Nail involvement is found in 6.8-49.4% of patients and most commonly is seen in patients with severe forms of alopecia areata. Pitting is the most common finding. Several other abnormalities have been reported (eg, trachyonychia, Beau lines, onychorrhexis, onychomadesis, koilonychia, leukonychia, red lunulae). Fingernails predominantly are affected.
