Show answer and explanation
Correct answer: A. Recurrent aphthous ulcer (minor)
- A. Correct, per the clinical description. Minor recurrent aphthous ulcers present as round/oval, shallow, painful ulcers with a yellow-white pseudomembrane and erythematous halo on non-keratinized mucosa.
- B. Herpetic ulcers typically present as multiple small grouped vesicles/ulcers, often on keratinized tissue (attached gingiva/hard palate), differing from a solitary minor aphthous ulcer.
- C. A traumatic ulcer would have a clear history of mechanical/thermal injury correlating with the lesion location, not specified here.
- D. SCC would present as a non-healing, indurated lesion with risk factors (tobacco/alcohol), not the typical recurrent aphthous pattern described.
