[Conidiobolomycosis (rhinofacial entomophthoromycosis) in Gabon. About of one case].

BACKGROUND

Entomophthoromycosis constitutes a nosological group of subcutaneous mycoses including conidiobolomycosis (rhinofacial form) and basidiobomomycosis (subcutaneous form involving the trunk and the limbs). Conidiobolomycosis is characterized by a progressive nasal and facial deformity giving, in the evolved forms, a "hippopotamus snout". The literature review finds a hundred cases, with a tropism for the humid tropical regions. Methods. We report the observation of a 25-year-old patient, living in the equatorial zone, in the south of Gabon in a humid forest area, presenting a swollen aspect of the face mainly involving the eyelids, the nose and the upper lips.

RESULTS

The diagnosis of entomophthoromycosis was compatible with the histopathological and clinical aspects. The evolution was favorable in terms of facial aesthetics under itraconazole 300 mg/day for 2 months and corticosteroid therapy (bolus of methylprednisone 240 mg/day for 3 days relayed per os at a dose of 0.5 mg/kg/day, i.e. 30 mg/day) of prednisone), maintained for 3 months. The average nasal improvement could not be completed by surgery and the patient was lost to follow-up.

CONCLUSION

This second observation of conidiobolomycosis in Gabon in the same province makes Ngounié a privileged ecosystem for this affection.
