Pediatric cutaneous mucormicosis

Dermatol Online J. 2023 Dec 15;29(6). doi: 10.5070/D329662994.


A 9-year-old boy diagnosed with acute myeloblastic leukemia and undergoing chemotherapy, was admitted with febrile neutropenia. During his admission, several violaceous plaques appeared on the upper extremities and anterior left hemithorax, which worsened and acquired a necrotic center. We performed a biopsy and histology showed a cutaneous infarction at the dermoepidermal and subcutaneous level. We observed abundant wide hyphae with right-angled branching and a culture isolated Rhizopus oryzae. A plastic surgery consultant performed a surgical debridement of the lesions and treatment was started with intravenous amphotericin B. The patient did well on treatment and after almost a month of hospitalization, he was discharged with oral posaconazole. Mucormycosis is an opportunistic fungal infection associated with immunosuppression, particularly involving prematurity and hematological diseases in the pediatric age group. Multiple lesions, as in our case, are infrequent. The clinical presentation is variable. Direct smear or histological observation is the quickest diagnostic technique whereas culture is the most definitive. The combination of surgical debridement and amphotericin B is the treatment with the highest survival rates.
