ichthyosis vulgaris [Gk, ichthys + osis + L, vulgaris, common] , a hereditary skin disorder characterized by large, dry, dark scales that cover the face, neck, scalp, ears, back, and extensor surfaces but not the flexor surfaces of the body. The condition is transmitted as an autosomal-dominant trait; it appears several months to 1 year after birth. Management consists of topical application of emollients and use of keratolytic agents to facilitate removal of the scales. Also called ichthyosis simplex. See also sex-linked ichthyosis.
