Primary cutaneous mucormycosis of the lower extremity in a male patient with diabetes

Mucormycosis is a rare but serious angioinvasive fungal infection that can affect the cutaneous system. Primary cutaneous mucormycosis is caused by direct inoculation and is most prevalent in immunocompromised hosts, particularly those with diabetes. A high index of suspicion is necessary for this condition in patients with rapid and deep extension of necrosis despite aggressive surgical intervention. Deep tissue specimens should be sent for fungal culture and histologic analysis for confirmation of the diagnosis. Early and aggressive debridement to prevent spread to deeper tissues and organs, concurrent antifungal therapy, and medical management of comorbidities are paramount to the treatment of primary cutaneous mucormycosis. This case report highlights the presentation and recommended treatment of primary cutaneous mucormycosis in 1 patient for reduced morbidity and mortality associated with this type of infection.
