Abstract
The patient was a 82 year-old man with a chief complaint of hematemesis. The emergency endoscopy showed a tumor accompanying with a irregular ulcer and coagula at the gastric fornix. A malignant submucosal tumor was strongly suspected. However, histological finding revealed the inflammatory change in several biopsized tissue. After one month, the lesion disappeared on video-endoscopic examination. Recently, there have been a number of reports concering vanishing tumor of the stomach caused by gastric anisakiasis. In this case, anisakis antibody was detected by immunoelectrophoresis, however neither eosinophlic infiltration nor anisakis bodies were histologically observed. Cases with hematemesis caused by vanishing tumor of the stomach were extremely rare in Japan.
