title: [Gastric ulcer suspected of being a carcinoma].
abstract: Following hepatic penetration by a gastric ulcer a pitfall diagnosis of gastric adenocarcinoma can result from a biopsy of the ulcer base. In cases of suspicious "hepatoid" epithelial cells in a gastric biopsy, the possibility of regular liver tissue from a gastric ulcer penetrating the liver should be kept in mind and verified, e.g. by immunohistochemistry.
