Lichen planus is a skin condition that causes itchy eruptions on the skin. The exact cause of the condition is unknown. Lichen planus most commonly affects people who are middle aged. The condition causes lesions most often on the hands as shown in this photo. Lichen planus papules are shiny and may form confluent plaques. Markings called Wickham's striae may visible on the surface of the lesions. Lichen planus lesions may appear on the front of the lower legs, forearms, and middle of the back. Lesions on the legs may be particularly plaque-like and hypertrophic. People who have lichen planus may have lesions inside or around the mouth.
