Abstract
Systemic basidiobolomycosis is a rare fungal infection caused by Basidiobolus rararum (B. rararum). The clinical presentation is non-specific and is similar to many gastrointestinal conditions such as Crohn's disease (CD). The most consistent findings of basidiobolomycosis are recurrent abdominal pain, weight loss, fever and peripheral eosinophilia. Most of the patients are diagnosed on surgical resection of the involved region along with compatible histopathological findings like transmural inflammation, granulomas with eosinophilic infiltration (Splendore-Hoeppli phenomenon) and more specifically detection of fungal hyphae on fungal stains. Effective and curative treatment for systemic basidiobolomycosis is available, if diagnosed and managed properly in time. We report here a Saudi boy who had ileo-caecal basidiobolomycosis, but diagnosed after a prolonged course of illness.
