A Case of Gastric Carcinoma in Villous Adenoma, Coexisting with Borrmann 2 Type Advanced Gastric Carcinoma

Abstract

We experienced a case of gastric villous adenoma containing carcinoma. The patient, a 74-year-old woman, underwent subtotal gastrectomy for Borrmann 2 type advanced gastric carcinoma. Resected specimens showed another tumor measuring 25×30 mm near the Borrmann 2 type carcinoma. The tumor was diagnosed histopathologically as gastric villous adenoma, coexisting with Borrmann 2 type advanced carcinoma. Part of this villous adenoma was well-differentiated adenocarcinoma Gastric Villous adenoma is rare compared with large bowel villous adenoma. On the other hand, all gastric villous adenomas reported to date, including that in our case, contained carcinoma. Though gastric villous adenoma is rare, its treatment should be the same as treatment of cancer.
