定义 英文原文（暂无中文）

A rare secondary vasculitis characterized by inflammation of blood vessels caused by various drugs, including antibiotics, anti-tumor necrosis factor-alpha agents, immunotherapeutic drugs, and psychoactive agents, among others. The skin is most commonly affected, but other tissues and organs, such as the subcutis, kidneys, or lungs, may also be involved. Systemic disease develops only in a minority of patients, typically when treated with the causative drug over a prolonged period of time.
