Primary cutaneous mucormycosis in an immunocompetent patient.

Mucormycosis is most common in immunocompromised patients, but it can also occur in healthy hosts, most frequently as primary cutaneous mucormycosis (PCM) and predominantly as a result of skin trauma. We present an uncommon case of PCM in a healthy, young man with no previous history of local trauma. Despite rapid progression of the infection, the patient was successfully treated through surgical intervention and by administering liposomal amphotericin B and posaconazole. He made a full recovery without the need for skin grafting.
