A 77-year-old man had a history of gastric ulcer, for which he used an H2-blocker. In September 2002, early gastric cancer was detected during a periodical endoscopic examination. Distal gastrectomy was performed, and the resected specimen showed a type IIc tumor about 0.8×0.8cm on the posterior wall in the greater curvature side of the antrum. Histological finding disclosed papillary adenocarcinoma and invasion was limited only to the sub mucosa. In the microscopic preparation there was found an eosinophilic granuloma beneath the carcinoma lesion, and a worm body was seen surrounded by necrotic substances. Only 20 cases of compound gastric cancer and Anisakiasis have been reported in Japan, so that any definite relation between both lesions remains obscure. We must be aware of the possibility that the Anisakiasis preferentially infested the cancerous mucosa, and carefully discriminate between cancer and eosinophilic granuloma produced by Anisakiasis.
