COVID-19-associated facial cutaneous mucormycosis superinfection: A potentially life-threatening disease.

A 49-year-old male was involved in an accident and an abdominal computer tomographic examination revealed papillary renal cell carcinoma of the right kidney. During hospitalization, the patient was infected with COVID-19. In the following COVID-19 treatment, a black dot developed on the right side of the head and face. Antifungal therapy and surgical debridement were initiated and gradual improvement was observed.
