Ichthyosis vulgaris

Ichthyosis vulgaris (also known as "Autosomal dominant ichthyosis," and "Ichthyosis simplex") is a skin disorder causing dry, scaly skin. It is the most common form of ichthyosis, affecting around 1 in 250 people. For this reason it is known as common ichthyosis. It is usually an autosomal dominant inherited disease (often associated with filaggrin), although a rare non-heritable version called acquired ichthyosis exists.
