Primary bone marrow lymphomas are infrequent. We report a case of primary bone marrow T-cell lymphoma in a 33-year old patient who has been treated as a hypocellular marrow. There was no enlarged lymph nodes or organomegaly. The peripheral blood smears showed several lymphoid atypical cells. The bone marrow biopsy revealed markedly increased cellularity and disclosed malignant lymphoma, diffuse, large-cell, immunoblastic type The lymphoma cells disclosed positive reaction in leukocyte common antigen (CD45) and UCHL-1 (CD45RO) antibodies which is compatible with a T-cell phenotype. The patient was received allogeneic bone marrow transplantation.
