Pigmented purpuric dermatosis is a chronic condition characterized by reddish-brown skin lesions caused by leaky capillaries. Although they can arise on any part of the body, they are most commonly located on the lower legs. In some cases, the skin lesions cause severe itching. The skin lesions may spread over time, or clear up on their own. The cause of pigmented purpuric dermatosis is unknown. While treatment may not be necessary, topical steroids may help control itching. Other options for management include compression stockings, oral medications, and phototherapy.
