Abstract

African Histoplasmosis is deep mycosis caused by Histoplasma duboisii and genitourinary involvement is extremely rare. We report a case of African histoplasmosis in a 27-year-old subject with painful penis ulcer. Ulcer edge biopsy had revealed inflammatory granulomas made of epithelioid cells, lymphoplasmocytes, polynuclear eosinophils and giant multinucleated cells, with ovoid yeasts surrounded by a clear halo. PAS and Grocott stains revealed numerous fungal structures with a morphology measuring 7 to 15 nm. The diagnosis Histoplasma capsulatum var. duboisii was placed and the patient put on itraconazole (400 mg/day) for six months with a good course. African histoplasmosis of the subject penis is an extremely rare entity. The diagnosis of certainty often makes use of histology and mycological examination, and makes it possible to eliminate differential diagnoses such as cryptoccocosis, tuberculosis or cancer.
