Intraoral findings at the first visit. The upper and lower jaws were edentulous, with a relatively irregular border from the centre of the mandible to the gingiva of the molar region on the left side. Diffuse swelling was observed, accompanied by surface ulceration.

The transverse section was mostly cystoid, but solid portions were also observed (Figure 4).
Histopathological findings. Alveolar cell hyperplasia with a funicular structure in the fibrosing interstitial tissue was observed, as well as a palisade arrangement (Haematoxylin and eosin staining, x150).
