Psoriatic onychodystrophy

Psoriatic Onychodystrophy is a condition that affects the nails of individuals suffering from psoriasis. It is characterized by changes in the nail's appearance, including discoloration, pitting, and thickening.

Symptoms

The symptoms of psoriatic onychodystrophy can vary, but often include:

• Nail discoloration: The nails may become yellow-brown.
• Nail pitting: Small dents or pits appear on the surface of the nails.
• Onycholysis: The nails may separate from the nail bed.
• Subungual hyperkeratosis: A chalky white material accumulates under the nail.
• Nail thickening: The nails may become thick and hard.

Causes

Psoriatic onychodystrophy is caused by psoriasis, a chronic skin condition. The exact reason why psoriasis affects the nails is not fully understood, but it is thought to be related to inflammation in the nail bed.

Diagnosis

Diagnosis of psoriatic onychodystrophy is usually based on the characteristic appearance of the nails. In some cases, a nail biopsy may be performed to confirm the diagnosis.

Treatment

Treatment for psoriatic onychodystrophy focuses on managing the symptoms and includes:

• Topical treatments: These are applied directly to the nails and may include corticosteroids, vitamin D analogues, or tazarotene.
• Systemic treatments: These are taken orally or injected and may include methotrexate, cyclosporine, or biologic therapies.
• Nail care: Keeping the nails short and avoiding injury can help reduce symptoms.
