# Oral Granular Cell Tumour on the Mandibular Gingiva in an Adult: A Rare Case Report

## TL;DR

This case report describes a rare instance of a granular cell tumor found on the gum instead of the tongue in an adult.

## Contribution

The novelty is the rare presentation of a granular cell tumor on the mandibular gingiva rather than the typical tongue location.

## Key findings

- A 75-year-old man had a granular cell tumor diagnosed on his mandibular gingiva.
- Granular cell tumors are typically found on the tongue, not the gums.
- This case highlights the need to consider this tumor type in unusual oral locations.

## Abstract

Introduction: Granular cell tumours are rare benign tumours. In the oral cavity, these tumours are predominantly found on the tongue. This report describes a rare case of a granular cell tumour arising on the gingiva.

Case Presentation: A 75-year-old man was referred to the department with a mandibular gingival mass. Intraoral examination revealed a relatively firm mass in the lingual gingiva around the left mandibular premolar. Biopsy results led to a diagnosis of granular cell tumour.

Conclusion: Oral granular cell tumours can, in rare cases, occur in areas other than the tongue, such as the gingiva.
