Abstract
Basidiobolus ranarum
is an environmental saprophyte found worldwide. It is a member of the order
Entomophthorales
of the class zygomycete. The infection is generally restricted to subcutaneous tissues. However, the disease can involve visceral organs, causing gastrointestinal basidiobolomycosis (GIB). GIB usually has nonspecific clinical manifestations and its diagnosis is challenging. Missed and delayed diagnosis of GIB increases the risk of morbidity and mortality, especially in pediatric patient. Previously, most of the cases in Saudi Arabia have been reported from southern region (Tohama, Aseer Region); the current study reports cases from different regions. We report a case of severe GIB and four other cases of pediatric GIB in western region of Saudi Arabia. The aim of our report is to describe the wide range of clinical presentations, diagnosis, management and outcomes. Our case series includes the youngest case report of GIB, a 16-month-old infant and highlights two important points. First, the need of high index of suspicious for diagnosis of GIB and its inclusion in the differential diagnosis of any abdominal mass, fever and eosinophilia. Second, it gives additional supportive evidence that medical management with voriconazole without surgical intervention (intervention if the condition is diagnosed early) is curative.
