Characteristic eruption consists of itchy, shiny, flat-topped violaceous papules and plaques favouring the extremities.
White net-like patches or ulceration of mucous membranes, nail deformity, scarring alopecia, and other types of skin lesions may also occur.
Most patients develop the disease between the age of 30 and 60 years.
Hepatitis C infection may increase susceptibility, especially to oral disease.
Treatment may involve corticosteroids, retinoids, calcineurin inhibitors, immunosuppressants, and phototherapy.
