The figure illustrates a patch of leukoplakia on the lateral margin of the tongue. This patient has been a smoker since his teens, smokes roll ups and recorded 40 pack years of smoking. A homogeneous white patch was found on the lateral margin of his tongue and having excluded other likely conditions this was diagnosed as oral leukoplakia. A biopsy confirmed moderate dysplasia.
Notes: The clinical features are clearly consistent with oral leukoplakia, which is the most common potentially malignant disorder. Smokers carry a higher risk to develop oral leukoplakia. This white patch was excised by laser surgery and the patient is being followed on a regular basis.
