Cutaneous vasculitis: a rheumatologist perspective.

Cutaneous vasculitis (CV) comprises a wide spectrum of diseases and displays a variety of clinical lesions, the most common being a palpable purpura. CV may be a process confined exclusively to the skin or be a manifestation of a more widespread entity associated to a variable grade of visceral involvement. In this regard, CV may occur as part of the clinical spectrum of primary systemic vasculitis, autoimmune diseases or less commonly as presenting manifestation of cancer or severe infections. An adequate clinical approach is required to establish optimal management of this condition.
