The dentinogenic ghost cell tumour (DGCT) is a rare benign neoplasm, which histologically presents itself as an aberrant keratinisation of the epithelium, ghost cells and dentinoid material. Depending on its location there are two different types of DGCT, central or peripheral, with different clinical characteristics. By 2019, there were only 57 cases of DGCT published: 39 of the central type and 18 of the peripheral type.

In this clinical case, the authors describe the case of a 78-year-old man with a painless and slow growing mandibular lump. The diagnosis of peripheral DGCT was made by incisional biopsy and the treatment consisted of radical excision with upper marginal mandibulectomy.

The aim of the article is to report a clinical case of a rare pathology and, consequently, to help diagnose and better understand its biological behaviour.
