COVID-19 and fatal renal mucormycosis: Contributory or coincidental?

Association of mucormycosis with COVID-19 disease is emerging as a matter of concern, with multiple reports of rhino-cerebral-orbital and pulmonary involvement. The association of isolated renal mucormycosis in a patient with a history of COVID-19 infection is unknown. The immune dysregulation associated with COVID, along with the use of steroids, mechanical ventilation, and interleukin-6-directed therapies, predisposes to the development of mucormycosis. We report a rare case of primary renal mucormycosis in a young male following recovery from COVID-19. The unusual mode of presentation, rapidly progressive disease course, and the ensuing dilemmas in diagnosis and treatment merit critical analysis.
