Periorbital Cellulitis Secondary to Conidiobolus incongruus

A previously healthy, 18‐month‐old girl developed edema and erythema around her left eye 1 week after getting sand in that eye. The patient did not respond to oral or intravenous antibiotics. A mass developed around the eye, and biopsy revealed Conidiobolus incongruus. The patient failed to respond to amphotericin B 1 mg/kg, and susceptibility tests indicated multiantifungal resistance. A combination of antifungal therapy, hyperbaric oxygen, and surgery was required for successful treatment. Three months after treatment the child was disease free. There is no definitive therapy for Conidiobolus incongruus infections, although various drugs have been administered with some success. When susceptibility tests determine multidrug resistance, radical resection with antifungal chemotherapy and hyperbaric oxygen may be necessary as well as lifesaving.
