A rare case of cutaneous mucormycosis in the forearm: A case report.

Introduction And Importance: Cutaneous Mucormycosis (CM) is a less frequent type of fungal infection that can present with different skin lesions. Although these lesions appear to be benign and silent, CM rapidly progresses into the deeper layers. Given that no specific laboratory or imaging finding is described for the disease, the diagnosis is mainly based on history and physical examination. In addition, immediate debridement and antifungal agents must be commenced.

Case Presentation: We present a 43-year-old septic man who was hospitalized for his forefoot infection. During his admission, he developed a necrotic-like ulcer in his antecubital fossa. After initial debridement, pathology examination revealed the infection with mucormycosis. We administered intravenous liposomal Amphotericin B, and also multiple surgeries were performed. Unfortunately, the sepsis progressed to multiorgan failure, and the patient passed away.

Conclusion: CM requires emergent diagnosis and treatment. Early surgical interventions like extensive debridement and repetitive wound irrigation alongside systemic antifungal therapy are the key steps to preventing the progression of the disease.
