Question: What are the symptoms of Lichen planus pigmentosus ?
Answer: What are the signs and symptoms of lichen planus pigmentosus? Lichen planus pigmentosus (LPP), a rare form of lichen planus, is characterized by oval or irregularly shaped brown to gray-brown macules and patches on the skin. Areas that are exposed to sun such as the forehead, temples and neck are most commonly affected. However, the macules and patches may also develop on the trunk or in places where two areas of skin touch or rub together (i.e. the armpit, groin, etc). LPP is a chronic, relapsing condition with periods of exacerbations (worsening symptoms) separated by periods of remission (a decrease in or disappearance of symptoms). Although the skin findings of LPP are usually not associated with any additional symptoms, some affected people may experience mild itching and/or burning or develop other features of lichen planus.
