[Hypersensitivity vasculitis].

Abstract

Hypersensitivity vasculitis (HSV) is characterized by palpable purpura and arthralgia, the existence of precipitating factors(medications or infections), and leukocytoclastic vasculitis in the skin lesion. It is known by a variety of names, including leukocytoclastic vasculitis, cutaneous small-vessel vasculitis (CSVV), allergic vasculitis. Patients are classified as HSV according to the criteria proposed by a subcommittee of the American College of Rheumatology (ACR) in 1990. HSV is distinguished from Henoch-Schönlein purpura that has a higher risk of gastrointestinal and renal involvement. Systemic involvement in HSV is rare and its prognosis is excellent. Most cases in HSV are self-limited if the precipitant can be removed.
