Overview
Lichen Planus
Lichen planus is an inflammatory condition that can affect the skin, mouth, nails, scalp, or genital areas. It often causes small, itchy, or painful lesions that may appear suddenly or develop gradually. The condition is not contagious and may persist for months or longer. The appearance of lichen planus varies depending on the body area involved. Skin lesions are often purplish, flat-topped, and intensely itchy, while lesions inside the mouth may appear as white lines or patches and can sometimes be painful. Nail, scalp, or genital involvement can require additional assessment. Symptoms may improve over time but can recur.
Basal Cell Carcinoma
Basal cell carcinoma is the most common type of skin cancer and develops from basal cells in the skin. It most often occurs on areas exposed to ultraviolet radiation, particularly the face, scalp, ears, neck, and arms. Lesions may appear as a pearly or shiny bump, a persistent sore, a scaly patch, or an area that repeatedly bleeds or heals and returns. Early evaluation helps guide treatment.

GeneticsDiagnosis
Lichen Planus
Diagnosis is based on the appearance and location of the lesions and the medical history. A healthcare professional may examine the skin, mouth, nails, or other affected areas. A skin biopsy may be performed when the diagnosis is uncertain or another condition needs to be excluded. A clinician may inspect the distribution, color, shape, and surface of lesions and ask about medications and associated symptoms. Oral lesions may require examination of the gums, cheeks, tongue, and other mucosal surfaces. Biopsy findings can support the diagnosis when clinical features are atypical.
Basal Cell Carcinoma
Basal cell carcinoma is usually suspected from the appearance of a persistent or changing skin lesion and confirmed by biopsy. A healthcare professional examines the lesion and surrounding skin and may use dermoscopy for additional visual assessment. A biopsy provides tissue for microscopic examination and establishes the diagnosis. Further imaging is generally reserved for lesions that are unusually large, deeply invasive, recurrent, or suspected of involving important nearby structures.
Prevention
Lichen Planus
There is no guaranteed way to prevent lichen planus because its exact cause is uncertain. Avoiding known triggers or medicines that have previously caused reactions may reduce recurrence in some people. Regular dental care and avoidance of irritating oral products can help when the mouth is affected. Prevention is mainly focused on reducing known aggravating factors because the underlying cause is uncertain. People who develop lichenoid reactions after a medication should discuss alternatives with their healthcare professional rather than stopping prescribed treatment independently. Gentle skin and oral care can reduce irritation in affected areas.
Basal Cell Carcinoma
The most important preventive measure is protection from ultraviolet radiation. Using broad-spectrum sunscreen, wearing protective clothing and hats, seeking shade, and avoiding tanning beds can reduce cumulative UV exposure. Regular awareness of changing or persistent skin lesions can promote early detection. People with previous skin cancer or substantial sun exposure may benefit from regular professional skin examinations and should report suspicious lesions promptly.
Risk Factors
Lichen Planus
Risk factors for lichen planus may include certain medications, hepatitis C infection, immune-system abnormalities, and other triggers. It can occur at any age but is more common in adults. Some people may also develop the condition after exposure to specific substances or treatments. Some people with lichen planus have associated autoimmune or inflammatory conditions. Certain medicines can produce lichenoid reactions, and hepatitis C has been associated with the condition in some populations. Oral disease may be influenced by local irritation, dental materials, tobacco exposure, or other factors, although these associations do not mean that they cause every case.
Basal Cell Carcinoma
Risk increases with cumulative ultraviolet exposure, frequent sunburns, use of tanning beds, fair skin, light-colored eyes, a tendency to burn rather than tan, and a history of significant sun exposure. Previous basal cell or other skin cancers increase future risk. Immunosuppression, previous radiation therapy, and certain inherited disorders can also increase susceptibility. Risk generally rises with age because ultraviolet damage accumulates over time.
