title: Reticulated lesion as an early diagnostic sign for giant cell arteritis.
abstract: We report a case of giant cell arteritis (GCA) in an elderly woman. The patient presented to her dermatologist with a reticulated, purpuric patch on her frontal-temporal scalp and forehead that was associated with unilateral head pain. A punch biopsy of the lesion was suspicious for GCA, which was later confirmed by temporal artery biopsy. This case highlights a potential early cutaneous finding of GCA that may aid the clinician in the diagnosis before more severe complications occur.
