title: Primary and isolated adult T-cell leukemia/lymphoma of the bone marrow.
abstract: The distribution of adult T-cell leukemia/lymphoma (ATLL) is typically systemic. In addition to peripheral blood (PB) and lymph nodes, extranodal sites such as the skin, lung, liver, gastrointestinal tract, and central nervous system are frequently involved. We report a unique case of ATLL in which the patient presented with prolonged fever. A 65-year-old man had high-grade fever lasting for 2 weeks. He showed no lymphadenopathy, hepatosplenomegaly, skin lesions, or PB involvement. Bone marrow examination showed widespread infiltration of ATLL cells. (18)F-fluorodeoxy glucose positron emission tomography (FDG-PET) revealed that the disease was confined to the bone marrow.
