[Duodenal ulcer with penetration into the liver. Endoscopic-biopsy diagnosis].

BACKGROUND: Penetration into the liver is a rare complication of peptic ulcer. Usually the diagnosis is made by operation or autopsy. We found only 13 reports, in which hepatic penetration was confirmed by endoscopy and histopathological examination of the gastroscopic biopsy. Large ulcers with a pseudotumoral mass protruding from the ulcer bed and the presence of liver tissue in the biopsy specimen were the main findings. CASE REPORT: We describe clinical, endoscopic and microscopic findings in another case.
