Cutaneous and neurologic disease associated with HTLV-I infection.

Abstract

Human T-lymphotropic virus type I (HTLV-I) is the etiologic agent of HTLV-I associated myelopathy (HAM)/tropical spastic paresis (TSP), and adult T-cell leukemia/lymphoma (ATLL). ATLL has been associated with HTLV-I in the southeastern United States. However, to our knowledge, no case reports of HAM/TSP in association with ATLL occurring in the United States have been described. We describe a 40-year-old black woman with a 10-year history of recalcitrant psoriasiform eruption and erythrodermic flares. Medical history is additionally significant for a 2-year history of HTLV-I-associated myelopathy and lower extremity spastic paresis. Polymerase chain reaction with Southern blot analysis was used to detect HTLV-I proviral genome from frozen skin biopsy specimens and peripheral blood mononuclear cells.
