[Concurrent appearance of stomach polyposis and hepatocellular carcinoma].

An 18 year old woman had been known to have juvenile polyposis since five years with multiple hyperplastic polyps of the stomach and several polyps of the colon. Death occurred from hepatic coma with hepatocellular carcinoma. A lymphangiosis carcinomatosa was observed in some stomach polyps with a circumscribed infiltration into the stroma and into the adjacent glands. Such an unusual combination of diseases readily causes diagnostic confusion.
