T- cell prolymphocytic leukemia - a rare case.
T- cell Prolymhocytic leukemia (T-PLL) is a rare mature post-thymic T-cell malignancy that is usually reported in the elderly and follows an aggressive course. A 68 year old male presented with a history of weakness and weight loss of two months duration. Clinical examination revealed pallor, enlarged cervical and axillary lymph nodes and splenomegaly. He also had a maculo- papular skin rash. There was marked leucocytosis, anemia and thrombocytopenia (WBC 445 x 103 sub/ml, Hb 8.5 gm/dl, Platelet 25 x 103 sub/microl) with 60% prolymphocytes in the peripheral blood. Bone marrow was hypercellular with an excess of prolymphocytes. Flow cytometric analysis of the bone marrow showed positivity for CD2, CD3, CD4, CD5 and CD 7. T- PLL is a rare T cell disorder with characteristic clinical and laboratory features. Currently, no optimal treatment exists although there has been some success with 2'- deoxycoformycin or Campath-1H.
