Association between histological features in temporal artery biopsies and clinical features of patients with giant cell arteritis.

Background: In most cases of giant cell arteritis (GCA) the diagnosis is confirmed by temporal artery biopsy. Aside from the diagnostic purpose, histological parameters may serve as prognostic markers.

Objectives: To review positive temporal artery biopsies ofGCA in an attempt to correlate various histological parameters with clinical features, disease complications and outcome.
