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

## TL;DR

This paper reports a rare case of oral focal mucinosis on the tongue in a 71-year-old woman and discusses its clinical and histopathological features.

## Contribution

The novelty lies in documenting a rare case of OFM on the tongue and emphasizing the importance of histopathology for accurate diagnosis.

## Key findings

- OFM on the tongue is rare and often requires histopathological confirmation for diagnosis.
- The lesion has a good prognosis following surgical resection.
- OFM should be considered in the differential diagnosis of painless oral masses.

## 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.
