Double Jeopardy: Cutaneous Mucormycosis in a Renal Transplant Patient Post-COVID-19

Fungal infection as a COVID-19 sequelae in kidney transplant recipients (KTRs) is scarcely reported. COVID-19-associated mucormycosis in KTR presenting as cutaneous involvement is even rarer. This case report highlights this complication in a patient who underwent kidney transplant 17 years prior, was on triple immunosuppression with new-onset diabetes after the transplant, and had chronic graft dysfunction. The patient developed severe COVID-19 pneumonia necessitating parenteral steroids and developed a necrotic ulcer at the intravenous cannula site postrecovery. This was identified as Rhizopus oryzae and treated with de-escalation of immunosuppression, antifungals, and meticulous wound debridement with a favorable outcome. The clinical associations seen in this case are unique and were not found in the literature. This case report strives to encourage clinicians to evaluate for cutaneous mucormycosis in KTRs presenting in a similar clinical setting.
