We report a 76-year-old woman with Borrmann 3 carcinoma associated with gastric polyposis, who underwent total gastrectomy and splenectomy. Histopathological study of resected specimens revealed squamous cell carcinoma in some sections keratinization was seen; other sections evidenced adenocarcinoma. Due to intra- acinous epithelial stratification and platyform development, the adenosquamous carcinoma was considered to have originated from squamous epithelial metaplasia of the adenocarcinoma cells. Of 90,639 patients who had undergone resection to treat gastrocarcinoma, 236 (0.26%) had adenosquamous carcinoma. However, only 7 cases were associated with polyposis.
