L95.9: Vasculitis limited to skin, unspecified

Vasculitis limited to skin, or cutaneous vasculitis, is a medical condition where the small blood vessels in the skin become inflamed. This inflammation can cause damage to the blood vessels, disrupting the normal blood flow and resulting in various skin symptoms. Typically, this condition presents with red or purple spots and patches on the skin, often on the legs. However, it can affect any part of the skin. Other symptoms may include itching, pain, and swelling in the affected areas. In some cases, cutaneous vasculitis may be associated with a more severe systemic vasculitis, which affects other organs and systems. The specific cause of this condition is typically unknown, but it may be triggered by an infection, certain medications, or an underlying disease like lupus or rheumatoid arthritis. Vasculitis can progress in severity and chronicity depending on the individual and the underlying cause. It's essential to have any unusual or persistent skin changes evaluated by a healthcare professional.
