Nail Psoriasis

Clinical findings vary and are related to the specific areas of nail matrix involvement. Pitting, onycholysis (separation of nail from nail bed), subungual debris, oil drop sign, and nail dystrophy may occur. Nail findings offer supporting evidence of the diagnosis when skin changes are equivocal or absent.
