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 line, a horizontal streak on the buccal mucosa at the level of the occlusal plane extending from the commissure to the posterior teeth.

Ectopic sebaceous glands within normal mucosa, present in 80 to 90% of the population.

A common mucosal alteration seen on the buccal mucosa, appearing as a faint white diffuse and filmy appearance with many surface folds resulting in surface wrinkling, not scrappable, and disappears on stretching.

A white plaque with rough surface on the buccal mucosa or lips, appearing paler than surrounding tissue, caused by stress-related biting.

A condition that occurs in severe, untreated renal failure (chronic) patients, characterized by a red, inflamed, and often ulcerated oral mucosa.

A family of lesions with different etiologies sharing a common clinical and histologic appearance, including disorders like Lichen Planus, Lichenoid Contact Reactions, Lichenoid Drug Eruptions, and Lichenoid Reactions of Graft-versus-Host Disease (GVHD).

A chronic inflammatory disease that can affect the skin, hair, and nails, and can also occur in the mouth, with characteristic white lace-like patterns and red patches.

The form of OLP characterized by fine white lines or striae, often forming a network or annular (circular) patterns, frequently appearing in buccal mucosa, sometimes on the mucosal side of the lips or at the vermilion border.

The form of OLP that typically presents in the initial phase of the disease, characterized by small white dots that often intermingle with the reticular form.

The form of OLP presenting as a homogeneous, well-demarcated white plaque, often surrounded by striae, frequently seen in smokers and possibly transforming into oral squamous cell carcinomas.

The form of OLP characterized by a homogeneous red area, often with striae in the periphery, sometimes affecting only the attached gingiva, and potentially presenting as desquamative gingivitis.

The most disabling form of OLP, characterized by fibrin-coated ulcers surrounded by an erythematous zone with radiating white striae.

A condition that develops at the end of the first week of radiation therapy for head and neck cancers, presenting as redness followed by a pseudomembrane covered with greyish white slough.

A small, discrete white lesion that develops on the hard and soft palate in heavy cigarette, pipe and cigar smokers, restricted to areas exposed to concentrated hot smoke.

A well-defined, white plaque, non-scrapable, often with loss of strechability of the affected mucosa, commonly found in the buccal mucosa, gingiva, and lateral aspect of the tongue.

A rare genetic disease, present at birth, characterized by bilaterally symmetrical white spongy thick plaques on the buccal mucosa, typically asymptomatic.

A condition related to wearing dentures, typically appearing as small, red, localized spots on the posterior palatal mucosa, which can worsen into large red areas and then develop papillary hyperplasia.

A condition that develops in later stages of denture sore mouth, characterized by hyperplasia of the palatal mucosa, producing a red, pebbly appearance.

A condition caused by pressure, frictional irritation or sucking trauma, resulting in a white horizontal line on the buccal mucosa.

Small, yellowish-white or white papules caused by ectopic sebaceous glands in the mucosa, present in a large majority of the population and appearing around puberty.

A condition that appears faint white, diffuse, and filmy with surface wrinkling, not scrappable, and disappears on stretching, caused by an increase in edema in the epithelium.

A condition that appears as a well-defined, white plaque with rough surface on the buccal mucosa or lips, with the affected area appearing paler than surrounding tissue, caused by repeated biting.

A condition that presents in severe, untreated kidney failure (chronic) patients, causing red, inflamed, and often ulcerated oral mucosa.

A group of lesions with different causes but similar clinical and histologic appearance, including Lichen Planus, Lichenoid Contact Reactions, Lichenoid Drug Eruptions, and Lichenoid Reactions of Graft-versus-Host Disease (GVHD).

A chronic inflammatory disease that can affect the skin, hair, and nails, and can also occur in the mouth, often presenting as white lace-like patterns and red patches.
