A 73-year-old male ex-smoker of 20 cigarettes/day, with a history of pancreatitis and tuberculosis over 30 years before, presented with a lower gingival lesion that had been present for the past 6 months.
The lesion was painful and produced paresthesias in the territory of the right mental nerve.

Exploration revealed a non-indurated, 2.5-cm ulceration on the edentulous right lower alveolar margin (Fig. 1, Fig. 2, Fig.3). No adenopathies were noted. A biopsy was obtained (Fig. 4, Fig.5, Fig.6, Fig.7).
