Vasculitis with eosinophilia and digital gangrene in a patient with acquired immunodeficiency syndrome.

Fewer than 40 cases of vasculitis have been described in the setting of human immunodeficiency virus infection. We describe a patient with the acquired immunodeficiency syndrome (AIDS), a heavy smoker, who developed a syndrome of constitutional symptoms, eosinophilia and digital gangrene. Vasculitis of the digital arteries was documented by angiography. He responded to high dose corticosteroid therapy with arrest of the ischemic process. After steroids were discontinued, he suffered a relapse of the vasculitis documented by skin biopsy. In patients with AIDS with this serious, potentially steroid responsive condition, steroid therapy should be considered in spite of the preexisting immunodeficiency state.
