title: The value of tartrate resistant acid phosphatase (TRAP) immunoreactivity in diagnosis of hairy cell leukemia.
abstract: Hairy cell leukemia (HCL) is a rare chronic B-cell lymphoproliferative disorder characterized by splenomegaly, pancytopenia, and circulating atypical lymphocytes with circumferential cytoplasmic projections. We investigated the specificity and the sensitivity of anti-TRAP antibody immunoreactivity in 57 cases of HCL. We found that there is a statistically highly significant difference between TRAP immunoreactivities of the study and the control groups, and HCL can be diagnosed by TRAP immunoreactivity in bone marrow trephine biopsy materials with a specificity of 98.27 % and a sensitivity of 100%.
