Zusammenfassung
Durch Penetration eines Magenulkus in die Leber kann in einer Biopsie aus dem Ulkusgrund die falsche Diagnose eines Magenadenokarzinoms resultieren. Bei bioptischem Nachweis verdächtiger „hepatoider“ epithelialer Zellelemente sollte die Möglichkeit von im Magenulkus miterfasstem regelrechtem Leberparenchym bedacht und z. B. immunhistochemisch abgeklärt werden.
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.
