Fungal Etiology in Diabetic Foot Ulcers: Clinical Mimics, Diagnostic Challenges, and Management Protocols

Dr. Sathaiah Chokkalingam

Abstract: Diabetic foot ulcers are often presumed to be bacterial in origin, yet a growing number of cases reveal underlying fungal infections that resist standard antibiotic treatment. This case report presents a 45-year-old diabetic patient with a Wagner Grade III ulcer, where Candida species were isolated following debridement and confirmed via KOH mount. The patient responded well to antifungal therapy, underscoring the importance of early fungal investigation in non-healing wounds. Recognizing distinct clinical features and timely initiation of antifungal treatment may improve outcomes and reduce surgical interventions.
