ABSTRACT
Nail psoriasis occurs in up to 80% of patients with plaque psoriasis and is more prevalent in patients with psoriatic arthritis. Nail psoriasis is far more than just a cosmetic problem. Psoriasis of the fingernails is psychologically distressing and can cause pain, functional deficits in fine motor manipulation of small objects, and when toenails are involved, it can cause difficulty with ambulation. Although nail psoriasis can be extensively destructive to the nail plate, it is a nonscarring process. If treated effectively, nails with psoriasis can return to a normal or close to normal condition. Nail psoriasis takes a vast toll on patients, but with treatment and hopefully clearing of nail psoriasis the quality of life can greatly increase.
