Abstract

Ichthyosis is clinically characterized by the existence of visible flakes on the skin. The four main hereditary ichthyosis are: ichthyosis vulgaris autosomal dominant transmission, X-linked ichthyosis, lamellar ichthyosis, and congenital ichthyosiform necrolysis. At birth, the ichthyosis can be unapparent or realize collodion baby or Harlequin fetus. The Harlequin fetus is the most severe form and usually lethal ichthyosis. It is transmitted as an autosomal recessive. This is clinically a rare form of skin disease with large, thick, and yellowish scales, separated by deep red crevices giving the appearance of a baby frog. We here review a rare form of Harlequin fetus admitted to the neonatal unit at day 1 of life.
