Infective dermatitis is the pediatric manifestation of infection by human lymphotropic virus type 1 by vertical transmission. The clinic is characterized by exudative, crusty eczema of a chronic and recurrent nature. Presented partial response to antibiotic therapy such as trimethoprim/sulfamethoxazole with recurrences after discontinuing treatment. Dermatologists should become familiar with the characteristic clinical and histological findings, as it could be confused with many common dermatological conditions. The presentation of this clinical case represents a challenge that will allow us to have a better understanding of the pathology, give timely and adequate treatment.
