Psoriasis Of Nails
Psoriasis can affect the nails in up to 50 percent of patients, and this number can be higher if psoriatic arthritis is present. Some people might have only nail psoriasis with no apparent skin changes on the rest of the body. Psoriasis of the fingernails is more common than psoriasis of the toenails. Several changes can occur in the nail with psoriasis.
Discoloration: The nail can develop a yellow-brown discoloration that might involve the entire nail. The discoloration can also occur in only one or a few localized areas in a spot-like manner and resemble an oil droplet.
