Nail changes in alopecia areata: Case report and review of the literature

A 54-year-old man was referred to our nail clinic with ridging of his fingernails. He was diagnosed with alopecia areata (AA) one year prior to the nail changes. His hair loss progressed rapidly, with loss of all scalp, facial and body year within a month. Physical examination was significant for severe ridging and trachyonychia of all his fingernails, without toenail involvement. A nail biopsy was performed. Histologic examination revealed abnormal keratinization of the nail plate with superficial matrical dyshesion and premature dyskeratosis.
