An otherwise healthy 17-year-old male who has had two years of treatment with minocycline for acne was presented for evaluation of discolored oral mucosa, especially in the gingiva and palate. His skin, including his face, showed no evidence of pigmentation. His past medical history is non-contributory. The patient is in excellent health and is on no other medications. There is no history of tobacco use.
The patient did not complain of any pain and there was no evidence of swelling, infection, or acute changes. The teeth were slightly tan, but did not show evidence of the bluish discoloration. What can be the diagnosis for the discoloration? Does it need urgent management? *This case is from Docplexus Editorial Team for educative purpose only.
