Oral pigmented lesions can be physiological or pathological, exogenous or endogenous, as well as focal, multifocal, or diffuse. Among them, the oral melanotic macule (OMM) is a small, well-delimited brown-to-black macule, often affecting the lip and gingiva. Amalgam tattoo (AT) is a grey or black area of discoloration on the oral mucosa as a result of entry of dental amalgam into the soft tissues, commonly gingiva and alveolar ridge. Herein, we present a patient with gingival pigmentation with features of both OMM and AT in the same location.
