title: [Intra-ungual linear opacities in psoriasis. Apropos of 10 cases].
abstract: Out of 145 patients with psoriasis, the authors observed in 10 cases linear opacities within the nails. They were not found in 128 controls of the same age. The routine was of X-ray films without a screen permitted their demonstration. These radio-opaque lines found in psoriasis may be the result of topical substances applied to the keratin of the psoriatic nail.
