Disseminated histoplasmosis by Histoplasma capsulatum var. duboisii in a paediatric patient from the Chad Republic, Africa.
Histoplasmosis caused by Histoplasma capsulatum var. duboisii is an endemic mycosis of sub-Saharan Africa that usually affects the skin, subcutaneous tissue, lymph nodes and bones. We present a case of a 10-year-old immunocompetent girl with severe cutaneous and subcutaneous abscesses affecting the head and upper body. Microscopic examination showed polar budding yeasts and short mycelium compatible with H. capsulatum var. duboisii. Cultures were not possible but serology showed antibodies against both H. capsulatum var. duboisii and H. capsulatum var. capsulatum antigens. Presumptive diagnosis of histoplasmosis was done but treatment with itraconazole was inefficacious. After 15 days of treatment with Amphotericin B i/v, improvement was evident and, three months later, the patient was discharged with only residual lesions. Seven months later, no relapses were observed.
