A 79-year-old Japanese woman with temporal arteritis accompanied by Sjogren's syndrome proven upon histological examination was reported. A biopsy of the temporal artery showed typical findings of giant cell arteritis with deposition of IgG and C3 by and immuno-fluorescence study. A complication with latent peripheral polyneuropathy was also obseved. It is known that Sjogren's syndrome is often associated with connective tissue diseases, but a complication with temporal arteritis has rarely been reported.
