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.[1][2] In some cases, the skin lesions cause severe itching. The skin lesions may spread over time, or clear up on their own.[1] 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.[1][2]

The main features of pigmented purpuric dermatosis (PPD) are petechiae (tiny red spots due to broken blood vessels) or purpura (purple-colored spots or patches due to broken blood vessels), and yellow to brown pigmented patches. The most common sites are the legs, although lesions also may develop in other areas. Infrequently, PPD manifests as a generalized rash. The palms of the hands, soles of the feet, genitalia, and mucosa typically are not affected. Depending on the type of PPD a person has, additional signs and symptoms may include red-brown patches, plaques, linear lesions, itching, and/or other features. In general, PPD does not cause serious health problems but is a chronic condition. Signs and symptoms may persist, wax and wane, or slowly progress, and may go away over a period of months to years.[3]

This table lists symptoms that people with this disease may have. For most diseases, symptoms will vary from person to person. People with the same disease may not have all the symptoms listed. This information comes from a database called the Human Phenotype Ontology (HPO) . The HPO collects information on symptoms that have been described in medical resources. The HPO is updated regularly. Use the HPO ID to access more in-depth information about a symptom.

The cause of pigmented purpuric dermatosis is unknown.[1][2] Occasionally, it occurs as a reaction to a medication, food additive, viral infection or following exercise.[2] In rare cases, there appears to be a genetic component.[1]

If the condition is mild, treatment may not be necessary. For those who suffer from itching, topical steroids and antihistamines may be useful. Compression stockings may be used if the lower legs are affected.[1][2] Additional treatments that have been successful in limited studies include pentoxifylline,[4] aminaphtone,[5] photochemotherapy (PUVA)[6], griseofulvin, oral cyclosporin, and ascorbic acid with rutoside.[7]

If you need medical advice, you can look for doctors or other healthcare professionals who have experience with this disease. You may find these specialists through advocacy organizations, clinical trials, or articles published in medical journals. You may also want to contact a university or tertiary medical center in your area, because these centers tend to see more complex cases and have the latest technology and treatments.

If you can’t find a specialist in your local area, try contacting national or international specialists. They may be able to refer you to someone they know through conferences or research efforts. Some specialists may be willing to consult with you or your local doctors over the phone or by email if you can't travel to them for care.

You can find more tips in our guide, How to Find a Disease Specialist. We also encourage you to explore the rest of this page to find resources that can help you find specialists.
