Alopecia Areata of the Beard: A Review of the Literature

The document from 2017 reviewed literature on Beard Alopecia Areata (BAA), a T-cell mediated autoimmune disorder causing hair loss in the beard area. It described the clinical presentation, typically affecting middle-aged males with focal patches of hair loss, and dermoscopic features such as yellow dots and broken hair. The review noted associations with other autoimmune disorders and discussed treatments like topical and intralesional corticosteroids, but emphasized the limited evidence for these treatments specifically for BAA. The document called for more research due to the scarcity of reports and lack of understanding of BAA's epidemiology, pathogenesis, and treatment. It also acknowledged the psychological impact of BAA and the potential for spontaneous remission. No conflicts of interest or funding were reported for the manuscript.
