T-cell prolymphocytic leukemia (T-PLL) is a rare malignancy that comprises about 2% of all mature lymphoid neoplasms. Patients usually present with prominent peripheral blood lymphocytosis, splenomegaly, hepatomegaly, lymphadenopathy, B symptoms, and occasionally with skin lesions.1 The disease follows an aggressive clinical course with rapid progression and typically has a median survival of less than 1 year. In some cases, the disease is indolent for a period of time before becoming aggressive.2 In 2002, 7 years after initial diagnosis in 1995, the case discussed herein was reported as a rare, indolent form of T-PLL.3 We now present 11 additional years of follow-up of this case, during which time the patient remained asymptomatic with respect to his lymphoid neoplasm.
