Cutaneous Leukocytoclastic Vasculitis

The dermatologist is the professional who usually identifies and follows up on cutaneous leukocytoclastic vasculitis, an inflammation of the small blood vessels of the skin that causes damage to their walls and the leakage of red blood cells into the tissues.

How does it present? The most characteristic feature is the appearance of small reddish or purplish spots or welts that don't disappear when pressed, called palpable purpura, especially on the legs. At times they're accompanied by burning or slight pain.

Common causes: It can be associated with prior infections, with certain medications, or with inflammatory diseases of the body, though sometimes no clear trigger is found.

Which specialist treats it? The dermatologist and the pediatric dermatologist assess skin lesions, and in some cases the vascular surgeon or the general practitioner may take part. If you notice these persistent skin lesions, the most prudent thing is to have a professional examine them to guide the workup.
