Associated with HIV+ patients (AIDS may appear within 2 - 3 years) but actually due to EBV infection. Microscopic (histologic) description. Hyperkeratotic oral mucosa due to piling of keratotic squamous epithelium. Oral hairy leukoplakia is caused by Epstein-Barr virus (EBV) infection of the oral mucosa. It most often occurs in association with HIV infection. It has been less frequently described in immunosuppressed patients, especially following organ transplantation, and is rare in immune competent individuals.
Non-homogenous leukoplakia has a greater risk of malignancy than homogenous. Location matters - floor of mouth and ventral tongue lesions higher risk for malignancy. Gross. White lesion - may be subdivided: Non-homogenous. Homogenous. Microscopic.
Nonhomogeneous leukoplakia on tongue/floor of mouth had a 43.10-fold higher risk compared to homogeneous lesions located on buccal mucosa or other sites (P < .05). However, homogeneous leukoplakia in buccal mucosa or other sites of the oral cavity still had the possibility of having carcinoma within the lesion.

Leukoplakia of Tongue Incidence The prevalence of premalignant or malignant transformation is variable but has been estimated The lesions are irregular in outline and separated from adjacent normal mucosa. The surfaces may be nodular. These lesions occasionally coexist with leukoplakia Hairy leukoplakia.

Roch-Berry CS. This paper reviews 117 cases of leukoplakia of the tongue seen at Christie Hospital and Holt Radium Institute between 1932-1972. After confirmation of non-malignancy by biopsy these cases were kept on follow-up for a varying period of time.
