Histology of oral hairy leukoplakia
In oral hairy leukoplakia, the mucosa displays mild papillary acanthosis (figure 1). Hyperkeratosis and marked parakeratosis of the superficial epithelial layer is a prominent feature (figure 2). Superficial infections of the hyperkeratinized epithelium with bacteria or Candida may also be seen. The acanthosis is caused by ballooning koilocyte-like cells. (Figures 1, 3). The nuclei of these have a homogenous ground-glass appearance and may contain intranuclear inclusions.
