The mean age at onset was 6.1 \u00b1 3.7 years. Nails were involved in 32.3% of children. The main clinical aspects were pitting (69.1%) for fingernails and onycholysis (40.0%) and pachyonychia (27.5%) for toenails. All of the fingers were involved at similar frequencies, whereas the big toe was involved twice as often as the others (p &lt; 0.005). Nail involvement was associated with male sex (p &lt; 0.001), palmoplantar psoriatic (p &lt; 0.001), severity of disease (p = 0.003), and psoriatic arthritis (p = 0.03).<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusion<\/jats:title><jats:p>The prevalence of nail involvement was 32.3% in children with psoriasis.
