RESUMO
Histoplasmosis duboisii (Histoplasma capsulatum var duboisii) is uncommon disease especially in children. It is observed in Africa where the incidence is unknown. The authors report a series of three pediatric cases. The report concerned 2 girls and one boy who were 3, 9 and 4 year-old, respectively. Symptoms evolved for more than two months in each case. At admission, we found fever and poor general condition. Observed lesions were lymphnodes localisation disseminated (cases 1 and 2), subcutaneous (cold abscess) and cutaneous simulating molluscum contagiosum (case 2), osteoarticular (cases 2 and 3), abdominal including peritoneal and hepatosplenic (case 1). In all cases, a mild leukocytosis was found and an accelerated erythrocyte sedimentation rate (ESR) greater than 70mm. The HIV serology was negative. The treatment consisted of itraconazole in 2 cases and ketoconazole in one case. The evolution was insidious, leading to the discharge against medical advice. The death occurred at home in all cases. CONCLUSION: Histoplasmosis duboisii can realize two main clinical presentations (localized or disseminated), affecting the skin, lymph nodes, bones, sometimes the intra-abdominal organs. HIV serology is not always positive in disseminated forms. The evolution is unpredictable and capricious under antifungal treatment. The disease should be well explained to prevent a possible discharge against medical advice, often pejorative.
