[Prolymphocytic B-cell leukemia with fatal acute liver failure. A case report].
Prolymphocytic leukemia (LPL) is a well defined entity with a relatively low incidence in our country. This disease usually is seen in patients over 50 years of age, and there is a very definite male preponderance. This lymphoproliferative disorder is characterized by very high white cells counts, massive splenomegaly, poor response to therapy and short term survival. The neoplastic cell in prolymphocytic leukemia usually is of B-cell origin (80% of cases). In our patient, affected by B-lineage prolymphocytic leukemia, a acute hepatic failure occurred, leading him to death in a short time. Autoptic findings evidenced a massive leukemic infiltration of the liver with parenchymal necrosis that caused fatal hepatic failure. Autoptic findings did not show histological patterns of acute viral infections or of any other infectious or systemic disease which could have induced a so massive liver injury. In literature there are no evidences of such a massive and lethal involvement of the liver during prolymphocytic leukemia or chronic lymphocytic leukemia and patients affected by LPL generally come to death because of other causes.
