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.

Oral leukoplakia, pemphigus, lichen planus, hairy tongue and geographic tongue are different typical conditions that appear in the oral mucosa. 00:00.1) Leuk

Abstract. Introduction: Leukoplakia (LKP) is defined as a white patch or plaque on the mucosa of oral cavity, vulva, vagina etc., which cannot be removed and cannot be clinically or microscopically explained by presence of a disease. 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.

though this is not universally accepted to be a distinct clinical entity from idiopathic leukoplakia generally, as it is distinguished from the latter by location only. Usually sublingual keratoses are bilateral and possesses a parallel-corrugated, wrinkled surface texture described as "ebbing tide". Background: Oral leukoplakia can be treated using a variety of treatment procedures; however, the lesions recur in many cases irrespective of the treatment procedure used. The rate of recurrence was from 7.7% to 38.1%.

Oral hairy leukoplakia is a corrugated ("hairy") white lesion on the sides of the tongue caused by opportunistic infection with Epstein-Barr virus on a systemic background of immunodeficiency, almost always human immunodeficiency virus (HIV) infection.
