Nail Psoriasis

This condition is very difficult to treat. Twenty-five percent or more of patients will also suffer from a fungal infection.

• A trial of topical corticosteroids, especially under occlusion
• Calcipotriol may show some benefit in subungual hyperkerastosis
• Intralasional triamcinalone 0.1ml of 2-5mg/ml injected into the nail matrix every 2-4 weeks helps the majority of people with this problem, but in 50% there are quick relapses when treatment is stopped
• 5-fluorouracil 1% twice a day to the nail margins reduces the severity of nail changes in two-thirds of nails over a 3-6 months
• Systemic therapy can be of benefit
