A 61-year-old man with angioimmunoblastic lymphoma in first complete remission underwent autologous peripheral blood stem cell transplantation. At 1 month post transplant, asymptomatic large granular lymphocytosis developed. The surface marker profile of the cells was CD3+CD8+CD56−CD57+. The disease course was chronic and indolent. The patient remains in complete remission from angioimmunoblastic lymphoma more than 6 months post transplant with persistent large granular lymphocytosis (lymphocyte count, 5-15 × 10/l). Although post transplantation T-cell lymphoproliferative disorders have mostly occurred in allogeneic transplantation recipients and presented as aggressive lymphomas/leukemias, we suggest that chronic indolent T-cell large granular lymphocytic leukemia can occur after autologous stem cell transplantation.
