Huge Gastric Schwannoma Characterized by a Gastric Ulcer During Endoscopy / 대한소화기내시경학회지

Gastric schwannomas are very rare mesenchymal tumors that can occur throughout the gastrointestinal tract, but are most commonly found in the stomach. The majority of patients have no symptoms, while others may complain of epigastric pain or upper gastrointestinal ulcer bleeding. Endoscopic examination of a gastric schwannoma commonly reveals a protrusive mass, but, as in this case, many types of ulceration can be observed with central necrosis. We report on a 62-year-old woman with endoscopic findings of 1 cm sized necrotizing ulceration and an 11 cm sized submucosal mass on radiological examinations. The patient underwent a wedge-shaped resection of the stomach and segmental resection of the transverse colon. Both histological and immunohistochemical staining revealed a gastric schwannoma.

Isolated Left Ventricular Noncompaction Cardiomyopathy Accompanied by Severe Mitral Regurgitation

Isolated left ventricular noncompaction cardiomyopathy (IVNC) is a cardiomyopathy thought to be caused by arrest of normal embryogenesis of the endocardium and myocardium. This abnormality is often associated with other congenital cardiac defects. A 21-year-old man presented to the emergency department with worsening exertional dyspnea during the previous 2 months. Two-dimensional and Doppler echocardiography revealed an enlarged left atrium (LA) and a markedly dilated left ventricle (LV) with preserved LV systolic function, severe mitral valve regurgitation, and prolapse due to chordae rupture. The myocardium of the LV and right ventricle (RV) had excessively prominent trabeculations and deep intertrabecular recesses. He is the first patient in Korea who has undergone mitral valve replacement surgery because of severe mitral valve regurgitation and prolapse due to chordae rupture accompanied by IVNC.

Coffee Enema Induced Acute Colitis / 대한소화기학회지

Rectal enema used for diagnostic and therapeutic purposes infrequently causes colitis. In medical practice, enemas are known to incidentally bring about colitis by mechanical, thermal, or direct chemical injuries. Coffee enema is told to ameliorate the constipation in alternative medicine. We hereby report a case of acute colitis resulting from coffee enema, which was presented with severe abdominal pain and hematochezia.

A Case of Pseudolipomatosis in the Gastric Mucosa / 대한소화기내시경학회지

Mucosal pseudolipomatosis is a recently described endoscopic finding consisting of benign transient lesions. This condition, resembling fatty infiltration, is characterized by the presence of small gas voids in the gastrointestinal wall, particularly in the mucosa. The frequency of colonic pseudolipomatosis is higher than the frequency of pseudolipomatosis of the stomach. Both mechanical and chemical theories have been offered to explain the pathogenesis of colonic pseudolipomatosis. The mechanical theory pertains to an air pressure-related complication of the colonoscopy procedure. The chemical theory concerns a drug-related complication of the detergent used during colonoscopies. However, the pathogenesis of gastric pseudolipomatosis is still unclear. Recently, we had a patient who experienced gastric pseudolipomatosis after endoscopoy and biopsy procedures. In the following report we discuss this interesting case of gastric pseudolipomatosis.
