We describe a case report of disseminated cutaneous sporotrichosis as the initial presentation of AIDS in a 24-year-old HIV-positive male patient. He presented multiple ulcerated skin lesions distributed over the face, thorax, legs and arms. Biopsy of one of the cutaneous lesions was suggestive of sporotrichosis and culture isolated Sporothrix schenckii. Itraconazole was started and the lesions progressively resolved after 15 days of medication. The patient was discharged with this medication but he did not return for follow-up. He died three months later in another hospital. Therapy of sporotrichosis in HIV-infected patients remains unclear and the response to therapy is variable. Itraconazole is highly concentrated in the skin and is one of the options for treatment of disseminated sporotrichosis. Key-words: Sporotrichosis. AIDS. Sporothrix schenkii.

Ele apresentava múltiplas lesões cutâneas ulceradas, distribuídas na face, tórax, pernas e braços. A biopsia de uma das lesões cutâneas foi sugestiva de esporotricose e a cultura revelou Sporothrix schenckii. Foi iniciado o tratamento com itraconazol e as lesões progressivamente involuiram depois de 15 dias de medicação. O paciente teve alta com tratamento ambulatorial, mas não retornou para seguimento. Ele morreu três meses depois em outro hospital. O tratamento da esporotricose em pacientes HIV positivos ainda não está estabelecido. Por sua boa penetração cutânea, o itraconazol é uma das melhores opções para formas disseminadas de esporotricose. Palavras-chaves: Esporotricose. SIDA. Spotothrix schenkii. Itraconazol.
