Two cases of foveolar-type gastric neoplasm with raspberry-like appearance

Abstract

We came across two cases of gastric neoplasms. Both the cases showed erythematous lesions in the body of the stomach and were resected en bloc by endoscopic mucosal resection. The pathology was adenoma, MUC5AC-positive, and MUC6-negative, and the diagnosis of foveolar-type gastric neoplasm was made.

Compared to hyperplastic polyps, foveolar-type gastric neoplasms are characterized by a bright color and a narrow white zone on magnified narrow-band imaging. Since the neoplasm may be resolved by biopsy, endoscopic resection is recommended as a treatment when this disease is suspected.
