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

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