Fournier's gangrene (FG) is a polymicrobial aerobic and anaerobic bacterial infection with a rare occurrence of primary fungal aetiology. Here we report a case of FG caused by Candida parapsilosis as the primary organism in a 29-year-old man who presented with perineal soft-tissue infection. He had surgical debridement and colostomy for fecal diversion. He was treated with both antifungal and antibacterial drugs. This case highlights the need to consider fungal pathogens as primary aetiologic agents of FG. This further buttresses the need for antimicrobial stewardship with emphasis on targeted therapy to ensure patient safety.
