Basidiobolomycosis: an unusual fungal infection mimicking inflammatory bowel disease

Basidiobolus ranarum is a fungus belonging to the Entomophthoraceae family and is mainly associated with subcutaneous soft tissue infection. The disease is usually characterized by an insidious onset of massive induration of the subcutaneous tissue involving the limbs, trunk, or buttocks. Most cases of basidiobolomycosis have been reported from Africa, South America, and tropical Asia. Visceral involvement is extremely rare. Only 4 cases with involvement of the gastrointestinal tract, including 1 fatal case originating in the United States, have been well documented in the English-language literature. This case report describes the first successfully treated patient residing in the United States who had B. ranarum infection involving the gastrointestinal tract.
