Invasive Mixed Fungal Disease after COVID-19: A Series of Seven Cases

Abstract

AbstractCoronavirus disease 2019 (COVID-19) is a recent global pandemic that is caused by the novel severe acute respiratory syndrome coronavirus 2. The patients of COVID-19 are susceptible to a diverse range of secondary infections, fungal being the most common. The increased risk is proposed to be due to the generous use of steroids for the treatment of COVID-19 infection and the presence of comorbidities, such as diabetes mellitus, hypertension, preexisting lung diseases, and/or old age. Invasive mixed fungal disease is potentially life-threatening to the patients of COVID-19. In the present series of seven cases, the authors intend to discuss the clinicopathological profile and gamut of histopathological findings in invasive mixed fungal infection comprising of Mucor and Aspergillus in treated patients of COVID-19. Six patients had a clinical diagnosis of sinonasal–orbital invasive fungal disease, while there was a case of lung infection. The acquaintance and knowledge about histomorphology of invasive fungi and the multidisciplinary diagnostic approach not only will aid in early and accurate diagnosis but can guide the clinician for necessary surgical intervention and initiation of appropriate antifungal medications in patients of COVID-19.
