The clinical and histological characteristics as well as the genetic study of 4 cases of ichthyosis are presented. They were clinically classified as follows: laminar ichthyosis, 2 cases with recesive autosomal inheritance pattern; Hystrix ichthyosis, 1 case with dominant autosomal inheritance pattern; ichthyosis linked to X, 1 case with recesive inheritance pattern. The microscopic study showed hyperkeratosis in one of the cases of laminar ichthyosis, with reduction of the granulose layer in some zones and abcense of this in others. In the other case, the lesion has a psoriasiform aspect with hyperkeratosis, parakeratosis, and Munro's microabscesses. In Hystrix ichthyosis it was observed an epidermolytic hyperkeratosis; whereas in the ichthyosis linked to X it was found a hyperkeratosis with normal granulose layer.
