Nicotinic stomatitis (smoker's palate) — if a patient has a lesion on the TONGUE, which of the following would NOT be in the differential diagnosis?
Show answer and explanation
Correct answer: D. Nicotinic stomatitis (affects the PALATE, not the tongue)
- A. Median rhomboid glossitis is a tongue lesion in the midline dorsum — it IS in the DDx.
- B. Hairy tongue (elongated filiform papillae) occurs on the dorsum of the tongue — it IS a tongue lesion.
- C. Geographic tongue (migratory glossitis) is a common benign tongue condition — it IS in the DDx for tongue lesions.
- D. Correct. NICOTINIC STOMATITIS is caused by chronic exposure to hot pipe/cigar smoke and appears as GREY-WHITE THICKENING with RED DOTS (inflamed duct orifices) on the HARD PALATE — not the tongue. Therefore it is NOT a differential diagnosis for a tongue lesion.
