Primary Angiosarcoma of the Mesentery: A Case Report

Angiosarcoma is a malignant endothelial cell tumor of lymphatic or vascular origin and is most commonly found in the skin and soft tissue. Primary mesenteric angiosarcoma has rarely been reported. Here, we present a case of primary mesenteric angiosarcoma manifesting as a gradually enhancing mass along with necrosis and hemorrhage.

Squamous Cell Carcinoma of the Pancreas: A Case Report

Squamous cell carcinoma (SCC) of the pancreas is an extremely rare subtype of pancreatic cancer. To our best knowledge, magnetic resonance imaging findings, including diffusion weighted images and the non-hypervascular feature on computed tomography, in patients with SCC of the pancreas have not been reported previously. We present the computed tomography and magnetic resonance imaging findings of SCC of the pancreas in a 63-year-old male patient with no specific past history.

Double Primary Cancer of the Gallbladder and Cystic Duct: A Case Report

Primary carcinoma of the gallbladder is an uncommon and aggressive malignancy. Furthermore, double primary cancer of the gallbladder and cystic duct is extremely rare and few such cases have been reported. So, we report here on the case of double primary cancer of the gallbladder and cystic duct, which was pathologically confirmed after an operation, and we discuss the US, CT and ERCP findings.

A Case of Peritoneal Mesothelioma with Direct Invasion to Gastric Mucosa / 대한소화기학회지

Mesothelioma is a rare aggressive tumor arising from the mesothelial cell and regarded as universally fatal disease with average survival around 1 year. The incidence rate is varied from one to forty per million in different countries and increasing by the year. The most common site of tumor origin is the pleura and only 20% to 33% of mesothelioma arise from the peritoneum. There are increasing reports of malignant mesothelioma with forty to fifty fatal cases per year in Korea. Histological studies with immunohistochemical stain is helpful for the diagnosis of peritoneal mesothelioma and imaging modality alone is not sufficient for diagnosis, so it is difficult to confirm diagnosis. A 64-year-old male patient was admitted to the hospital with a palpable mass on abdomen. The 6x6 cm sized huge mass was seen on the body of stomach adjacent to the peritoneum. We report a case of malignant peritoneal mesothelioma without evident exposure to asbestos, of which direct invasion to the gastric mucosa was confirmed by endoscopic biopsy and immunohistochemical stain.

A case of Klebsiella psoas abscess due to diverticulitis and intestinal tuberculosis / 대한내과학회지

A 38-year-old male-to-female transgender patient who had undergone a transsexual operation 20 years earlier presented with right flank pain and chills. Abdominal CT scan and gastrografin colon enema revealed a right psoas abscess and an abnormal communication between the large bowel and this psoas abscess. She underwent a right hemicolectomy and was finally diagnosed as having a Klebsiella psoas abscess due to perforated diverticulitis and intestinal tuberculosis. Additional antibiotics and antituberculous medication were required. A secondary psoas abscess due to diverticulitis is rare, and to our knowledge, no case combined with intestinal tuberculosis has previously been reported. We present the case with a brief review of related reports.
