A patient presents with dark pigmented macules on the tongue. Which is NOT a diagnostic consideration?
Show answer and explanation
Correct answer: A. Glossitis
- A. Correct. Glossitis is inflammation (a smooth, red/sore tongue), not a cause of discrete dark PIGMENTED macules — so it doesn't belong on the differential for pigmented lesions.
- B. Peutz-Jeghers syndrome causes mucocutaneous melanotic macules — a valid consideration.
- C. Physiologic (racial) pigmentation produces benign melanotic areas — a valid consideration.
- D. Addison disease causes diffuse mucosal hyperpigmentation — a valid consideration.
