Candida glabrata oropharyngeal infection in a patient with oral squamous cell carcinoma after COVID-۱۹ infection

Background and Purpose: The COVID-۱۹ pandemic may be an aggravating risk factor for the delay of the diagnoses of serious illnesses, such as oral squamous cell carcinoma, as well as poor management of patients with underlying morbidities, the onset of oral lesions, and antifungal susceptibility to opportunistic fungal infections. Oral candidiasis is one of the most common oral features of COVID-۱۹.Case Report: This study aimed to report an ۸۳-year-old female diagnosed with oral carcinoma who developed oropharyngeal candidiasis after falling ill with COVID-۱۹. In late ۲۰۲۰, this patient was hospitalized for COVID-۱۹ pneumonia. A fissured tongue with white scars appeared after the COVID-۱۹ recovery that caused pain, dysphasia, and dysarthria. The sequencing result based on the internal transcribed spacer rDNA region confirmed Candida glabrata. Its antifungal susceptibility showed susceptibility to nystatin, fluconazole, and caspofungin, but resistance to the other azoles and amphotericin B.Conclusion: Risk of fungal infections, such as Candida seems to be high in patients with severe COVID-۱۹, mainly affecting the oral mucosa. However, whether they are directly attributed to COVID-۱۹ or other surrounding factors is unknown.
