Web10 aug. 2024 · Adult T-cell lymphoma/leukemia (ATL) is a rare lymphoproliferative neoplasm of mature CD4+ CD25+ T cells caused by infection with the retrovirus human T-lymphotropic virus type 1 (HTLV-1). The aggressive subtypes of ATL (ie, acute, lymphoma, and poor-risk chronic) carry some of the poorest prognoses of any of the non-Hodgkin lymphomas.

HTLV-1 is an enveloped, single-stranded RNA virus of the family Retroviridae. The virus displays CD4 T-cell tropism and spread is by direct cell-to-cell contact. Viral RNA is not found in plasma. New infection is therefore usually the result of the transfer of infected lymphocytes rather than cell-free particles.
