History of Present Illness

This is an otherwise healthy 17-year-old white male who has had two years of treatment with minocycline for acne. He was referred by his general dentist, Dr. Robert Stockton, for evaluation of discolored oral mucosa, especially in the gingiva and palate. His skin, including his face, showed no evidence of pigmentation.
