Lichen Ruber Planus


a chronic disease characterized by the appearance on the skin (mainly of the inner surface of the forearms, wrists, and ankles) of small, shiny, pinkish red, polygonal, pruritic, center-pitted papules. The eruptions may spread over the entire skin surface (with the exception of the face), at the same time affecting the oral mucosa.

The causes of lichen planus have not been established conclusively. There are several theories: nervous, infectious (viral), and toxic, for example. Depending on the character of the clinical manifestations, the condition is classified as annular, vesicular (pemphigoid), verrucose, atrophic, sclerotic, or acuminate. The disease is not infectious. It runs a prolonged course, from several months to several years. The prognosis is favorable; relapses are observed relatively rarely. Treatment involves the use internally of antibiotics, B vitamins, and tranquilizers and externally of antipruritic and anti-inflammatory agents.
