Leukoplakia – pathology and pictures
Mucosa of the oral cavity is covered with multilayed squamous epithelium, which is thickened with signs of:
- Hyperkeratosis- excessive accumulation of keratin;
- Parakeratosis- preserved are the nuclei of the cells in stratum corneum and
- Acantosis – hyperpalsia of stratum basale and spinosum of epidermis, with enlarged papillae.
- Subepithelially is found mononuclear inflammatory cell proliferation.
- Often behind the macroscopic diagnostic of leucoplakia (white plaque) is hidden either dysplastic (precancerous) or neoplastic process.
