A CASE OF GASTRIC LIPOMA WITH EARLY GASTRIC CANCER

Abstract

Gastric lipoma is a rare benign tumor of the stomach. It is commonly detected as a gastric submucosal tumor, however, is hardly made the definite diagnosis preoperatively. We have experienced a case of gastric lipoma with early gastric cancer, in which preoperative CT succeeded in diagnosing. A 57-year-old woman who was diagnosed by a neighbor practitioner as gastric submucous tumor by upper gastrointestinal examinaiton because of her complaint of epigastric and hypochondrial pain, was admitted. Upper gastrointestinal series and endoscopy revealed a submucosal tumor at the pylorus and an early gastic cancer of type IIc+III at the posterior wall of the middle body of stomach. CT indicated that the lesion at the pylorus was arising from adipose tissues. Accordingly, she was diagnosed to have a gastric lipoma with early gastric cancer, and underwent subtotal gastrectomy (B-I) and R2. Pathologically these lesions were a submucosal lipoma and moderately differenciated adenoma limited in mucosa. Gastric lipoma, especially the lipoma accompanied with gastric cancer is so rare that only 16 cases have been reported in Japan.
