Late-onset alopecia areata: Descriptive analysis of 30 cases

Alopecia areata is an autoimmune disease characterized by non-scaring hair loss. the onset in over 50-year-old patients is rare and has barely been studied. cases of this disease have been retrospectively analyzed – according to clinical forms,extension,and associated diseases – to assess alopecia areata characteristics in a group of patients whose disease onset was after the age of 50. 30 patients were studied; a few of them presented with autoimmune-related diseases or family history. the disease onset after the age of 50 seems to have different characteristics from those found in young people. ©2016 by anais brasileiros de dermatologia.
