A patient had adult T-cell leukemia-lymphoma in the unusual setting of coinfection with human immunodeficiency virus type 1 (HIV-1) and human T-cell lymphotropic virus type I (HTLV-I). The leukemic cells were CD4 positive and showed clonal genetic rearrangement of the T-cell receptor complex. Cytogenetic analysis showed three clonal karyotypic abnormalities: trisomy 3 and two translocations [t(1;15), (X;1)]. The patient was seropositive for HIV and HTLV-I; HTLV-I and HIV-1 DNA sequences were detected in peripheral blood leukocytes by the polymerase chain reaction. The HTLV-I sequences were detected in a relatively high proportion of mononuclear cells (at least 1 in 30 cells), whereas HIV-1 sequences were detected in a smaller proportion of cells (at least 1 in 3000 cells). Clinical remission was achieved after chemotherapy. There was a decrease in the proportion of HTLV-I positive mononuclear cells (at least 1 in 1000 cells), whereas the proportion of HIV-1 positive cells was relatively unchanged (at least 1 in 1000 cells). Adult T-cell leukemia-lymphoma in the setting of HIV coinfection may become increasingly common because asymptomatic retroviral coinfections are frequent.
