Nonsteroidal antiinflammatory drug induced hypersensitivity vasculitis clinically mimicking temporal arteritis

Not all arteritides of the temporal arteries are giant cell temporal arteritis (Horton's disease). We describe an unusual case of etodolac (Lodine) nonsteroidal antiinflammatory drug (NSAID) induced hypersensitivity vasculitis of the temporal artery clinically simulating giant cell temporal arteritis. NSAID are common drugs and their gastrointestinal and renal side effects are well known. Ours is the first known documentation of NSAID induced hypersensitivity vasculitis isolated to the involvement of a temporal artery.
