RT Journal Article SR Electronic T1 Jaw claudication in primary amyloidosis: unusual presentation of a rare disease. JF The Journal of Rheumatology JO J Rheumatol FD The Journal of Rheumatology SP 2283 OP 2286 VO 30 IS 10 A1 Churchill, Christopher H A1 Abril, Andy A1 Krishna, Murli A1 Callman, Mark L A1 Ginsburg, William W YR 2003 UL http://www.jrheum.org/content/30/10/2283.abstract AB We describe two patients with temporal artery biopsy-proven amyloidosis presenting with symptoms of jaw claudication, visual disturbance, and proximal muscle stiffness suggestive of giant cell arteritis (GCA) and polymyalgia rheumatica. At the onset of disease, neither patient had other characteristic symptoms to suggest primary amyloid. We point out similarities between GCA and primary amyloid that can lead to confusion in diagnosis.
