A 67-year-old African American man was referred for evaluation of an incidental finding of pigmented maculae on his oral mucosa. The patient had not previously been aware of this pigmentation and could not assess its duration. The patient's medical history was notable for heavy alcohol and tobacco consumption, osteoarthritis, hypertension, and esophageal reflux. He denied any history of melena, anemia, or gastrointestinal bleeding. His medications included cimetidine and naproxen. He denied any family history of pigmentary abnormalities or polyposis.
