A woman, 62 years of age, complaining of epigastric pain and hematemesis underwent gastric fluoroscopy and endoscopic examinations, by which ulcer was observed in the antrum. Approximately one month later, this lesion became a scar followed by an appearance of the gastric polyp atthe same site another one month later. Under the suspicion of malignant changes, gastrectomy was performed but histologically, it turned out to be a hyperplastic polyp with an ulcer scar, UL-II noted at the foot of the polyp. Throughout the course of the long term observation of gastric polyp, there hardly appeared morphological changes. On the other hand, these observations were proved in some reports by autoradiographic studies on mucous membrane. Furthermore, it is reiterated that polyp grows rapidly up to a certain size within extremely short period of time, however it shows no remarkable changes any more after such a rapid growth. The presented case seems to conform with these opinions because polyp appeared at the site of the ulcer scar within about one month. The authors think that our findings will play some suggestive roles in clarifying the causes of gastic poply.
