First culture-proven gastrointestinal entermophthoromycosis in the United States: a case report and review of the literature.

The zygomycosis are fungal infections often occurring in compromised hosts. We report the first culture-proven case of a gastrointestinal infection in the United States by Basidiobolus haptosporus (ranarum). The clinical and histological features are noted in order to distinguish this infection from the more widely reported mucormycosis.
