A Case of Small Cell Variant of T-Cell Prolymphocytic Leukemia

ABSTRACT

T-cell prolymphocytic leukemia (T-PLL) is a post-thymic T-cell malignancy that has an aggressive clinical course and it is a distinct clinico-biological entity from other T-cell disorders. It is now apparent that this disease represents a separate entity from CLL. Clinically, T-PLL presents with hepatosplenomegaly, lymphadenopathy, skin lesion, and marked lymphocytosis exceeding 100x109/L. Because its clinical course is aggressive, the treatment is difficult. We report a case of small cell variant of T-cell with a review of literatures.
