Sample item

Which oral lesion requires urgent referral because of possible malignancy?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Non-healing ulcer persisting longer than three weeks

A persistent unexplained oral ulcer may represent malignancy and needs prompt specialist assessment, especially with induration, red-white change, or neck nodes.

Option by option

  • A. A traumatic ulcer resolving within several days

    Rapidly resolving trauma ulcers are less concerning.

  • B. Non-healing ulcer persisting longer than three weeks (correct)

    Correct: persistence beyond three weeks is a serious red flag.

  • C. A painless aphthous ulcer healing in one week

    Typical aphthae heal spontaneously within days to weeks.

  • D. Transient bite-line whitening on the cheek

    Linea alba is usually a benign frictional change.
