Conidiobolomycosis, a rare fungal tumor: a case report in Ouagadougou, Burkina Faso

Conidiobolomycosis is a deep, rare mycosis, due to Conidiobolus coronatus which is a saprophyte of vegetation in decomposition. We report one case in Burkina Faso. A 17 years old man, shepherd, consulted for tumefactions on the face. It could date back insidiously to a traumatism, one year before. A month later some painless tumefactions appeared on the cheekbone, the right eyelid, the nose with epistaxis. The upper lip then the lower one had swollen. Dermatological exam revealed multiple, painless, hard, sub-cutaneous swellings, affecting the cheekbone, the eyelids, the root and the ala of the nose. This tumefaction sometimes adhered to underlying tissues and to the overlying skin, sometimes mobile; painless and hard swelling of the two lips was also noted. ENT exam showed an inflammation of the nasal mucous without ulceration and the permeability of the nasal tracts was subnormal. The cephalic tomodensitometry showed a thickness of the soft tissues of the lips and the nose with an infectious feature associated to a pansinusitis without bone lesion. Histology was in favour of conidiobolomycosis. The patient was treated with fluconazole and the swelling progressively disappeared. Conidiobolomycosis is a disease generally reported in some humid tropical countries. It begins in the nasal cavities leading then to a nasal obstruction. This case was singular by the fact it happened in a dry Sudano-Sahelian climate and by its clinical features.
