Clinical case with a nodular lesion on the lip/tongue, approximately 2 cm. What type of lesion is described?

Correct answer: A. Irritation fibroma — Nodular lesion

• A. Correct, per the source material. An irritation fibroma classically presents as a firm, smooth, nodular (raised, dome-shaped) lesion resulting from chronic local trauma/irritation.
• B. Petechiae are small, flat, pinpoint red/purple spots from minor hemorrhage, not a 2 cm nodular mass.
• C. A macule is, by definition, a flat lesion (not raised/nodular), inconsistent with this description.
• D. A vesicle is a small fluid-filled blister, inconsistent with a firm nodular 2 cm lesion.
