    ABSTRACT: Solitary fibrous tumors are rare neoplasms of mesenchymal origin. They are often of low malignant potential and rarely metastasize. While they frequently arise from the pleura, they can occur at any soft tissue site in the body. We present a case of a large (28 × 21cm) malignant solitary fibrous tumor arising from the bladder serosa. In addition, the clinicopathologic features, differential diagnosis, cytogenetics and management of this rare disease are discussed, along with a review of the existing literature on this topic. An otherwise healthy 41-year-old Caucasian man presented with weight loss and progressive abdominal bloating. A subsequent computed tomography scan of his chest, abdomen and pelvis revealed a 26.8 × 21cm intra-abdominal mass occupying most of his abdominal cavity. The inferior vena cava was compressed, and the mass extended inferiorly to his upper pelvis abutting the superior dome of his bladder. He underwent operative resection and the resected mass measured 28 × 21 × 18cm and weighed 4.8kg. The cut surface revealed a gray-white mass with an ill-defined whorled-like pattern, with randomly assorted tan fleshy nodules. A histologic evaluation revealed variable, alternating hypercellular and hypocellular areas, with areas of necrosis. The tumor cells varied from spindle to epithelioid within a hyalinized stroma. In the hypercellular areas, the tumor cells showed moderate atypia with high mitotic activity. The histological features combined with immunophenotyping were suggestive of a malignant solitary fibrous tumor that grossly appeared to be growing from the bladder serosa, specifically the intraperitoneal superior dome of the bladder. Our patient is currently eight months post-surgery without evidence of recurrence. Extrapleural occurrences of solitary fibrosis tumors are being increasingly observed. Malignant solitary fibrosis tumors of the urinary bladder, however, are very rare. As there are no pathognomonic features of malignancy, surgical resection is often both diagnostic and therapeutic, as was the case in our report.

    ABSTRACT: Contributing reviewers A peer-reviewed journal would not survive without the generous time and insightful comments of the reviewers, whose efforts often go unrecognized. Although final decisions are always editorial, they are greatly facilitated by the deeper technical knowledge, scientific insights, understanding of social consequences, and passion that reviewers bring to our deliberations. For these reasons, the Editor-in-Chief and staff of the journal warmly thank the 906 reviewers whose comments helped to shape Journal of Medical Case Reports, for their invaluable assistance with review of manuscripts for the journal in Volume 8 (2014).

    ABSTRACT: Pyomyositis, though classically considered a tropical disease, has a variable geographic prevalence. Among the predisposing risk factors, immunodeficiency plays an important role. Pyomyositis has a tendency to mimic more commonly considered diseases, and a lack of familiarity with it is a cause of delayed diagnosis. A 53-year-old South Asian man with newly diagnosed type 2 diabetes mellitus was referred to our medical unit in an advanced stage of the disease, which was complicated by sepsis and acute kidney injury. Failure of the referring unit to provide prompt treatment, as well as their delay in coming to a diagnosis, led to the patient's complicated state. Antibiotic therapy was initiated, and clinical stabilization was achieved with supportive measures. Following the patient's recovery from sepsis, his persistent leukopenia and anemia was suggestive of an underlying immunodeficiency, and a subsequent bone marrow biopsy revealed acute myeloid leukemia, M2 variant. Multi-disciplinary care was initiated by the medical, surgical and oncological teams. Awareness of tropical pyomyositis is lacking. Common predisposing behaviors and conditions should always be sought and investigated. Immunosuppressive state is an important predisposing factor in the pathogenesis of pyomyositis. Early antibiotic treatment is pivotal in management, and surgical intervention, when relevant, should not be delayed. Identifying one cause should not halt the search for others, as pyomyositis may herald underlying sinister diseases.

    ABSTRACT: Esophagogastric varices bleeding is a common complication due to portal hypertension in patients with liver cirrhosis. With the advancement of nonoperative management including vasoactive agents, endoscopic hemostasis or transjugular intrahepatic portosystemic shunt, surgical management has played a lesser role in recent decades. The present report describes a patient with hepatitis B (HBV)-related liver cirrhosis and portal vein thrombosis with recurrent esophagogastric varices bleeding despite the use of medical and endoscopic therapy. The modified Sugiura procedure was performed as an alternative bridge surgery for liver transplantation in order not to change the anatomic structure of the great vessels and to avoid hepatic encephalopathy related to shunting procedures like the transjugular intrahepatic portosystemic shunt. A 56-year-old Chinese man with a history of portal hypertension due to HBV-related liver cirrhosis and known former recurrent esophageal varices bleeding status post Sengstaken-Blakemore tube tamponade was referred to our hospital for liver transplantation evaluation because of persistent esophagogastric varices bleeding with hypovolemic shock, even after medical and endoscopic therapies in a local hospital. As a result, liver cirrhosis with Child-Pugh class B function was diagnosed. Despite the use of vasoactive agents, and endoscopic hemostasis management, esophagogastric varices bleeding still occurred episodically with hypovolemic shock, which could not be reversed by blood transfusion or Sengstaken-Blakemore tube tamponade. The modified Sugiura procedure, as an alternative bridge therapy for patients who are candidates for liver transplantation, was performed, despite the fact that his liver transplantation was not yet completed. He then received a living donor liver transplantation with the right lobe of liver from his daughter. The postoperative course was uneventful, and he was discharged two weeks later. He had no evidence of recurrent esophagogastric varices bleeding during the six-month follow-up. The treatment experience of this case gave us not only the idea but also the practical way of applying the modified Sugiura operation as a bridge and rescue therapy without alteration of the vascular anatomy and hemodynamic stability for patients who have experienced refractory esophagogastric varices bleeding, despite the use of medication and endoscopic treatment, and are candidates for receiving a liver transplantation.

    ABSTRACT: Entrapped thrombus in a patent foramen ovale is a rare form of right heart thromboembolism. Various treatments have been used, such as anti-coagulation and thrombolytic therapy, vena cava filter, percutaneous thrombectomy and surgical embolectomy. A 60-year-old Kosovan woman was admitted to our hospital with a massive bilateral pulmonary thromboembolism, entrapped thrombus in the patent foramen ovale and severe right ventricular dysfunction. The patient underwent on-pump beating-heart removal of the intracardiac thrombus and bilateral pulmonary embolectomy with the use of a Fogarty catheter. The patient's post-operative course was uneventful. In this report, we describe for the first time in this pathology, to the best of our knowledge, a surgical strategy that seems to offer an excellent outcome in patients with severe right ventricular dysfunction. The chosen surgical technique, consisting of on-pump open beating-heart surgery, is a unique procedure in the treatment of an acute pulmonary thromboembolism and entrapped thrombus in a patent foramen ovale.

    ABSTRACT: Emphysematous cystitis is a very rare complicated urinary tract infection characterized by air in the bladder wall. We report two clinical cases of emphysematous cystitis of an 83-year-old Caucasian woman with diabetes mellitus and a 78-year-old Caucasian man with no past medical history. They presented with severe confusion and abdominal distension. Emphysematous cystitis was diagnosed in time with a thorough physical examination, urine analysis and computed tomography. The patients were successfully treated with antibiotic therapy and bladder drainage. This rare disorder should be recognized in time and treated properly to guarantee survival.

    ABSTRACT: The gross majority of extramedullary plasmacytomas arise in the lymphatic tissue of the upper respiratory tract. On average, one third of patients with a solid plasmacytoma will develop multiple myeloma, resulting in a worse clinical outcome. We describe a case of rapid recurrent extramedullary plasmacytomas in the background of an asymptomatic multiple myeloma. A 71-year-old, white Caucasian woman presented with three extramedullary plasmacytomas occurring within a short time period. The third plasmacytoma was accompanied by progressive cervical pain and swallow dysfunction. Additional immunostaining test results were negative for CD56 and showed high MIB-1 expression in the extramedullary plasmacytoma and low MIB-1 expression in the bone marrow. A conventional swallow X-ray did not show any obstruction, however a magnetic resonance imaging scan of her cervical backbone revealed an extramedullary plasmacytoma, threatening her spinal cord. A short course of radiation therapy alleviated her pain and during almost a two-year follow-up period, the multiple myeloma remained asymptomatic, despite the rise in immunoglobulin A lambda levels. After the appearance of the third plasmacytoma, systemic chemotherapy was started to prevent the development of a fourth plasmacytoma, despite the asymptomatic character of the multiple myeloma. In this case report we describe the rapid appearance of extramedullary plasmacytomas in the background of an asymptomatic multiple myeloma. An immunohistochemical analysis was negative for CD56 and showed high MIB-1 expression in the extramedullary plasmacytoma and low MIB-1 expression in the bone marrow, contributing to the potential underlying pathophysiology of the recurrent extramedullary plasmacytomas and their genetic changes. Systemic chemotherapy was started and no fourth extramedullary plasmacytoma has developed since.

    ABSTRACT: Nephrotic syndrome is considered a rare cause of chylous ascites. Intestinal lymphangiectasia in a background of chylous ascites and without any lymphatic obstruction has been reported in association with yellow nail syndrome, which is a rare clinical occurrence in itself. The existence of chylous ascites, duodenal and splenic lymphangiectasia (without any lymphatic obstruction) and nephrotic syndrome in the form of focal segmental glomerulosclerosis in the same patient makes this case the first of its kind to be reported in the literature. Here we report the case of a 54-year-old Asian man who presented with recurrent episodes of anasarca for approximately 25 years. He was subsequently found to have chylous ascites, lymphangiectasia and persistent proteinuria. A renal biopsy revealed focal segmental glomerulosclerosis, not otherwise specified. A lymphangiogram, which was performed with the purpose of addressing the intestinal lymphangiectasia, failed to demonstrate any abnormality of lymphatic channels. He was put on oral steroids with consequent remission of his oedema and proteinuria. This case highlights the fact that duodenal and splenic lymphangiectasia can exist in a scenario of chylous ascites without any obvious obstruction of lymphatic channels and in the absence of yellow nail syndrome. This case also signifies that chylous ascites may be a rare presenting feature of nephrotic syndrome and hence this aspect should be considered while in diagnostic dilemma regarding such a clinical presentation.

    ABSTRACT: Typical aura without headache (TAWH), which has been rarely reported both at home and abroad, is a rare type of migraine with aura. This is a report on a 64-year-old Chinese migraineur who has had recurrent typical visual aura without headache attacks for more than 30 years, and has been misdiagnosed as having had transient ischemic attacks (TIA) many times. He mainly experienced episodes of 'homonymous blurred vision' or photopsia, which presented as different shapes located at the side or above his visual field, for example, patchy, cord-like, zigzag, curtain-like or irregular shapes. The shape was inconsistent during each attack, however, the color was mainly gray or light blue. The visual symptoms gradually disappeared in about 30 minutes. Our patient has never suffered a headache attack during or after the visual aura. Normal results were observed in his neurological and eye examinations, complete blood test, electroencephalogram and neuroimaging examination. TAWH is an uncommon phenomenon of migraine. Migraine with visual aura mainly presents positive and dynamic symptoms. It has a benign course and can be diagnosed after exclusion of other organic diseases such as TIA and epilepsy.

    ABSTRACT: Pseudoachalasia is a rare disease that accounts for only a small percentage of patients with dysphagia. Neuroendocrine tumors are rare malignancies that most commonly originate within the gastrointestinal tract, with the next most common site being the lungs. Esophageal neuroendocrine tumors are the least common site within the gastrointestinal tract. Pseudoachalasia can be secondary to a malignant process within the body. Its typical characteristic in elderly patients is a short duration of symptoms with substantial weight loss. A 68-year-old woman presented with worsening dysphagia that had started six months after the resection of a large cell neuroendocrine carcinoma of the lung in 2011. An extensive work-up in 2012, including esophagogastroduodenoscopy, chest computed tomography and positron emission tomography, was unremarkable. Esophageal manometries revealed findings characteristic of achalasia. A repeat esophagogastroduodenoscopy in January of 2014 revealed a nearly circumferential ulcerated, fungating mass in her distal esophagus. Biopsy results confirming a recurrence of her large cell neuroendocrine carcinoma. We report a case of pseudoachalasia due to metastatic large cell neuroendocrine carcinoma of the lung. Our patient had an exceptionally prolonged duration of symptoms preceding the local esophageal recurrence, which was eventually revealed via endoscopy.

    ABSTRACT: Here we present our clinical experience in a case of esophagus perforation due to the swallowing of a bone piece causing acute angina pectoris and leading to misdiagnosis of acute coronary syndrome. A 73-year-old Caucasian man underwent urgent coronary angiography with possible diagnosis of acute coronary syndrome. His coronary arteries were found to be normal. A computed tomography examination revealed esophagus perforation by a foreign body (a piece of bone), and he underwent urgent left thoracotomy and the foreign body was removed. Sometimes, even a piece of bone within a meal can lead to esophagus perforation, and injure the pericardium and myocardium. The symptoms of esophagus perforation may be confused with acute coronary syndrome due to their similarities and lack of knowledge about the detailed clinical history as shown in our case. Thus, careful consideration of detailed clinical history as well as choosing an appropriate medical imaging modality, such as computed tomography, should always be kept in mind in order to promptly diagnose and start early treatment to reduce mortality.
