Skin manifestations are the most characteristic findings of psoriasis, however, nail psoriasis is often overlooked despite its common occurrence.^1,2 Nail involvement occurs in 61% of cases of cutaneous psoriasis and with a lifetime incidence among patients with psoriatic arthritis between 80% and 90%. About 1–5% of patients manifest with nail changes only.^4,5
