Colonic basidiobolomycosis in a child: report of a culture-proven case.

Basidiobolomycosis is a rare fungal disease caused by Basidiobolus ranarum, which is endemic in tropical and subtropical regions of Africa, Asia, and Latin America. Gastrointestinal basidiobolomycosis poses diagnostic difficulties due to the non-specific clinical presentation and absence of predisposing factors. Eight pediatric cases of the disease have been reported recently from Iran, but none of these, or most of the other cases reported in the literature, has been proven by culture, which is the gold standard method for diagnosis. We present a case of culture-proven colonic basidiobolomycosis that occurred in a 3-year-old boy. The outcome was successful following surgical excision and antifungal therapy with posaconazole.

Successful treatment of gastrointestinal basidiobolomycosis with voriconazole without surgical intervention.

Basidiobolomycosis is a rare disease due to fungus Basidiobolus ranarum, an environmental saprophyte that is found worldwide, though mainly reported in the tropical and subtropical regions. Basidiobolomycosis is an unusual fungal skin infection, rarely involves the gastrointestinal (GI) tract. Most of the cases of paediatric GI basidiobolomycosis (GIB) were reported from the southern region of Saudi Arabia. We report an 11-year-old Saudi boy. He presented with a huge right lower quadrant abdominal mass and marked eosinophilia. Abdominal computed tomography scan revealed a large caecal mass. A biopsy was taken and it showed transmural granulomatous inflammation. A diagnosis of GIB was confirmed by specific features in histopathology. Most of the reported paediatric cases with GIB required adjuvant therapy of antifungal and surgical resection. In our case, treatment with voriconazole alone for 1 year was successful with complete recovery and with no recurrence after a year of discontinuing the treatment.

Diagnosis of gastrointestinal basidiobolomycosis: a mini-review.

Basidiobolus ranarum (Entomophthoromycotina) very rarely affects the gastrointestinal (GI) tract. To date, reported paediatric GI basidiobolomycosis cases are 27 worldwide; 19 from Saudi Arabia and 8 from other parts of the world. Often these cases present a diagnostic dilemma, are prone to misdiagnosis and lack of disease confirmation by proper molecular methodologies. The fungal mass removed by surgery is usually sent for conciliar histopathology, isolation by fungal cultures and final molecular testing for basidiobolomycosis. The incidence of basidiobolomycoses, their predisposing factors and the molecular diagnosis of the fungus causing the disease in combination with a phylogenetic framework are reviewed.
