Dermatological manifestations associated with microscopic polyangiitis

Microscopic polyangiitis (MPA) is a systemic small vessel vasculitis, which, although primarily associated with necrotizing and crescentic glomerulonephritis and pulmonary capillaritis, often has cutaneous and musculoskeltal features. Although the skin is affected in 20–70% of patients, the precise description has been limited. This retrospective study analyzed clinical manifestations in patients of MPA with skin eruptions.
