Conditions of the mucous membranes

Herpes simplex, often known simply as herpes, is a viral infection caused by the herpes simplex virus. Herpes infections are categorized by the area of the body that is infected. The two major types of herpes are oral herpes and genital herpes, though other forms also exist.

stomatitis characterized by the repeated formation of benign and non-contagious mouth ulcers

rare immune-mediated small-vessel systemic vasculitis in humans

Glossitis can mean soreness of the tongue, or more usually inflammation with depapillation of the dorsal surface of the tongue (loss of the lingual papillae), leaving a smooth and erythematous (reddened) surface, (sometimes specifically termed atrophic glossitis). In a wider sense, glossitis can mean inflammation of the tongue generally. Glossitis is often caused by nutritional deficiencies and may be painless or cause discomfort. Glossitis usually responds well to treatment if the cause is identified and corrected. Tongue soreness caused by glossitis is differentiated from burning mouth syndr

Oral leukoplakia is a potentially malignant disorder affecting the oral mucosa. It is defined as "essentially an oral mucosal white/gray lesion that cannot be considered as any other definable lesion." Oral leukoplakia is a gray patch or plaque that develops in the oral cavity and is strongly associated with smoking. Leukoplakia is a firmly attached white patch on a mucous membrane which is associated with increased risk of cancer. The edges of the lesion are typically abrupt and the lesion changes with time. Advanced forms may develop red patches. There are generally no other symptoms. It usu

chronic disease of skin, tongue or oral mucosa

atrophic glossitis that is characterized as an inflammatory condition of the mucous membrane of the tongue, usually on the dorsal surface

cheilitis characterized by inflammation of one or both of the corners of the mouth

sebaceous glands that are present in most individuals

Human disease

Cheilitis also called and known as chapped lips, is a medical condition characterized by inflammation of the lips. The inflammation may include the perioral skin (the skin around the mouth), the vermilion border, or the labial mucosa. The skin and the vermilion border are more commonly involved, as the mucosa is less affected by inflammatory and allergic reactions.

benign condition characterized by deep grooves (fissures) in the dorsum of the tongue

vascular tumor on both mucosa and skin

rare neurological disorder characterized by recurring facial paralysis, swelling of the face and lips (usually the upper lip - cheilitis granulomatosis) and the development of folds and furrows in the tongue (fissured tongue)

Erythroplakia is a clinical term to describe any erythematous (red) area on a mucous membrane, that cannot be attributed to any other pathology.

medical condition

Epulis (; plural epulides) is any tumor-like enlargement (i.e. lump) situated on the gingival or alveolar mucosa. The word literally means "(growth) on the gingiva", and describes only the location of the mass and has no further implications on the nature of the lesion. There are three types: fibromatous, ossifying and acanthomatous. The related term parulis (commonly called a gumboil) refers to a mass of inflamed granulation tissue at the opening of a draining sinus on the alveolus over (or near to) the root of an infected tooth. Another closely related term is gingival enlargement, which ten

Acatalasia is an autosomal recessive peroxisomal disorder caused by absent or very low levels of the enzyme catalase. Catalase breaks down hydrogen peroxide in cells into water and oxygen. Low levels of catalase can cause hydrogen peroxide to build up, causing damage to cells.

mouth disease characterized by a white patch on the lateral sides of the tongue with a corrugated or hairy appearance; caused by Epstein-Barr virus
