Management of Nail Psoriasis

Nail psoriasis is a chronic nail disorder that requires personalized treatment. General prophylactic measures are suggested for all patients. Topical treatment is considered when treating a few-nail disease, with involvement of 3 or fewer nails, without joint involvement and without (or with mild) skin psoriasis. The ideal formulation should be ointment, solution, or foam. When moderate to severe skin psoriasis or psoriatic arthritis coexists, systemic treatment is suggested. This also should be considered when more than 3 nails are affected or significant impairment of quality of life is present. Conventional systemic agents, biologics, and small molecules are highly efficacious.
