ichthyosis ich·thy·o·sis (ĭk'thē-ō'sĭs)
A congenital, often hereditary skin disease characterized by dry, thickened, scaly skin. Also called alligator skin, fish skin, fishskin disease, ichthyosis sauroderma.
a hereditary condition involving dryness and scaliness of the skin brought about by excessive growth of the horny outermost covering of the skin. The dead cells of this horny layer do not slough off at the normal rate but tend instead to adhere to the skin surface to form scales; horny plaques and papules may also be present in more severe cases. The skin in this condition is intolerant of even the mildest irritants and is prone to severe chapping and fissuring in cold weather. Ichthyosis is usually not detected at birth, but, as the child grows older, dry branny scaling will appear, being most marked on the extensor surfaces of the extremities. Ichthyosis may sometimes be associated with a deficiency of the sweat glands and, less frequently, with irregularities in the growth of hair, teeth, and nails. In its mild and simplest form, ichthyosis is probably the most common of the hereditary skin disturbances.
