Clinical presentation as well as histological or biological findings can sometimes make the diagnosis of giant cell arteritis difficult. Histopathological features of temporal artery biopsy from giant cell arteritis patients are also challenging because of the various described appearances or even finding of clinically normal temporal artery biopsy does not rule out the diagnosis. We here describe the case of a 51-year-old man with temporal artery biopsy showing lymphocytes infiltrates in the adventitia corresponding to the so-called adventitial pattern of giant cell arteritis according to Hernandez-Rodriguez et al.
Keywords: adventitial pattern; giant cell arteritis; temporal artery biopsy.
