Leukoplakia appears as a whitish, well-defined mucosal patch or plaque caused by epidermal thickening or hyperkeratosis and cannot be scraped off (Figure 1, Figure 2, Figure 3, Figure 4). The term of leukoplakia is not applied to other white lesions such as those caused by candidiasis, lichen planus or other disorders. Figure 1.

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. Histology of oral hairy leukoplakia Non-homogenous leukoplakia has a greater risk of malignancy than homogenous. Location matters - floor of mouth and ventral tongue lesions higher risk for malignancy.

Leukoplakia lesions look like similar patches but are white as opposed to red Oral hairy leukoplakia is a condition that the Epstein-Barr virus (EBV) can trigger. The condition causes white lesions, or patches, on your tongue.

Often on tongue. Caused by EBV. May be seen in the context of a HIV-infection. Gross.

2021-01-28 · The prevalence of the ventrolateral tongue leukoplakia was higher than that of the dorsal tongue leukoplakia (P < 0.001). The results of multivariate logistic regression analysis showed that the degree of pathology was the only independent prognostic factor related to postoperative malignant transformation (P = 0.045).

According to the World Health Organization, the term leukoplakia should be reserved for "white plaques of questionable risk, having excluded other known diseases or disorders that carry no increased risk for cancer" [].A separate disorder that is not premalignant 2013-06-14 2019-08-05 10 specimens taken from oral hairy leukoplakia were compared to 8 histological preparations from hairy tongue. We found 9 criteria helpful concerning the histopathologic differential diagnosis of these entities. Oral hairy leukoplakia shows a gently papillated surface, a prominent horny layer with c … 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.

Features: Often associated with epithelial thickening (hyperkeratosis, acanthosis). DDx: Food debris. 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.

Conclusion: Leukoplakia of the lateral tongue is highly coexistent with malignancy, and incisional biopsy frequently leads to underdiagnosis. Therefore, complete excision with adequate margin is warranted for leukoplakia of the lateral tongue, preferably under general anesthesia, which could be performed with minimal morbidity and function preservation. Typically located predominantly over the dorsum of the tongue, in contrast to the lateral and ventral surfaces, where the vast majority of oral leukoplakia are found; plaques of keratinised tissue with fissured topography are characteristic.
