  • Follicular Bronchiolitis: Two Cases with Varying Clinical and Radiological

    • Abstract: Follicular bronchiolitis (FB) is a rare bronchiolar disorder associated with hyperplasia of the bronchial-associated lymphoid tissue (BALT). It is characterized by the development of lymphoid follicles with germinal centers in the walls of small airways. It falls under the category of lymphoproliferative pulmonary diseases (LPDs) and commonly occurs in relation to connective tissue disease, immunodeficiency, infections, interstitial lung disease (ILD), and inflammatory airway diseases. Computerized tomography (CT) findings include centrilobular nodules with patchy ground glass infiltrate, tree-in-bud findings, and air trapping. It can very rarely present as diffuse cystic lung disease. We present two cases of FB. The first case is associated with Human Immunodeficiency Virus (HIV) infection and asthma with diffuse cystic changes on the CT. The second case is associated with reactive airway disease and gastroesophageal reflux disease (GERD) with the classic centrilobular nodules and ground glass opacities on the CT.

  • Vaping Is Not Safe: A Case of Acute Eosinophilic Pneumonia following
           Cannabis Vapor Inhalation

    • Abstract: There is a well-established association between inhalational exposures and acute eosinophilic pneumonia (AEP). The most reported exposure is cigarette smoking. Here, we present a case of progressive shortness of breath and nonproductive cough in a college student with no significant medical history, approximately 10 days after inhaling cannabis aerosols on two separate occasions. He was started on empiric antibiotics and bronchodilators without improvement. He was diagnosed with AEP based on peripheral eosinophilia and high-resolution CT image results. He made rapid recovery on intravenous glucocorticoids. Vaping has gained popularity among young adults mainly due to the perception that it is a safe alternative to smoking. This case shows that there may be a false sense of security with vaping. Vaping poses a yet-to-be quantified public health threat, which requires further studies.

  • Spontaneous Hemopneumothorax: A Rare Cause of Unexplained Hemodynamic
           Instability in a Young Patient

    • Abstract: Spontaneous hemopneumothorax is a rare and potentially life-threatening disorder which complicates about 1-12% of patients presenting with spontaneous pneumothorax and has a remarkable predilection for male patients. It may present with signs of hypovolemic shock without apparent cause. While there are no specific guidelines for the management of patients diagnosed with such condition, wide debate in the literature relating to patient selection for surgery remains unresolved, and recently there seems to be a trend increasingly favorable towards early surgical intervention. Video-assisted thoracic surgery emerges as an excellent option for stable patients and has now been considered the gold standard treatment for spontaneous hemopneumothorax. We report the case of a 17-year-old male patient who presented to the emergency department with a history of sudden chest pain and dyspnea, with no previous evidence of trauma. On admission, the patient presented with hypotension, tachycardia, and cutaneous pallor. Chest X-ray showed hydropneumothorax on the left hemithorax; then, chest tube was placed with an initial drainage of 2000 ml of blood.

  • Goiter in a Patient with Pulmonary Arterial Hypertension Treated with

    • Abstract: A 35-year-old female with pulmonary arterial hypertension (PAH) who presented with complaints of progressively worsening dysphagia, facial swelling, and shortness of breath, was found to have a large goiter. In patients treated with epoprostenol for long periods of time, thyroid disease is common. Most cases of thyroid disease describe thyrotoxicosis and hyperthyroid statues, but our case was a patient on long term IV epoprostenol presenting with a superior vena cava-syndrome (SVC) like appearance and airway compromise found to have a goiter incidentally during workup.

  • Pulmonary Hyalinizing Granuloma Mimicking Primary Lung Cancer: An Unusual
           Case Involving a Pulmonary Tumor

    • Abstract: Pulmonary hyalinizing granuloma is a very rare benign condition. This study describes a case involving pulmonary hyalinizing granuloma in a 76-year-old man who presented with a solitary pulmonary nodule, determined through chest radiography and computed tomography, that mimicked primary lung cancer. To establish a definitive diagnosis, tumor resection was performed with histopathological analysis indicating pulmonary hyalinizing granuloma. Radiographic findings in previously reported cases showed that most patients had well-defined margins and usually bilateral, multiple lesions. In our case; however, the solitary ill-defined tumor mimicking lung cancer is an uncommon location for this rare condition.

  • Isolated Pauci-Immune Pulmonary Capillaritis Associated with Hydrocarbon
           Inhalation and Marijuana Smoking: An Unusual Case of Severe Hypoxemia

    • Abstract: We present a case report of a patient with Isolated pauci-immune pulmonary capillaritis (IPIPC). A 40-year-old male presented with acute onset severe hypoxemic respiratory failure. He had just returned home from work as a cabinetmaker, where he experienced inhalational exposure to hydrocarbons and solvents, and had smoked a marijuana cigarette. He was hypotensive, and his chest imaging showed bilateral dependent infiltrates. His hypoxemia made little improvement after conventional ventilator support and broad-spectrum antibacterial therapy and he was considered too unstable to tolerate diagnostic bronchoscopy with bronchoalveolar lavage. His laboratory evaluation initially showed microscopic hematuria which later cleared, but other tests including serologic autoimmune assessment were negative, and he did not have any traditional risk factors for vasculitis. A video-assisted thoracoscopic lung biopsy revealed diffuse alveolar hemorrhage with pulmonary capillaritis on histopathology. He was diagnosed with IPIPC and initiated on immunosuppressive therapy. He was soon liberated from mechanical ventilation and improved to hospital discharge. Diffuse alveolar hemorrhage from Goodpasture’s Syndrome has manifested following inhalation of hydrocarbons and following smoking. This has not previously been reported with IPIPC. Given the lack of other findings and risk factors, his IPIPC was likely associated with occupational exposures to hydrocarbons as a cabinetmaker compounded by marijuana smoking.

  • A Case of Vaping TCH Oil Leading to Vaping Associated Pulmonary Injury:
           Our Approach to Its Diagnosis, Management, and Recommendations

    • Abstract: Vaping’s popularity has grown exponentially since its introduction to the US market in 2003. Its use has sky-rocketed since the unveiling of the vaping pods in 2017 which may account for the advent of the vaping related illnesses we are now seeing. Substances such as nicotine solution, tetrahydrocannabinol (THC) oil, cannabidiol (CBD) oil, and butane hash oil (BHC) packaged in cartridges available in various flavors and concentrations are aerosolized by the heating of metal coils in the e-cigarette/vaping devices. Cases from all over the country have recently been coming to light in which vaping has led to severe acute pulmonary disease or vaping-associated-pulmonary-injury (VAPI). A vast majority of the presenting patients in the reported cases have required hospitalization and intensive care, needing supplemental oxygen and even endotracheal intubation and mechanical ventilation. 98% of patients present with respiratory symptoms (dyspnea, hypoxia, chest pain, cough, hemoptysis), 81% of patients have gastrointestinal symptoms (nausea, vomiting, diarrhea, and abdominal pain), and 100% of patients have constitutional symptoms such as fever, chills, and fatigue/malaise on presentation. Although based on history and clinical presentation it is reasonable to have a high suspicion for VAPI, diagnostic workup to rule out alternative underlying causes such as infection, malignancy, or autoimmune process should be performed before establishing the diagnosis. Computed Tomography (CT) scans of the chest have predominantly shown ground-glass opacity in the lungs, often with areas of lobular or subpleural sparing. Although lung biopsies have been performed on a relatively low number of cases, lung injury patterns so far have shown acute fibrinous pneumonitis, diffuse alveolar hemorrhage, or organizing pneumonia, usually bronchiolocentric, and accompanied by bronchiolitis. Treatment plans that have led to clinical improvement in the reported cases center around high-dose systemic steroids, although there are a lack of data regarding the best regimen and the absolute need for corticosteroids. The role of antibiotics appears to be limited once infection has definitively been ruled out. We present the case of a young male who vaped THC oil and developed severe acute pulmonary injury requiring mechanical ventilation and showed a remarkable response to high dose steroid therapy with improvement in clinical symptoms and resolution of diffuse ground glass opacity on repeat HRCT scan.

  • Cryptogenic Organizing Pneumonia with a Rare Radiographic Presentation of
           a Diffuse Micronodular Pattern Mimicking Miliary Lung Infiltration: A Case
           Report and Review of the Literature

    • Abstract: We reported a case of cryptogenic organizing pneumonia (COP) presenting with an unusual diffuse micronodular pattern (DMP) mimicking miliary lung infiltration. The patient is a 66-year-old man with a past medical history of diabetes mellitus type 2 and hyperlipidemia who presented with progressive dyspnea associated with significant weight loss and night sweats for 2 weeks. Upon admission, the patient’s clinical condition rapidly progressed to respiratory failure requiring mechanical ventilation. Initial Chest X-ray (CXR) showed diffuse reticulonodular infiltration mimicking miliary pattern. Chest computed tomography (CT) showed diffuse centrilobular micronodular infiltrations with features of a tree-in-bud pattern consistent with the CXR findings. He was then started on empiric antibiotics for community-acquired pneumonia and underwent a diagnostic bronchoscopy with alveolar lavage and transbronchial biopsies, which yielded negative cultures and unrevealing pathology. Tissue from CT-guided lung biopsy performed later on was also inconclusive. Due to the lack of clinical improvement, he eventually underwent surgical lung biopsy. The pathology result showed organizing pneumonia (OP) pattern with heavy lymphoplasmacytic infiltrates and numerous multinucleated giant cells. His final culture results, microbiological data and serology workup for autoimmune disease were all unremarkable. The patient was diagnosed with COP and was started on systemic corticosteroids. He displayed dramatic clinical improvement and was successfully liberated from the ventilator. Subsequent chest imaging showed resolution of the reticulonodular infiltrations. Early diagnosis for OP and ability to distinguish OP from infectious pneumonitides are critical as the majority of patients with OP respond promptly to corticosteroids. Common findings of radiographic pattern for OP are patchy air space consolidation or ground-glass opacity, yet DMP is another rare radiographic pattern that must be recognized, especially in COP. In summary, this case illustrates a rare radiographic presentation of COP. With early recognition and prompt diagnosis, proper treatment can significantly prevent morbidity and reduce mortality.

  • Successful Treatment for Hypercalcemia due to Cosecretion of Parathyroid
           Hormone-Related Protein and 1,25-Dihydroxyvitamin D3 in Non-Small-Cell
           Lung Cancer: A Case Report and Literature Review

    • Abstract: Hypercalcemia of malignancy frequently manifests as paraneoplastic syndrome in patients with solid tumors. A 71-year-old man was diagnosed with stage IIIB lung squamous cell carcinoma. Laboratory examination revealed high serum calcium concentration with elevated serum parathyroid hormone-related protein (PTHrP) and 1,25-dihydroxyvitamin D3 levels. As the patient did not respond to the initial treatment with calcitonin, extracellular fluid infusion, and chemotherapy, systemic prednisolone was administered additionally. Thus, the levels of serum calcium normalized and PTHrP and 1,25-dihydroxyvitamin D3 decreased simultaneously. To our knowledge, this is the first case report on the successful treatment of hypercalcemia of malignancy caused by PTHrP and 1,25-dihydroxyvitamin D3 cosecretion in a patient with lung cancer.

  • Cicatricial Organizing Pneumonia with Dendriform Pulmonary Ossification:
           An Unusual Cause for a Recurrent Pneumothorax

    • Abstract: Cicatricial organizing pneumonia is an uncommon form of organizing pneumonia, which may manifest as persisting linear opacities on computerized tomography (CT) scan mimicking a fibrosing interstitial pneumonia. It may also manifest with pulmonary ossification, which is a metaplastic bone formation within the lung tissue. The latter presentation could be either nodular or dendriform, both secondary to underlying lung disease and rarely idiopathic. Dendriform pulmonary ossification (DPO) has rarely been described as a cause of spontaneous pneumothorax. We present a case of a 55-year-old male with history of recurrent pneumothoraces and worsening dyspnea on exertion. A CT of the chest revealed progressive bilateral sub-pleural and peribronchovascular reticular opacities associated with densely ossified branching and nodular opacities. Video-assisted thoracoscopic biopsy of the lung demonstrated cicatricial organizing pneumonia with areas of marked diffuse DPO. The case highlights that dendriform pulmonary ossification arising from cicatricial organizing pneumonia should be considered in the differential diagnosis of recurrent pneumonias among patients with lower lobe sub-pleural reticular opacities. The case highlights that dendriform pulmonary ossification rarely can cause spontaneous pneumothorax and can be associated with cicatricial organizing pneumonia and reticular opacities on imaging.

  • Hypersensitivity Pneumonitis Associated with Red-Vented Bulbul: A New
           Encounter of Bird Related Hypersensitivity Pneumonitis

    • Abstract: Bird related hypersensitivity pneumonitis (HP) is becoming more common than other forms of HP around the world. We present two cases of HP, associated with exposure to visiting birds which had nested within their homes in semi urban areas of Colombo, Sri Lanka. A 65-year-old female (case 1) and a 61-year-old male (case 2) presented to the chest clinic complaining of gradually progressive and persistent chronic dry cough and dyspnoea during the year 2018. Both were found to have close contact with red-vented bulbuls (Konda kurulla) in their homes for more than 6 months prior to onset of symptoms and denied any other risk exposures in detail history taking. In both patients, high-resolution computed tomography chest (HRCT) showed centrilobular nodules of ground glass density with significant lobular air trapping. Video-assisted thoracoscopic (VATs) lung biopsy of case 1 showed patchy and focal interstitial thickening with lymphocytic infiltrate, minimal fibrosis, and few noncaseating granulomata within the interstitium. Transbronchial lung biopsy of case 2 showed thickened alveolar septae with lympho-histiocytic infiltrate and occasional neutrophils and eosinopils. Both showed severe reduction in forced vital capacity (FVC) at presentation. Multidisciplinary diagnosis of HP associated with red-vented bulbuls was made. Both achieved good improvement in clinical, lung function, and radiological assessment following removal of offending antigen exposure and treatment with oral corticosteroids.

  • A Case of Isolated Primary Pleural Neurofibroma in a 39-Year-Old Woman

    • Abstract: Primary benign neurogenic neoplasms of the pleura are exceedingly rare. Neurofibromas rarely involve the pleura. A review of the literarture reveals only a single reported case of isolated pleural neurofibroma. Herein the authors describe another case of isolated primary pleural neurofibroma. A 39-year-old nonsmoker woman presented to the emergency room with complaints of progressively worsening chest pain of one month duration. A computed tomography of the chest revealed a crescent shaped, pleural based mass suspicious for a neurogenic tumor such as an intercostal schwannoma. A PET-CT skull base to midthigh failed to reveal any other masses or abnormalities. A surgical excision of the mass was performed due to the patient’s intractable pain. The resected specimen consisted of an ovoid fragment of soft tissue with pale yellow, smooth and glistening cut surface. Microscopic examination revealed the tumor to be composed of spindle cells with wavy nuclei arranged haphazardly in loose collagenous and pale myxoid stroma with rare interspersed mast cells. The spindle cells were diffusely positive for S100 protein and SOX-10, and focally positive for neurofilament. In the absence of any other masses in the patient and no pertinent history, a diagnosis of primary pleural neurofibroma was made. This case emphasizes the need to consider neurofibroma in any spindle cell neoplasm of the pleura irrespective of age or singularity.

  • Solitary Pulmonary Nodule: A Diagnostic Dilemma

    • Abstract: This case describes a woman with a history of tobacco abuse who presented with a dry cough and was found to have an enlarging, 4 cm right upper lobe nodule without lymphadenopathy on CT imaging of the chest. Initial biopsies of the nodule suggested follicular lymphoma, but after obtaining more tissue, the pathology was negative for malignancy and instead showed necrotizing pneumonia. She proceeded to have negative infectious serology and cultures. She had negative rheumatological testing including MPO ANCA, PR-3 ANCA, and rheumatoid factor. She did not have renal failure, hemoptysis, weight loss, arthralgia, or upper airway inflammation. She ultimately underwent a right upper lobectomy, as the nodule was enlarging on repeat imaging. The pathology of the lung showed necrotizing granulomas with giant cells and fibrosis, but lacked active vasculitis or palisading histiocytes, further obscuring the diagnosis. She was conservatively managed with intranasal steroids, cough suppressants and antihistamines given her lack of severe symptoms. The diagnosis was most consistent with granulomatosis with polyangiitis (GPA) presenting as a solitary pulmonary nodule with pathology reflecting a mild degree of disease activity. The patient may manifest further signs of the disease while being monitored clinically.

  • A Rare Case of Bronchial Anthracofibrosis with Pleural Anthracosis
           Presented as Recurrent Pleural Effusion

    • Abstract: A fifty-eight-year-old, nonsmoker Indian male presented with recurrent left pleural effusion. He had history of dry cough, exertional breathlessness for the last two years. He denied any occupational exposure or second hand smoke exposure. His physical examination demonstrated decreased breath sounds on the left side of chest. Cardiac evaluation was unremarkable. Diagnostic pleural aspiration revealed straw coloured fluid, exudative, and nonmalignant in nature. CT-imaging of the chest demonstrated left pleural effusion, nodular parenchymal infiltrates in bilateral lungs, plate like atelectasis in the left lower lobe. Bronchoscopy showed diffuse airway pigmentation, right middle lobe opening, and left lower lobe bronchus pigmented and stenosed. Semi-rigid pleuro-videoscopy revealed diffuse black coloured deposits over visceral pleura and focally scattered deposits over parietal pleura. Spirometry showed mild airway obstruction with moderate impairment in diffusion capacity.

  • Severe and Fatal Multilobar Nonclassic Radiation Pneumonitis following
           Stereotactic Body Radiation Therapy (SBRT) for Treatment of Inoperable
           Non-Small-Cell Lung Cancer: A Report of Two Cases and Possible Enhancement
           by Concurrent Amiodarone

    • Abstract: Stereotactic body radiation therapy (SBRT) is considered the standard of care for treatment of inoperable early stage non-small cell carcinoma of the lung. SBRT delivers a very high dose of ionizing radiation to a relatively small region encompassing the tumor and spares a significant portion of the remaining lung from high doses. However, the conformal high dose comes at the expense of treating a larger volume of normal lung to lower doses. In general, this has been deemed to be acceptable with an overall lower risk of radiation pneumonitis. However, in the face of predisposing factors, the higher doses delivered by this technique may lead to an increase in radiation pneumonitis. We report on two patients being treated with SBRT in which severe radiation pneumonitis developed in spite of our radiation dosimetry being significantly below the acceptable limit for lung toxicity. Both patients developed a “fulminant” form of radiation pneumonitis with radiographic abnormalities well beyond the treated volume. In one patient, the disease proved fatal. Both patients were on amiodarone at the time SBRT was administered. Given the rarity of fulminant radiation pneumonitis, especially with the relatively small fields treated by SBRT, we suspect that amiodarone enhanced the pulmonary toxicity.

  • A Rare Case of Hypersensitivity Pneumonitis due to Florida Red Tide

    • Abstract: Florida red tides occur annually due to proliferation of the marine dinoflagellate Karenia brevis, which produces neurotoxins known as brevotoxins. Inhalational exposure to brevotoxins usually results in upper airway symptoms only. Rarely does exposure lead to lower respiratory tract symptoms as in our case. We report a case of a 50-year-old man who presented with a 4-week history of dyspnea after exposure to the red tide. Computed tomography (CT) of the chest showed diffuse bilateral ground glass opacities and interstitial thickening. Bronchoalveolar lavage cultures and cytology were negative. The patient was started on steroids. Over the next few weeks, the patient’s symptoms resolved. Repeat CT chest showed complete resolution of the ground glass opacities. Steroids were then tapered. Most patients who are exposed to algal blooms have self-limiting symptoms. Patients with asthma are particularly susceptible to worsening respiratory symptoms after exposure to brevotoxin aerosols. This case highlights that, in rare cases, exposure to red tide can results in severe lower respiratory tract symptoms.

  • Chylothorax and Chylopericardium: A Complication of Long-Term Central
           Venous Catheter Use

    • Abstract: The development of chylothorax and chylopericardium is an uncommon complication of the long-term use of central venous catheters. We describe a unique case of an end stage renal disease patient on hemodialysis with a left jugular tunneled catheter who developed superior vena cava syndrome. Our patient presented with both a large pleural and pericardial effusion that despite drainage continued to reaccumulate. Further imaging with CT scan of the thorax revealed stenosis of the superior vena cava leading to recurrent chylothorax and chylopericardium.

  • An Unusual Cause of Spontaneous Pneumomediastinum: The Mounier-Kuhn

    • Abstract: Mounier-Kuhn syndrome is a rare clinical and radiologic condition. It is characterized by tracheal and bronchial dilation. Diagnosis is made by computed tomography and bronchoscopy. An 81-year-old man presenting with an acute chest pain was referred to the pulmonology department. His chest computed tomographic scan showed a tracheobronchomegaly with an increase in the diameter of both the trachea and right and left main bronchi, associated with pneumomediastinum and fibrosis. Fiberoptic bronchoscopy revealed enlarged trachea and both main bronchi. These findings are consistent with a diagnosis of Mounier-Kuhn syndrome. Besides considering this long-neglected “orphan disease” when diagnosing spontaneous pneumomediastinum, clinicians should also be aware of an underlying Mounier-Kuhn syndrome in patients with recurrent respiratory infections, in order to avoid complications associated with the disease.

  • Bilateral Chylothorax as a Unique Presentation of Pancreaticobiliary or
           Upper Gastrointestinal Cancer

    • Abstract: Chylothorax presents as exudate with lymphocytic predominance and high triglyceride-low LDH levels, usually due to a traumatic disruption of the thoracic duct, possibly iatrogenic. Other causes include malignancy, sarcoidosis, goiter, AIDS, or tuberculosis. Here we present a case of a 66-year-old male who came in with cough and shortness of breath for few weeks. A week earlier, at an ED visit, he was diagnosed with pneumonia based on CT angiogram of the chest without contrast that showed bilateral pleural effusion and bilateral pulmonary infiltrates. The CT-guided placement of bilateral chest tube drained 1160 cc of creamy yellow fluid on the right and 1200 cc of creamy yellow fluid on the left. CT chestabdomenpelvis showed bilateral ground-glass opacities within the lungs and possible bony metastasis. A whole-body bone scan showed multiple bony metastatic lesions throughout the skeleton. IR guided bone biopsy suggested upper GI or pancreaticobiliary cancer. Venous ultrasound with Doppler of left upper extremity showed findings suggestive of a nonocclusive DVT of proximalmid left subclavian vein which is difficult to compress. Eventually, malignancy-related DVT of the left subclavianbrachiocephalic vein was identified as the possible etiology for the bilateral chylothorax.

  • Case Report: Kryptonite—A Rare Case of Left-Sided Bilothorax in a
           Sickle Cell Patient

    • Abstract: Bilothorax is a rare cause of an exudative pleural effusion. The diagnosis is confirmed by a pleural fluid to serum bilirubin ratio of greater than 1. Typically, bilothorax presents as a right-sided effusion due to its proximity to the liver and biliary system. Herein, we present a case of isolated left-sided bilothorax in a 43-year-old female admitted with sickle cell crisis. Only one other case of isolated spontaneous left-sided bilothorax has been described in the literature. A thoracentesis performed on admission demonstrated greenish fluid and bilothorax was suspected, with a pleural fluid to serum bilirubin ratio greater than 1 confirming the diagnosis. A magnetic resonance cholangiopancreatography (MRCP) showed an abnormal 90-degree acute angulation in the mid-to-distal common bile duct with proximal common bile duct and intrahepatic bile ducts dilation. This was further confirmed with an endoscopic retrograde cholangiopancreatography (ERCP), which did not reveal any extravasation of contrast into the left pleural space. Ultimately, despite the use of various modalities, no definitive cause of bilothorax was identified. Postthoracentesis imaging revealed evidence of fibrothorax, a direct and permanent complication of bilothorax. The presence of an isolated left-sided bilothorax, along with the lack of a confirmed etiology, makes this case unique.

  • Large Spontaneous Right Catamenial Pneumothorax with Diaphragmatic Defect
           and Liver Herniation

    • Abstract: Catamenial pneumothorax is a spontaneous pneumothorax that occurs predominantly women of child bearing age. We describe a case of a 40-year-old nulliparous woman with medical history significant for endometriosis who presented with severe chest tightness of one-day duration. Chest radiography (CXR) showed a large right spontaneous pneumothorax, what was thought to be a 5.6 cm pleural mass at the right lung base. Following pneumothorax diagnosis, the patient underwent emergent right thoracostomy with pigtail catheter placement. A repeat CXR revealed marked re-expansion of the lung but persistence of a right pleural mass. Follow up computed tomography scan of the chest showed a 33 mm diaphragmatic defect with 5.8 x 4.6 x 3.9 cm area of herniated liver corresponding to the presumed pleural mass. Following complete thoracic imaging, patient underwent video-assisted thoracoscopic surgery, mechanical pleurodesis, and open repair of the right diaphragmatic defect. Intraoperatively, an endometrial implant was noted on the chest wall. On postoperative day three, she began her menstrual cycle and was evaluated by gynecologist who recommended hormonal therapy to reduce risk of recurrent pneumothorax. Due to a persistent air leak, the chest tube was transitioned to a Heimlich valve to facilitate home discharge. The patient was discharged on postoperative day eight, seen as outpatient with resolution of air leak and removal of chest tube.

  • Saddle Pulmonary Embolus Caught in Transit across a Patent Foramen Ovale

    • Abstract: Impending paradoxical embolism (IPE) also described in the literature as thrombus straddling a patent foramen ovale (PFO) or paradoxical embolus in transit is a rare condition when thrombus (originating mostly in deep veins of lower extremities) embolized to the heart gets caught in PFO or in atrial septal defect without systemic embolization. We present a case of a 39-year-old female on oral contraceptive pills who presented to the emergency department with chief complaint of dyspnea and chest pain. She was found to have saddle pulmonary embolus (PE) extending through PFO to left atrium and into the left ventricle. Patient underwent emergent open pulmonary embolectomy, removal of right and left atrial thrombi, and closure of patent foramen ovale. She tolerated the surgery well and was discharged home on chronic anticoagulation therapy.

  • Osseous Sarcoma: Is Sarcoma the New Emperor of Maladies' Case-Series
           with Brief Review of the Literature

    • Abstract: Sarcoidosis is multisystem disease that has been amusing physicians since its discovery in 1989 by Caesar Boeck. More than 10,000 articles have been published in the literature by far, and each time it affects a new organ. Involvement of bone has been recently discovered and because it is still a rare entity, it is important to focus on the presenting systems and also to be able to differentiate it from other closely related diseases including but not limited to tumor and other infectious processes. We describe two cases of osseous sarcoma in two relatively young but surprisingly asymptomatic patients.

  • Primary Pulmonary Malignant Melanoma Found While Evaluating New Onset
           Cough: A Case Presentation and Literature Review

    • Abstract: Malignant melanoma is a nonepithelial neoplasm of melanocytes. It is tremendously rare for this condition to primarily involve the respiratory tract, accounting only for 0.01% of the lung malignancies. It often presents as a solitary nodule provoking mass effect and/or obstructive symptom. It most commonly affects patients 50 years old and older, with no gender predilection. Complete surgical excision is the treatment of choice; nevertheless, chemotherapy or radiation might be necessary depending on tumor location and/or metastasis status. Recently, biochemotherapy and immunotherapy have emerged as promising treatment modalities. We present a case of Primary Pulmonary Malignant Melanoma (PPMM) in a 76-year-old male with no previous personal or family history of cancer who presented with new onset nonproductive cough. We also present an analysis with high yield points summarizing clinical features, diagnostic workup, and management of PPMM. Finally, we post a table summarizing all the cases ever reported in English literature.

    • Abstract: Pulmonary malignancies carry a significant morbidity and mortality and are one of the leading causes of cancer-related deaths worldwide. Primary pulmonary lymphoma is a rare malignancy which should be considered in the differential of solitary pulmonary nodule or lung mass especially in a low-risk patient presenting with constitutional symptoms. Here, we describe a case of an elderly male who presented to our clinic with incidental pulmonary nodules and subsequent workup revealed low grade B cell non-Hodgkin's lymphoma consistent with diagnosis of primary pulmonary marginal zone lymphoma.

  • Pneumocystis jirovecii Pneumonia in an Immunocompetent Japanese Man: A
           Case Report and Literature Review

    • Abstract: We herein report the case of a 37-year-old immunocompetent man who died from Pneumocystis jirovecii pneumonia (PCP). He was initially treated for an acute exacerbation of interstitial pneumonia; however, the elevation of the patient’s serum (1-3) β-D glucan (BG) level suggested the possibility of PCP and sulfamethoxazole trimethoprim was added. A postmortem pathological examination and retrospective Grocott's methenamine silver (GMS) staining of the bronchoalveolar lavage fluid (BALF), which was obtained on the day of admission, revealed PCP. The present case suggests that it is essential to perform a BG assay and GMS staining of BALF specimens when patients show diffuse ground-glass opacity on chest computed tomography, regardless of their immune status.

  • A Woman with Asthma and Peripheral Ground-Glass Opacities

    • Abstract: Eosinophilic lung disease is a heterogeneous group of disorders that reveal eosinophil involved lung tissue often in patients with asthma or atopy. Classification and diagnostic criteria of eosinophilic lung disease are not well-established; however, peripheral ground-glass opacity is typical on chest computed tomography. Another etiology of this same radiographic finding reported in the literature is silicone embolism syndrome. Here, we present a 43-year-old female with poorly controlled severe persistent asthma presenting with difficulty breathing. Computed tomography showed peripherally dominant ground-glass opacity. Peripheral blood, bronchoalveolar lavage fluid analysis, and transbronchial biopsy did not find eosinophilia. Serial bronchoalveolar lavage of the demonstrated increasingly blood-tinged fluid. The patient required mechanical ventilation upon admission. After further questioning the patient revealed that she had frequently received injectable cosmetics at non-licensed establishments. Initially, due to past medical history, presentation, and radiographic findings, eosinophilic pneumonia was suspected. However, after a review of the patient’s social history and risk factors, silicone embolisms syndrome became a likely diagnosis. The patient had good clinical response to high dose steroid therapy.

           Approach for a Challenging Middle Lobectomy in an Obese Patient

    • Abstract: Subcostal access is a novel approach for anatomical lung resection. To perform surgery via this access, specially designed long instruments are required. Subcostal access provides excellent visualization of the mediastinum and anterior lung hilum. We exhibit here a subcostal middle lobectomy with systematic en-block mediastinal lymphadenectomy in an obese 52-year-old male patient with body mass index (BMI=37.7) performed via this single incision. The operation was completed efficiently within 30 minutes with negligible postoperative pain.
