A 55-years-old female had anemia and had MDL, GIF and a biopsy done at a certain clinic. The biopsy specimen of the polyp revealed f oveolate hyperplasia (Group I). The patient had an endoscopic resection since the polyp was causing anemia. The polyp was diagnosed as a gastric hyperplastic polyp (GHP) on the greater curvature of the antrum (l0mm in diameter) based on the endoscopic examination. The polyp was resected by endoscopic submucosal dissection (ESD). The resected specimen was found to be a differentiated type gastric carcinoma with a gastric mucin phenotype. The cancer cells were columnar f oveolar type cell similar to there found in GHPs. A part of the polyp was composed of a GHP without dysplasia. This case suggests that F-type carcinoma can arise from a histologically diagnosed GHP.
