Mycetoma caused by Microsporum canis in a patient with renal transplant: A case report and review of the literature

Abstract

Microsporum canis is a dermatophyte known to cause superficial skin infections. In immunocompromised patients, it can lead to invasive dermatophytosis. We present a case of biopsy-proven left knee mycetoma caused by M canis in a renal transplant patient. Identification of M canis was achieved via sequencing of the internal transcribed spacer regions. Treatment involved surgical debridement, oral posaconazole, and reduction in immunosuppression. In addition, we provide a review of current literature on invasive M canis infections.

Keywords: Microsporum; dermatophyte; immunosuppressed; invasive; mycetoma; transplant.
