Leukoplakia. (WC/Aitor III)

Leukoplakia is a relatively common clinical finding in clinical medicine. This article looks at leukoplakia of the head and neck.

Hairy leukoplakia is dealt with separately. The typical benign leukoplakia is also dealt with separately.

General

Risk of malignancy:

  • In twos series ~13% were associated with an invasive lesion.[2][3]
  • Non-homogenous leukoplakia has a greater risk of malignancy than homogenous.[3]
  • Location matters - floor of mouth and ventral tongue lesions higher risk for malignancy.[4]

Gross

  • White lesion - may be subdivided:
    • Non-homogenous.
    • Homogenous.

Microscopic

Features:[5]
