A 29-yer-old man was found to have a Borr IV typelike lesion mainly in the body of the stomach by fluoroscopic and endoscopic examinations of the stomach during close examination for bloody stool. Biopsy revealed squamous cell carcinoma. Total gastrectomy with lymph node dissection was carried out. Histopathologically, excepting a portion of the cardiac part, an area from the fundus to body of the stomach was occupied with heterotopic squamous epithelium, among of which squamous cell carcinoma was found. There was no coexistence of adenocarcinoma component. According to “The General Rules for the Gastric Cancer Study”, it has been defined that special type of squamous cell carcinoma arises from the metaplasia of adenocarcinoma to squamous cell carcinoma. However, in this case it is supposed that malignant change of heterotopic squamous epithelium of the stomach might occur.
