Portal hypertension in chronic lymphocytic leukemia is rare. A 66 year-old
man was admitted for splenomegaly, thrombopenia and cholestasis. Endoscopy
showed esophageal varices. The hepatic venous pressure gradient was 15 mmHg
. The liver biopsy showed dense leukemia cells in sinusoidal and portal sit
es. After splenectomy, the hepatic venous pressure gradient normalized but
esophageal varices and cholestasis persisted. The authors discuss the mecha
nisms of portal hypertension in chronic lymphocytic leukemia. Previously re
ported cases are summarized.
