We report a case of polyarteritis nodosa with a clinical presentation mimic
king polymyalgia rheumatica, as well as pathological findings of non-giant-
cell arteritis on temporal artery biopsy with symptoms of jaw claudication.
Although certain clinical syndromes have been attributed to specific types
of systemic vasculitis, considerable overlap occurs. Obtaining issue biops
y in cases of vasculitis is mandatory for diagnosis and classification.
