Cutaneous Vasculitis
Overview
Cutaneous vasculitis is a kind of vasculitis that affects the skin and subcutaneous tissue but not the internal organs.
Any type of primary or secondary vasculitis, including serum sickness, infections (e.g., hepatitis C), malignancies, rheumatologic or other autoimmune disorders such hypersensitivity, can impact the skin.
Vasculitis can be localized or be part of a systemic primary or secondary vasculitic disorder. Livedo reticularis, purpura, petechiae, nodules, and deep ulcers are typically caused by vasculitis of deeper, medium, or large vessels. Biopsy is required for diagnosis. Treatment is influenced by the etiology and severity of the disease.
