Cutaneous mucormycosis

Mucormycosis is an aggressive invasive fungal infection that occurs rarely in immunocompetent but frequently in immunocompromised patients. We present a case of a 68-year-old patient with cutaneous mucormycosis due to Rhizopus pusillus. He was initially hospitalized for invasive pulmonary aspergillosis and diabetes mellitus secondary to acute graft-versus-host treatment with glucocorticoids after allogeneic hematopoietic stem cell transplantation for acute myeloid leukemia. Treatment with liposomal amphotericin B and posaconazole was initiated but the patient developed septic shock with multiple organ failure and died 5 days later. The risk factors, clinical presentation, treatment, and prognosis of cutaneous mucormycosis in hematopoietic stem cell and solid organ transplant patients are discussed.
