Sample item

Which oral lesion should prompt urgent assessment because it may represent oral malignancy?

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

The answer and the reasoning

B. A nonhealing ulcer lasting more than several weeks

A persistent nonhealing oral ulcer, especially with induration, unexplained bleeding, neck nodes, or risk factors, requires prompt assessment because early oral cancer may initially resemble a benign lesion.

Option by option

  • A. A transient food stain on the tongue

    Food staining is temporary and not a tissue lesion.

  • B. A nonhealing ulcer lasting more than several weeks (correct)

    Correct: persistent nonhealing ulceration is an oral cancer red flag.

  • C. A small aphthous ulcer resolving in a few days

    Brief self-limited aphthae are common and usually benign.

  • D. A painless removable denture mark that resolves overnight

    A resolving denture pressure mark is less concerning but should be reviewed if persistent.
