealed that 70–80% of the world population resort to nonconventional medicines especially, herbal medicines in their primary healthcare. A lot of work has been done on the positive effects of herbs on the human body but very few publications on the potential side effects of consuming crude herbal preparations especially among pregnant women or the awareness of the medical team of this problem. Herbal remedies may come with many adverse effects and potentially serious interactions with some conventional medications. However, little is known about the dangers associated with consumption of herbal remedies by pregnant patients. Herbal medicines like their orthodox counterparts act through some mechanisms to bring about their curative effects in the body, and this usually goes out of order when these remedies interact with chemical drugs as a result of a combination of both by the victims. This is a case study to review the use of herbal medicine products among pregnant women, especially adolescent girls for abortive purposes, and also attempts to discuss some of the dangers associated with the use of herbal medicinal products together with conventional drugs during pregnancy.

  • Hypopharyngeal Dedifferentiated Liposarcoma in the MDM2 Era: A Case Report
           and Short Review

    • Abstract: Pharyngeal liposarcomas are very rare; still more rare are dedifferentiated liposarcomas in the pharynx. An 82-year-old man presented with dysphagia, voice changes, weight loss, nasal regurgitation of liquids, and coughing spells. A 3.5 cm mass was identified in the hypopharynx. The mass was biopsied and diagnosed as a benign fibroepithelial polyp. Continued symptoms and airway obstruction prompted a pharyngectomy, and the mass was then diagnosed as dedifferentiated liposarcoma. Due to infrequency and subtle histological findings, liposarcomas of the head and neck can be misdiagnosed and recur.

  • Distinguishing between HPV-Associated Metastatic Anal Squamous Cell Cancer
           and HPV-Associated Oropharyngeal Cancer

    • Abstract: The histology and immunohistochemistry (IHC) of primary and metastatic diseases from a human papilloma virus- (HPV-) related anal squamous carcinoma (ASCC) would typically demonstrate the same histology as an HPV-related oropharyngeal squamous carcinoma (OPSCC). However, determining whether a site of squamous cell carcinoma represents distant metastatic ASCC versus a metastatic HPV-related metastasis from an OPSCC to a regional lymph node carries profound prognostic and therapeutic implications. A patient with a history of locally advanced ASCC treated with standard concurrent radiation therapy and chemotherapy in 2015 is described. In 2018, an enlarged supraclavicular lymph node was excised demonstrating squamous cell carcinoma and radiographic staging revealed no other areas suspicious for malignancy. Direct laryngoscopy with operating telescope and biopsies demonstrated squamous cell carcinoma at the tongue base. Described here are assays that might be considered in distinguishing between whether a focus distant from a previously identified ASCC represents metastatic disease or instead a separate primary HPV-related cancer.

  • Metastatic Renal Cell Carcinoma to the Testis: A Clinicopathologic
           Analysis of Five Cases

    • Abstract: The testicular spread of renal cell carcinoma is extremely rare. Five cases of renal cell carcinoma metastatic to the testis are described. The patients ranged from 45 to 81 years of age. Four of the five patients had known renal cell carcinoma. The time intervals between the partial and radical nephrectomies for the primary kidney tumors and the occurrence of testicular metastases ranged from 29 to 34 months. In one patient, the testicular mass was the initial presentation leading to a diagnosis of renal cell carcinoma. There were three ipsilateral metastases, one contralateral metastasis, and one bilateral metastasis. The metastatic deposits ranged in size from 2.0 to 5.7 cm. One case had multiple metastatic tumor nodules. All of the metastatic tumors had clear cell histological features, microscopically concordant with the primary renal cell carcinoma subtype. Three patients died of the disease 17 to 42 months after orchiectomy. One patient is alive with additional metastatic lesions 13 months after orchiectomy. One patient had been free of disease at 87 months after orchiectomy but is now on targeted therapy for an additional metastasis at 93 months after orchiectomy. To date, this report is one of the largest single series of patients with renal cell carcinoma metastatic to the testis, and it has the longest follow-up and survival among all the reported cases.
