Case Reports

Mucormycosis is rare, and its incidence is difficult to calculate accurately. The causative agents are saprophytic fungi of the class Zygomyces, order Mucorales. Rhinocerebral disease, the most common form, which accounts for more than half of the cases, is associated with diabetes and ketoacidosis. The syndromes of pulmonary and disseminated mucormycosis are usually seen in neutropenic patients. The development of primary cutaneous infection from mucormycosis depends on underlying systemic illness and local host factors. Although mucormycosis is infrequent, more cases of cutaneous infections are being noted, especially in the compromised host. We describe a case of Mucor as a predominant organism in a polymicrobial soft tissue infection in a diabetic patient with necrotizing fasciitis.
