[/INST] Hello and thank you for your question. Based on your question it could be a few things:-Physiological pigmentation-Amalgam tattooing from old fillings-smoking-associated melanosis-oral melanotic macules-melanoma-heavy-metal pigmentation (lead, bismuth, arsenic, mercury)-minocycline pigmentation These are the main ones I can think of.  Google photos of these lesions to see if they look similar.  To be honest, I can't give you a proper diagnosis which out evolution and possible biopsy. Hope this helped.  </s>
