    Objective: To study the epidemiology of biopsy- proven Giant Cell Arteritis (GCA) in an Arab population with clinical features suggestive of GCA.

    Methods: Clinical records of 102 patients who underwent temporal artery biopsy (TAB) at King Khaled Eye Specialist Hospital, Riyadh, Saudi Arabia from January, 1983 to December, 2004 were reviewed.

    Results: Among the 56 males and 46 females, 7 (6.8%) had biopsy-proven GCA. The mean age of biopsy- positive group (71.7 +/-8.6 years) was higher than in the biopsy-negative group (65 +/-9.8 years; p =0.005). None of the untreated patients with a negative TAB developed additional symptoms typical of GCA.

    Conclusion: The small absolute number of biopsy- proven cases of GCA implies a relatively low incidence of GCA in Arab population, confirming previous observations that GCA occurs primarily in the Caucasian population.
