Sample item

Among oral potentially malignant lesions, which carries the highest risk of already showing dysplasia or carcinoma at biopsy?

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

The answer and the reasoning

D. Erythroplakia

Erythroplakia, a persistent red patch, has the highest malignant potential, and most lesions show severe dysplasia, carcinoma in situ or invasive carcinoma when biopsied. Early biopsy is essential.

Option by option

  • A. Oral lichen planus

    Lichen planus carries a small risk.

  • B. Oral submucous fibrosis

    OSMF carries a lower, though real, risk.

  • C. Homogeneous leukoplakia

    Homogeneous leukoplakia has a lower risk than red lesions.

  • D. Erythroplakia (correct)

    Correct. Red patches are the highest risk lesions.
