Possible Causes
Generally, Purple rash can be related to:
- Purpura Simplex
This is simple bruising and is very common. It often looks like purple/red dots and patches in the skin.
- IgA Vasculitis (Henoch-Schonlein Purpura)
A disease that causes inflammation and bleeding of small blood vessels, commonly affecting the skin, joints, intestines, and kidneys. This can lead to rashes, stomach pain, and kidney damage. Though it can affect anyone, it is more common in children under 10 years old. The cause is not well understood, but it may result from an immune system issue.
- Hypergammaglobulinemic Purpura
Hypergammaglobulinemic purpura of Waldenström is a very rare condition caused by underlying dysfunction in the immune system. It consists of three main findings: 1. High levels of immunoglobulins in the blood (hypergammaglobulinemia) 2. Rash of tiny red/purple spots due to small blood vessels leaking into the skin (recurring purpura) 3. A blood test that shows high levels of inflammation in the body (Erythrocyte Sedimentation Rate) The cause is unknown but it is often associated with some underlying disease of the immune system. It commonly occurs in middle-aged women and may be triggered heat exposure, tight-fitting clothing, and extended periods of standing.
- Purpura Pigmentosa
Acquired Hemophilia
- Immune Thrombocytopenic Purpura
- Hemangiosarcoma
Congenital Hemophilia
- Cushing's Syndrome
