(英) Gastric hamartomatous inverted polyp (g-HIP) is rare gastric elevated lesion forming endophytic growth pattern which etiology remains unknown. G-HIP is said to be associated with gastric cancer and gastritis. We systematically reviewed Japanese g-HIP's clinicopathological features reported before2002. Japanese g-HIP amount to20lesions,18patients ; 7(38 9%)were males and 11(61 1%)were females. The mean age of patients was 60 2 years old. The mean size of the lesions was21 7millimeter. No of the polyp shape was Yamada type IV7, Yamada type I/flat elevation 6, Yamada type III 4 and Yamada II 3, respectively. The site of the lesions was Body11, Cardia3, Fornix3and Antrum1, respectively. In12described cases, accompanied lesion was Gastritis, Carcinoma, GCP, Hyperplastic polyp, GIST and remnant stomach due to ulcer. Of the submucosal shaped(Yamada type I/flat elevation)g-HIP,50% has GCP and62 5% has gastric cancer. The common feature of g-HIP was pyloric gland-like mucous gland proliferation and cystic dilatation in the H. pylori era of Japan.
