Abstract

We present an unusual case of human T-cell leukemia-lymphoma virus type 1 (HTLV-1)-associated adult T-cell leukemia/lymphoma in an human immunodeficiency virus (HIV) patient who presented with non-diffuse, papular, waxing and waning cutaneous eruptions. The patient is a 61-year-old Haitian male with history of HIV on highly active antiretroviral therapy (HAART) who presented with multiple painful pink papules on his distal fingers and back for more than a year with a waxing and waning course. Skin biopsy demonstrated a CD4+, CD25+, CD8- lymphocytic proliferation with a clonal T-cell receptor gene rearrangement. Peripheral blood demonstrated lymphocytosis with a CD4:CD8 ratio greater than 20:1 and an identical T-cell receptor (TCR) clone as that in the biopsy. HTLV-1 antibodies and PCR testing for HTLV virus were positive. Retrospective review of CBCs during the past 8 years demonstrated chronic lymphocytosis with a sharp increase in absolute CD4 counts corresponding to the onset of rash. The patient lacked systemic symptoms after 6 months follow-up.
