Definition

Heterogeneous group of disorders characterized by a vasculitic syndrome presumed to be associated with a hypersensitivity reaction following exposure to an antigen such as an infectious agent, a drug, or other foreign or endogenous substance (Wilson et al, Harrison's Principles of Internal Medicine, 12th ed, p1459).
