A nodular lesion clinically resembling a fibroma on the lateral tongue – which is NOT in its differential diagnosis (the EXCEPTION)?
Show answer and explanation
Correct answer: C. Verruca (verruca vulgaris)
- A. Incorrect – a classic firm dorsal/lateral tongue nodule in the DDx.
- B. Incorrect – a smooth submucosal nerve-sheath nodule that can mimic a fibroma.
- C. Correct (the EXCEPTION) – a verruca is a papillary, rough/exophytic surface lesion, not a smooth submucosal nodule, so it does not belong in the DDx of a fibroma-like nodule.
- D. Incorrect – it IS the lesion being mimicked, so clearly part of the DDx.
