Sample item

Which feature most strongly supports a malignant epithelial neoplasm rather than a benign one?

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

The answer and the reasoning

C. Invasion through the basement membrane

Invasion through the basement membrane demonstrates malignant behavior in epithelial neoplasia and creates access to surrounding tissue, lymphatics, and blood vessels for local destruction and potential metastasis.

Option by option

  • A. Slow growth alone

    Growth rate alone cannot reliably distinguish benign from malignant lesions.

  • B. Uniform cells only

    Uniformity may be seen in benign lesions but is not the decisive criterion.

  • C. Invasion through the basement membrane (correct)

    Correct: basement-membrane invasion is a defining malignant feature.

  • D. Presence of a capsule only

    A capsule often favors benignity but is not an absolute rule.
