Abstract
Basidiobolomycosis is a rare fungal infection that is triggered by the environmental saprophyte Basidiobolus ranarum. Basidiobolomycosis usually presents as an infection beneath the skin and seldom impacts the digestive system. There is no clear clinical presentation, and the majority of initial cases are misdiagnosed. We describe a 68-year-old man who arrived at the emergency room with acute abdomen and shock with air under the diaphragm and needed urgent laparotomy with colonic resection. The patient, however, died from severe sepsis.
