The emerging evidence on oral manifestations of the coronavirus disease (COVID-19) has provoked large debates about their etiology, prognosis, and significance; however, these symptoms may have been underreported and discovered by accidental diagnosis due to the inability of the COVID-19 patients to seek oral healthcare and the low fatality of the oral mucocutaneous lesions. Larger case-series following rigorous reporting guidelines are highly required to enhance evidence robustness; therefore, we aim to demonstrate the characteristics of 26 laboratory-confirmed COVID-19 patients with tongue ulcers according to the CARE guidelines.
