AbstractAlopecia areata is a non-scarring hair loss that commonly presents on the scalp. In men, when this condition results in facial hair loss on the cheek, jaw, and neck, it is referred to as beard alopecia areata. Beard alopecia areata can be associated with autoimmune conditions, such as diabetes mellitus, thyroid disorders, and vitiligo. A 28-year-old man presented with a five-month history of facial hair loss; his condition was diagnosed as beard alopecia areata after clinical examination. Treatment with twice daily topical 0.1% triamcinolone acetonide cream led to complete regrowth of his beard hair after six months. There are several potential agents and modalities for the treatment of individuals with beard alopecia areata. Treatment options include corticosteroid therapy (intralesional or topical), immunotherapy, Janus kinase (JAK) inhibitors, lasers, photodynamic therapy, platelet-rich plasma therapy, and treatment of an underlying Helicobacter pylori infection. Laboratory evaluation, prompted by our patient's diagnosis of beard alopecia areata, suggested incipient diabetes mellitus and nascent thyroid disease; specifically, he had elevated fasting blood glucose and elevated thyroid-stimulating hormone levels. Therefore, in patients with beard alopecia areata, laboratory evaluation for concomitant or incipient autoimmune diseases should be considered.Copyright © 2020, Forouzan et al.
