Abstract
- Hairy cell leukemia (HCL) is a chronic B- cell disorder characterized by the presence of typical hairy cells in the peripheral blood and marrow, pancytopenia, and a variable degree of splenomegaly. Identification of typical hairy cells in the peripheral blood and demonstration of tartrate-resistant acid phosphatase (TRAP) are critical findings in HCL. Hepatic involvement of HCL is a common feature and liver biopsy show diffuse mono-nuclear cell infiltration throughout the hepatic sinusoids and in the portal areas. We report a case of hairy cell leukemia in a 52-year-old man who presented with pneumonia and hepatic infiltration with review of the literatures.
