Cytomorphology of ascitic fluid complicating small cell variant of T-cell prolymphocytic leukemia -Report of a case-

초록

T-cell prolymphocytic leukemia (T-PLL) is a rare mature T-cell lymphoproliferative disorder with post-thymic mature T-cell phenotype. The disease is characterized by rapidly rising lymphocytosis, lymphadenopathy and splenomegaly. The clinical course is usually aggressive along with frequent skin lesion and serous effusions. In 25% of cases the leukemic cells are small in size and the discrete nucleolus of the tumor cells may not be visible in the light microscopic examination.
