Cutaneous T-cell lymphoma associated with the acquired immunodeficiency syndrome.

Four cases of T-cell lymphoma occurring in the setting of the acquired immunodeficiency syndrome (AIDS) have been reported previously. We describe a 46-year-old man with AIDS in whom a cutaneous T-cell lymphoma with lymph node involvement developed. Immunohistochemical staining of the skin revealed the lymphoid infiltrate to be CD3+, CD4+, CD8+, and T-cell antigen receptor alpha/beta positive. Co-infection with human T-cell lymphotropic virus type I was not detected by polymerase chain reaction. Human immunodeficiency virus infection may have contributed to the development of this patient's lymphoma. This case represents the rare occurrence of cutaneous T-cell lymphoma and AIDS.
