A case of lobomycosis in a patient from the Brazilian Amazon region is presented. Lobomycosis is a subcutaneous mycosis caused by the yeast Lacazia loboi. It often affects adult males and has been reported in dolphins. Therapeutical options for localized lesions, such as the ones shown by the patient in this report, are eletrocoagulation, surgical exeresis, and cryotherapy. Disseminated lesions may be treated with Itraconazole or combination therapy with Clofazimine. There is still no curative therapy for disseminated lesions of lobomycosis.
