A gastric schwannoma presenting as an abdominal mass / 대한내과학회지

Schwannomas or neurilemmomas of the gastrointestinal tract are very rare and constitute less than 1% of all gut neoplasms. We experienced a case of schwannoma in the stomach, which is an extremely rare site. The patient was a 55-year-old woman who complained of an abdominal mass. At endoscopy, a 10-cm ulcerated submucosal mass was seen in the posterior wall of the body of the stomach. Computed tomography showed a heterogenous mass in the stomach without metastasis. The tumor was resected with the stomach. Both histological and immunohistochemical staining with S-100 protein revealed that it was a schwannoma.

Duodenal Variceal Bleeding Treated with a Combination of Endoscopic Ligation and Injection Sclerotherapy: Two Case Reports and a Review of the Korean Clinical Literature / 대한소화기내시경학회지

A duodenal varix is a rare cause of hemorrhage in patients with intrahepatic and extrahepatic portal hypertension. However, bleeding in these patients is serious and often life threatening. Treatments for duodenal variceal bleeding include endoscopic injection sclerotherapy, endoscopic ligation, surgical procedures and interventional radiology. We report two cases of duodenal variceal bleeding in a 53- year-old male patient and a 63-year-old female patient with liver cirrhosis that presented with hematemesis and melena. Emergency upper endoscopy examinations revealed the presence of large nodular varices with ruptured erosion on the top of the second portion of the duodenum. A combination of the use of endoscopic ligation and endoscopic injection sclerotherapy was performed and successful hemostasis and eradication of duodenal varices was possible in all cases. Another 19 cases of duodenal variceal bleeding that have been reported in the Korean clinical literature were reviewed.

A Case of Tuberculosis of the Esophagus and Duodenum Associated with Pulmonary Tuberculosis / 대한소화기내시경학회지

Esophageal and duodenal tuberculosis are rare form of gastrointestinal tuberculosis. The common complications due to esophageal and duodenal tuberculosis are fistulous communications with the adjacent structures, perforation, obstruction, and upper gastrointestinal bleeding. Massive bleeding in esophageal and duodenal tuberculosis is quite rare. We encountered a case of a 55-year-old male who presented with hematemesis and melena. Esophageal and Duodenal tuberculosis with a duodenal fistula was diagnosed by an endoscopic and radiology examination. He improved after treatment with anti-tuberculosis medication over a 9 month period. We report this case of esophageal and duodenal tuberculosis associated with pulmonary tuberculosis with a review of the relevant literature.
