Аннотация
INTRODUCTION: Histoplasma capsulatum var capsulatum is a dimorphic fungi predominating on the American continent. It is responsible for disseminated histoplasmosis associated with AIDS. The presentation in the form of cutaneous ulceration is uncommon and misleading.
OBSERVATION: A 25 year-old man presented with 3 ulcerations, of 2 to 4 cm in diameter, localized on the lower lip and knees. The patient exhibited fever, alteration in his general status of health and a pulmonary interstitial syndrome. He was seropositive for the human immunodeficiency syndrome (HIV). His lymphocyte CD4+ level was of 1/mm3. Diagnosis of histoplasmosis was established by direct examination and culture of the cutaneous ulcerations and bronchoalveolar washing fluid.
DISCUSSION: The clinical aspect of cutaneous localizations of disseminated histoplasmosis is usually multiple, disseminated, papular or nodular-type lesions. Ulcerations represent less than 20% of the cases described. In our patient, the aspect of the lesions at first evoked cutaneous leishmaniosis. Direct mycological examination followed by culture confirmed the final diagnosis.
