Medical Definition of Ichthyosis vulgaris

Ichthyosis vulgaris: A genetic (inherited) skin disease characterized by dry, scaly areas of skin that usually appear in childhood. The palms and soles are often affected. Other possible symptoms include thickening and itching of the affected areas of skin. Areas that tend to be spared include the armpits, the insides of the elbows, and the skin behind the knee. Many people with ichthyosis vulgaris also have asthma, eczema, or hay fever. Treatment involves the use of creams and ointments to moisturize the skin. The gene responsible for this disease is located on chromosome 1. Also known as ichthyosis simplex or fish scale disease. Another, rare form of the condition develops in adults, is not inherited, and is related to underlying disease processes in the body including malignancy.
