BackgroundThe emergence of COVID-19 has devastated many parts of the world. From asymptomatic to symptomatic, the virus causes a wide spectrum of presentations. COVID-19 patients may present with oral manifestations. In Afghanistan, where COVID-19 has severely strained the health care system, much of the population lacks proper oral hygiene. This makes the oral cavity a perfect site for SARS-CoV-2 to manifest clinical signs.Case presentationA 62-year-old male was evaluated in the Dentistry Teaching Clinic of Kabul University of Medical Sciences for a painful erosive lesion on dorsal surface of his tongue. He also complained of fever, cough, and taste alteration. He was referred to Afghan Japan Hospital for COVID-19 testing and tested positive. He was followed on for the treatment of SARS-CoV2. After 2 weeks, the patient tested negative and returned to the dentistry clinic for follow-up. Although there were no other signs of COVID-19, the painful erosive lesion on his tongue persisted. Oral evaluation were performed and the patient was advised to practice good hygiene. After 10 days, we observed an asymptomatic geographic tongue without fever and myalgias and the lesion of dorsal surface of tongue improved from severe condition to moderate.ConclusionIn conclusion, patients with suspected or confirmed SARS-CoV-2 should be screened for symptoms and physical findings in the oral mucosa To prevent such an outcome, awareness programs need to be implemented for the diagnosis and management of clinical symptoms among patients.
