Nail Psoriasis

Nail psoriasis refers to a condition where psoriasis, a chronic autoimmune skin disease, specifically affects the fingernails and toenails. It is characterized by various changes in the appearance of the nails, including pitting (small depressions or dents), onycholysis (separation of the nail from the nail bed), discoloration, crumbling, thickening, ridges, and overall nail deformation. Nail psoriasis can cause discomfort, pain, and difficulty in performing activities involving the hands or feet.
