Overview
T-cell-prolymphocytic leukemia (also known as T-PLL) is a rare, mature T-cell leukemia with aggressive behavior and predilection for blood, bone marrow, lymph nodes, liver, spleen, and skin. T-cell prolymphocytic leukemia was first described by Catovsky in 1973. There is no classification system for T-cell prolymphocytic leukemia. The inversion of chromosome 14 (14q11) has been associated with the development of T-cell prolymphocytic leukemia.
