Necrotizing fasciitis caused by Mucor indicus in a pediatric bone marrow transplant recipient

Necrotizing fasciitis is a life-threatening, rapidly progressing infection of fascia and subcutaneous cellular tissue typically caused by mixed aerobic and anaerobic bacteria. We present a case report of an immunocompromised 4-year-old female with necrotizing fasciitis from a rare fungal organism, Mucor indicus. The patient underwent multiple debridements and was treated for 10 months, first on liposomal amphotericin B (2 months) then posaconazole (8 months). Mucor indicus is a rarely described pathogen with only nine other cases described. Identification of this organism remains a challenge, and the need for further understanding of risk factors and organism susceptibility testing to help guide treatment is crucial.
