Post-COVID-19 candidiasis of the tongue in an 18-year old male

Fungal infection in the oral cavity is considered a marker of immunosuppression in certain chronic conditions such as cancer patients on immunosuppression medications and human immunodeficiency virus infections. Currently, coronavirus disease-2019 (COVID-19) pandemic is causing immunocompromised conditions of patients and inviting superadded infections such as local Candida infections such as oral candidiasis and invasive fungal infections. The role of opportunistic fungal infections in the morbidity and mortality of COVID-19 infections remains less established. Overuse of antibiotics for the treatment of COVID-19 infections is also thought to hamper normal flora in the oral cavity which is also an important risk factor for aggravating opportunistic fungal infection in the body. Here, an 18-year-old immunocompetent male presented with a white patch on the dorsal surface of the tongue, which developed 1 week after relieved from COVID-19 infection. The microbiological test of the whitish patch over the tongue confirmed candidiasis.
