Brief summary

Temporal artery biopsy is a useful tool helping to the diagnosis of giant cell arteritis. However, other diagnoses might be associated with abnormal temporal artery biopsy. The purpose of this study is to describe the frequency of giant cell arteritis differential diagnoses with positive temporal artery biopsy.
