Fingernail psoriasis. Close-up of the finger of a 5-year-old child with psoriasis of the nail. Psoriasis is a common skin disease involving a large increase in the speed of epidermal (outer skin layer) cell production. Here,psoriasis has caused pitting of the nails. The nail keratin is poorly knit because of the accelerated growth. Growth may also be distorted,with the nails becoming thick and brittle,and the nails may also be loosened from their nailbeds. The cause of psoriasis is unknown but certain infections,drugs and stress are known to trigger attacks | |
