Oral Focal Mucinosis of the Tongue: Case Report and Review of the Literature

Abstract

Oral focal mucinosis (OFM) is an oral mucosal lesion characterized by focal mucosal accumulation that rarely occurs on the tongue. This report describes a rare case of OFM on the right side of the tongue in a 71-year-old female patient. The clinical features of OFM have not been well defined, making it difficult to differentiate it from other lesions based solely on clinical manifestations; therefore, histopathological examinations are necessary. Although OFM on the tongue is rare and has a good prognosis with resection, it should be considered as differential for painless mass lesions in the oral cavity.
