Abstract
Gastric lipoma is a rare benign tumor of the stomach. We experienced a case of gastric lipoma with gastric cancer and volvulus. A 78-year-old man, who was diagnosed by a neighborhood practitioner as having a gastric submucosal tumor by an upper gastrointestinal series and endoscopy because of his nausea and general fatigue, was admitted. Detailed examination revealed a submucosal tumor on the greater curvature side of the middle body of the stomach, and an advanced gastric cancer (Borrman 3 type) near the posterior wall of the lower body of the stomach on the greater curvature side. Furthermor, they were accompanied by gastric volvulus. CT showed that the lesion at the middle body of the stomach arose from adipose tissues. Subtotal gastrectomy (Billroth II method), and R2 lymphadenectomy were performed. The pathohistological diagnosis was a lipoma in the subserosa and a poorly differentiated adenocarcinoma with subserosal invasion. Gastric lipoma accompanied by gastric cancer is rare; we found only 18 cases in the Japanese literature. Further, we found no report concerning a gastric lipoma with gastric cancer and volvulus.
