Abstract
A rare case of cystic lymphangioma of the stomach is reported. After an annual checkup, a 65-year-old man was admitted to our hospital because of a submucosal tumor of the stomach. On endoscopy, augmentation of the tumor from 2cm to over 3cm in diameter of during six months was observed. Preoperative x-ray examination, endoscopic ultrasonography, and computed tomography all revealed a submucosal cystic tumor at the lesser curvature wall of the antrum. In April 1999, a partial gastrectomy was performed. The resected specimen showed a submucosal cystic mass measuring 5.0×1.2×1.5cm. Pathological diagnosis was cystic lymphangioma in the submucosal layer of the stomach. A literature review identified 69 cases reported to far in Japan. The average age was 53.0 years old, with no detectable difference by sex, and it seems that cystic lymphangiomas are located mostly from body to antrum of the lesser curvature of the stomach and in the submucosal layer of the stomach.
