Abstract

A 68-year-old-woman was admitted to our hospital for the follow-up examination of multiple hyperplastic polyps in the gastric remnant. Endoscopic findings showed a pedunculated lesion, approximately 2 cm in size on the greater curvature of the upper body of the stomach. The biopsy specimens revealed group IV and endoscopic mucosal resection was performed. Histological examination showed well differentiated adenocarcinoma at the top of the lesion. Immunohistochemical study (p53, Ki-67) showed that the other areas of the lesion consisted of hyperplastic and dysplastic areas, suggesting that focal cancer in a hyperplastic polyp developed from dysplasia. Focal cancerization in gastric hyperplastic polyp is rare. However, as to hyperplastic polyps in gastric remnant, we should be alert to the change in size and the features of the surface.
