Actinic lichen planus (LP) is a rare form of lichen planus, which is a condition that affects the skin and/or mouth. In actinic LP, specifically, affected people develop mildly itchy, coin-shaped patches on sun exposed areas such as the face, the neck and the backs of the hands. It is extremely rare in Caucasians but it is more common in dark-skinned populations. The exact underlying cause of actinic LP is unknown. Treatment is not always necessary as some cases of actinic LP resolve on their own. Mild cases can often be managed with topical steroids, while more intensive therapies may be required for severe cases.
