Pictures of nail psoriasis are available online at Healthline.com, eMedicineHealth.com and PAPAA.org, the official website of the Psoriasis and Psoriatic Arthritis Alliance. In addition to nail psoriasis pictures, these resources offer information on nail psoriasis diagnosis, symptoms and treatment.
Nail changes caused by nail psoriasis include pitting of the nails, onycholysis, subungual hyperkeratosis and onychomycosis, according to the Psoriasis and Psoriatic Arthritis Alliance. The number of nail pits a person with nail psoriasis develops varies from patient to patient, and the pits can be shallow or deep, explains Healthline. Onychomycosis occurs when the nail separates from the nail bed, leaving an empty space underneath the nail. In subungual hyperkeratosis, chalky material accumulates under the nail, causing tenderness and discomfort, states the Psoriasis and Psoriatic Arthritis Alliance.
Nail psoriasis often causes nails to change color, notes Healthline. Some sufferers develop yellowish-brown nails, while others notice a yellowish-red discoloration in the nail bed. Additionally, some patients develop Beau lines across their nails or experience nail crumbling.
Psoriasis of the nails is incredibly difficult to treat, states the Psoriasis and Psoriatic Arthritis Alliance. Although results are inconsistent, rubbing topical steroids into the cuticle sometimes improves nail psoriasis symptoms. Other treatment options include injecting steroids under the affected nail or removing the nail. Patients with nail psoriasis should keep their nails trimmed short.
