Basidiobolomycosis is a rare deep mycosis, described for the first time in 1956 in Indonesia. Due to Basidiobolus ranarum, a saprophytic soil and plant agent, basidiobolomycosis occurs in black Africa, India, the Far East, Latin America and Southern United-States of America. It affects children and adolescents, with a maximum of between 6 and 10 years. Inoculation is transcutaneous direct through microtrauma, stings of contaminated spines, insect bites. The clinic is made of firm dermo-hypodermic plaques that are very clearly circumscribed, and generally cold and painless; it becomes hot and painful by outbreaks. These cupboards can ulcerate during evolution. Due to its non-specific clinical features, it raises the problem of differential diagnosis with Buruli ulcer especially in co-endemic areas. Basidiobolomycosis can cause invasive pathology by lymphatic or vascular dissemination. Positive diagnosis is based on histopathology with the presence of the Splendore-Hoeppli phenomenon in the dermis. Treatment currently relies on imidazole antifungals: itraconazole or long-term ketoconazole with few side effects. We report a case of disseminated basidiobolomycosis that simulated a multifocal category 3 Buruli ulcer in an immunocompetent 5-year-old girl.
