An autopsy case of Ki-1 lymphoma associated with hepatic failure.

A 62-year-old man was admitted to our hospital because of severe jaundice and fever. Physical examination demonstrated hepatosplenomegaly. The laboratory data revealed elevated serum bilirubin, alkaline phosphatase, lactate dehydrogenase, aspartate aminotransferase and alanine aminotransferase, and the reduced hepaplastin test (Normotest). Computed tomography showed hepatosplenomegaly and swelling of the paraaortic lymph nodes. Although he was treated with antibiotics and steroids, he died of hepatic failure 22 days after admission. At autopsy, his liver weighed 1910 grams, and a histological examination of the liver revealed marked infiltration of CD30 (Ki-1) positive lymphoma cells. He was diagnosed as having non-Hodgkin lymphoma, large cell anaplastic type, Ki-1 lymphoma. We herein report our findings of this very rare case of Ki-1 lymphoma associated with hepatic failure.
