Ichthyosis vulgaris, also known as common ichthyosis or fish scale disease, is a skin condition resulting in scaly skin, especially on the arms and legs. Its name is derived from the Greek word meaning “fish.”

Ichthyosis vulgaris can be a trait passed on in families (hereditary), or it may develop later in life as a result of certain exposures (acquired). The hereditary type, also called congenital ichthyosis vulgaris, first appears in early childhood and accounts for more than 95% of cases of ichthyosis vulgaris. The acquired type usually develops in adulthood and results from an internal disease or the use of certain medications.

Hereditary ichthyosis vulgaris tends to improve after puberty, while acquired ichthyosis vulgaris requires treatment of the medical condition before it will improve.
