Oral Lesions: Red and White Variations

A localized area of disease or injury in any organ or tissue of the body.

A well circumscribed, solid, raised lesion up to 1 cm in diameter.

A well circumscribed solid raised lesion more than 1 cm in diameter.

A white appearance of the oral mucosa caused by increased keratin production.

A white appearance of the oral mucosa caused by abnormal thickening of the stratum spinosum.

A white appearance of the oral mucosa caused by fluid accumulation in the epithelium.

A white lesion caused by necrosis of the oral epithelium.

A white lesion caused by microbes producing pseudomembranes.

A horizontal white streak on the buccal mucosa at the level of the occlusal plane, extending from the commissure to posterior teeth. Caused by pressure, friction, or sucking trauma.

Ectopic sebaceous glands found within normal oral mucosa.

A common mucosal alteration seen on the buccal mucosa. It appears as a faint white, diffuse, and filmy appearance with many surface folds, resulting in surface wrinkling. It cannot be scraped off and disappears on stretching.

A white plaque with a rough surface on the buccal mucosa or lips. It appears paler than the surrounding tissue and is caused by habitual biting of the cheeks or lips due to stress.

Oral lesions caused by hot beverages or foods, commonly seen on the lips and commissures.

White lesions with unknown or increased malignant potential. They are associated with potential oral cancer.

A white lesion that appears as a thick, white plaque on the mucous membrane of the mouth. It can be caused by various factors, including smoking, alcohol abuse, and chronic irritation.

A red, velvety patch on the mucous membrane of the mouth. It is considered a precancerous lesion and requires careful monitoring.

A type of burn caused by contact with chemicals like aspirin, hydrogen peroxide, or sodium hypochlorite.

A white, pseudomembrane covered lesion that has an irregular shape and is often painful.

The white material on a chemical burn lesion can slide off with gentle pressure, leaving an ulcer.

Redness that develops around a chemical burn lesion.

A fungal infection of the oral mucosa that resembles a chemical burn, but is often less painful and can have a cottage cheese-like appearance.

A condition that occurs in patients with severe, untreated kidney failure (chronic), characterized by different types of lesions.

A type of uremic stomatitis characterized by red and inflamed lesions.

A type of uremic stomatitis characterized by ulcers in the mouth.

A distinct, well-defined white lesion on the oral mucosa often surrounded by lines (striae) and may resemble oral leukoplakia.

A red, well-defined area on the oral mucosa, often with lines (striae) at the edges. May appear as desquamative gingivitis.

The most severe type of oral lichen planus, characterized by sores (ulcers) surrounded by a red zone and white radiating lines.

A condition that is characterized by prominent white lines with a sharp edge, which resembles oral lichen planus but is distinguished by pronounced hyperkeratinization and abrupt termination of the lines.

A specific white lesion that develops on the hard and soft palate of heavy cigarette, pipe, and cigar smokers. The lesions are restricted to areas exposed to hot smoke during inhalation. It's not considered premalignant and associated closely with tobacco smoking.

A rare form of smoking where the lit end of the cigarette is held in the mouth, leading to more pronounced palatal alterations considered premalignant.

A condition that occurs in patients with severe, untreated kidney failure. It presents with different types of lesions, including red and inflamed lesions, ulcers, and white lesions.

Common mucosal alteration seen on the buccal mucosa. It appears as a faint white, diffuse, and filmy appearance with many surface folds, resulting in surface wrinkling. It cannot be scraped off and disappears on stretching.

A type of uremic stomatitis characterized by red and inflamed lesions in the mouth.

A type of uremic stomatitis characterized by ulcers in the mouth.

A white lesion caused by the measles virus, appearing as small, discrete, white lesions on the buccal mucosa or gingiva. It is common in children and usually less than 1cm in size.

A common oral condition that can be caused by different factors, including smoking, alcohol abuse, and chronic irritation. It appears as a thick, white plaque on the mucous membrane of the mouth.

A white lesion on the buccal mucosa, gingiva, or lateral tongue, often asymptomatic, appearing as a well-defined, non-scrapable white plaque. It may be associated with trauma or irritation.

A rare genetic disease appearing as bilaterally symmetrical white spongy thick plaques on the buccal mucosa, often present at birth and asymptomatic.

An oral condition associated with denture wear, ranging from small, localized, asymptomatic red spots on the posterior palate to large, confluent crimson red areas, and later progressing to pebbly appearances due to palatal mucosa hyperplasia.

A more severe form of Denture Sore Mouth (DSM), characterized by the development of pebbly appearances on the palate due to hyperplasia of palatal mucosa.

A condition affecting reverse smokers (those who inhale smoke from the non-burning end of a cigarette) characterized by a white lesion that often disappears after stopping smoking.

Treatment for a Reverse Smoker's Lesion typically involves stopping smoking, patient education, and periodic observation. If the lesion persists after 3-4 weeks, surgical excision and histological examination may be indicated if dysplasia is present.
