Cutaneous Vasculitis
Key Points
Cutaneous vasculitis affects small- and medium-sized vessels and can be primary or secondary. Manifestations can include palpable purpura, petechiae, urticaria, ulcers, livedo reticularis, and nodules. Exclude other causes of vasculitis. Do routine laboratory tests and biopsy. Treat the cause when possible.
