Chapter 2 - Nail Psoriasis

Abstract

Prevalence of nail psoriasis ranges from 7% to 56%, in psoriatic patients and significantly burdens quality of life. Nail psoriasis is often associated with psoriatic arthritis. Clinical features present due to inflammation of either the nail matrix or the nail bed and include pitting, leukonychia, red spots in the lunula, crumbling, onycholysis, splinter hemorrhages, subungual hyperkeratosis, and oil-drop salmon patches. Management of nail psoriasis should be individualized, and this depends on the number of nails affected, involvement of skin and/or joints, that might affect the choice of topical or systemic therapies.
