Abstract
Crusted scabies, formerly known as Norwegian scabies is as uncommon presentation of scabies that may occur in the in association with an immunosuppressive status. The article aims to present a case report in which a male patient with HTLV-1 carrier status admitted for investigation of eczematous and crusted chronic skin lesions and submitted to a dermatologic evaluation and a skin biopsy considering the hypothesis of a cutaneous form of lymphoma associated with HTLV-1 infection had the diagnosis of Crusted scabies instead. There is data regarding de association of crusted scabies and Human T-lymphotropic virus type 1 (HTLV-1) chronic infection. Therefore, this important diagnosis should always be accessed specially in HTLV-1 endemic regions.
