This report concerns an AIDS patient presenting systemic and cutaneous manifestations of histoplasmosis. A histopathological and mycological examination of the skin lesion confirmed the diagnosis. In AIDS patients histoplasmosis arises mainly when the T-CD4+ cell count is less than 50 cells/mm3. In such cases, histoplasmosis can be severe and if left untreated can lead to death, as occurred with this patient.

Histoplasmosis is caused by Histoplasma capsulatum var. Capsulatum. In patients with AIDS it occurs mainly when the T-CD4-positive cell count is less than 50 cells/ mm3. In such cases,this mycosis can be severe and if left untreated can lead to a lethal outcome, as in the patient reported here. 2.3 Clinical symptoms may include fever, hepatosplenomegaly, lymphadenopathy, pulmonary manifestations, skin and mucosal lesions and central nervous system involvement. 3.4 Macular, purpuric, papular lesions (occasionally acneiform or molluscum contagiosum-like), plaques and ulcers can occur together or in isolation (Figures 1 and 2). Erosive lesions or ulcers can occur in the oral mucosa. 4-7 Diagnosis is made by direct examination, culture and histopathology (Figures 3 and 4). The treatment of severe cases (T-CD4+ counts of below 100 cells/ mm3 and/or general state of health compromised) consists of amphotericin B (1mg/kg) until complete regression of clinical symptoms, followed by maintenance with fluconazole or itraconazole (200-300 mg/day) until the T-CD4+ count reach es 150 cells/mm3.1,4-7
