Tocilizumab for giant cell arteritis: an amazing result

Giant cell arteritis (GCA), previously Horton’s disease, is a systemic vasculitis affecting the middle-sized or large arteries in patients older than 50 years of age. The mainstay of the treatment of GCA is glucocorticoid therapy. Herein, we present a case with giant cell arteritis resistant to oral and intravenous steroid, intravenous cyclophosphamide and mycophenolate mofetil, but successfully treated with tocilizumab.
