Tattoo in the oral cavity

A 60-year-old female patient with an unremarkable medical history presented with a greyish patch on her upper right gums. She also wanted to get her broken tooth fixed. The patient noticed this patch one year ago and its size has not increased since then. On intraoral examination, a flat greyish diffuse pigmentation was present on the right upper buccal alveolar mucosa adjacent to the broken second premolar, measuring about 1 cm x 2 cm (Figure A, black arrow). The pigmentation was nontender with an intact overlying mucosal surface and no ulceration.
