Geographic Tongue Hairy Tongue (Black Hairy Tongue) Oral Submucous Fibrosis Any condition that increases the thickness of the epithelium causes it to appear white by increasing the distance to the vascular bed. Lesions most often appear white because of a thickening of the keratin layer, or hyperkeratosis. Other common causes of a white appearance include acanthosis (a thickening of the spinous cell layer), an increase in the amount of edema fluid in the epithelium (ie, leukoedema), and reduced vascularity in the underlying lamina propria. Surface ulcerations covered by a fibrin cap can also appear white, as would collapsed bullae. (These latter two types of lesions are covered in Chapter 4, “Ulcerative, Vesicular, and Bullous Lesions.”)
