RESUMEN

When present for a first time blood donation, a 28-year-old Brazilian white female reported a pruritic eczema of the scalp and retroauricular areas since childhood that had been frequently infected. Her mother had been diagnosed as having HTLV-I-associated myelopathy (HAM), and the patient was found to be a human T-lymphotropic virus type-I (HTLV-I) carrier. The patient had been breast-fed for 6 months. The patient had a complete examination, and a biopsy was taken from eczema in the retroauricular area. The byopsy indicated chronic lymphohistiocytic dermatitis with no abnormal lymphocystes. Eleven months later, the patient had an infliltration in the skin of the retroauricular area and a new biopsy revealed atypical lymphocytes. Nested polymerase chain reaction (PCR) was positive for HTLV-I and immunohistochemistry of the tissue at this time confirmed adult T-cell leukemia/lymphoma (ATLL). Retrospective immunohistochemistry showed that the first fragment submitted from the biopsy 11 months before was also compatible with the diagnosis of ATLL. This case fulfilled all major criteria for diagnosis of HTLV-I-associated infective dermatitis (HTLV-I-ID). We postulate that the patient has indolent ATLL associated with HTLV-I infective dermatitis since childhood. We recommended that tissue immunohistochemistry analysis be done in any patient with HTLV-associated infective dermatitis.
