Erythroplakia of the genital mucosae is often referred to as erythroplasia of Queyrat. The most common areas in the mouth where erythroplakia is found are the floor of the mouth, buccal vestibule, the tongue, and the soft palate. It appears as a red macule or plaque with well-demarcated borders. The texture is characterized as soft and velvety.
Erythroleukoplakia frequently occurs on the buccal mucosa in the commissural area (just inside the cheek at the corners of the mouth) as a mixed lesion of white nodular patches on an erythematous background, [22] although any part of the mouth may be affected. Erythroleukoplakia and erythroplakia have a higher risk of cancerous changes than ...
Leukoedema lesions disappear when the mucosa is stretched, which helps to differentiate it from other white lesions in the mouth. [2] The differential diagnosis is with leukoplakia , oral candidiasis , oral lichen planus , white sponge nevus , morsicatio buccarum , [ 3 ] hereditary benign intraepithelial dyskeratosis and dyskeratosis congenita.
Oropharyngeal cancer, [1] [2] [3] also known as oropharyngeal squamous cell carcinoma and tonsil cancer, [1] is a disease in which abnormal cells with the potential to both grow locally and spread to other parts of the body are found in the oral cavity, in the tissue of the part of the throat that includes the base of the tongue, the tonsils, the soft palate, and the walls of the pharynx.
There may be candidal lesions at other sites in the mouth, which may lead to a diagnosis of chronic multifocal oral candidiasis. Sometimes an approximating erythematous lesion is present on the palate as the tongue touches the palate frequently. [2] [4] The lesion is typically 2–3 cm in its longest dimension.
Hairy leukoplakia is a white patch on the side of the tongue with a corrugated or hairy appearance. It is caused by Epstein-Barr virus (EBV) and occurs usually in persons who are immunocompromised, especially those with human immunodeficiency virus infection/acquired immunodeficiency syndrome (HIV/AIDS).

The mouth is the only place in the body which provides the sensation of taste. Due to these unique physiological features, the oral mucosa must fulfil a number of distinct functions. Protection: One of the main functions of the oral mucosa is to physically protect the underlying tissues from the mechanical forces, microbes and toxins in the ...
