ORAL HAIRY LEUKOPLAKIA
- Hairy leukoplakia is a white patch on the side of the tounge with a corrugated or hairy appearance. It is seen in severe defects of immunity, particularly in HIV infection.
- The cause of this condition is an opportunistic infection by Epstein Barr virus.
- Epstein–Barr virus (EBV) infections in the oral cavity may present as a primary infection (infectious mononucleosis).
- Hairy leukoplakia is an unusual presentation of recrudescent EBV in the oral cavity, where this normally lymphotropic virus is present within the epithelium.
- In patients with established HIV/AIDS, hairy leukoplakia is usually associated with a low CD4 count and high viral load.
