Chromomycosis

An HIV-seropositive patient (aged 43 years, normal level of CD4+ peripheral blood lymphocytes) is described with an asymptomatic light-red smooth nodular lesion on the scrotum, since 4 months. Histological and mycological examination showed chromomycosis due to infection with Fonsecaea pedrosoi. Source: possibly Venezuela. Chromomycosis (dermal and/or subcutaneous) is caused by a large group of dark pigment producing moulds belonging to the order of Chaetothyriales, occurring in soil, (rotting) wood and on plants in (sub)tropical areas. Rural work is the most important risk-factor. Treatment options are topical (excision, heat treatment, cryosurgery) or systemic treatment (itraconazol or terbinafin) of long duration or a combination thereof
