Oral hair leukoplakia K13.3

Greenspan et al., 1984h

Clinically characteristic whitish changes of the tongue mucosa described in the context of HIV infection. However, the clinical picture can also be observed in non-HIV patients.

• In about 18% of HIV-infected and 36% of AIDS patients.
• Also in kidney or bone marrow transplant patients under immunosuppression
• More common in patients who use steroid inhalers for long periods of time due to pulmonary problems
• Patients with autoimmune diseases that are under long-term immunosuppressive therapy (coincidence with candia infections)

Infection with EBV viruses.

Tongue

Several millimetres thick, white, mostly asymptomatic, non-wipeable mat-like deposits on the lateral edge of the tongue and the lower surface of the tongue.

Hyperparakeratosis with hair-like projections on the surface. Large, ballooned cells with pynotic nuclei. Lack of dermal inflammatory response. Electron microscopic and immunohistochemical evidence of Epstein-Barr virus in the lesions.

Oral leukoplakia; lichen planus; candidiasis; exfoliatio areata linguae; pseudo-hair leukoplakia.

If necessary, brush off and vitamin C (e.g. Cebion) Tbl. 400-1000 mg/day, let Tbl. melt on the tongue. In cases of severe suffering, therapy with acyclovir (e.g. Zovirax) 5 times/day 400 mg p.o. is possible. This includes rapid regression of the hair leukoplakia, but after discontinuation, it often leads to rapid recurrence. Alternatively, Valaciclovir (Valtrex) 3 times/day 1 g p.o. (off-label use; according to studies well effective, lower risk of relapse than under Aciclovir).

Depends on the underlying disease; 80% of patients develop full-blown AIDS within 1-2 years after the onset of oral hair leukoplakia
