Neurogenic Sarcoma of the Stomach, a Case Report

　胃粘膜腫瘍のうちでも，胃神経性腫瘍は比較的稀な疾患であり，著者らの調査したかぎりにおいてはレックリングハウゼン病に合併しない孤立性の胃神経肉腫例は本邦においてみあたらない．

　A 49-year-old woman, hitherto in good health, had a sudden bout of hematemesis and melena, so that she was hospitalized. Roentgenogram and endoscopy of the stomach revealed a walnut-sized tumor on the anterior wall of the angle. The tumor had an ulceration in its midst with central necrosis. It also showed bridging folds, but otherwise it was covered with normal mucosa. As bleeding was considered to have arisen from the ulcer, operation was performed. Surgery revealed no abnormal findings in other viscera, nor was there any superficial lymph node swelling or subcutaneous nodules. Gastrectomy was done according to Billroth I method. The resected neoplasm was a very localized one, measuring 2.5×3.0×4.0 cm, spherically protruding with ulceration. Histologically it was diagnosed as neurogenic sarcoma of the stomach. The present case, of a very rare occurrence among submucosal tumors of the stomach, is the first of this kind to be reported in this country.
