Ichthyosis

Ichthyosis is a family of dermatologicalconditions. Its literal translation is "fishskin", since people with ichthyosis have scaly skin which can vaguely resemble the scalesof a fish. The conditions are caused by geneticabnormalities.

The term ichthyosis is sometimes used to mean the specific condition ichthyosis vulgaris.

Ichthyosis was formerly referred to as "pseudo-leprosy," as it can produce an appearance superficially similar to that of leprosy.

Types

Some types of ichthyosis include:

• Ichthyosis vulgaris
• Ichthyosis lamellaris
• X-linked ichthyosis
• Epidermolytic hyperkeratosis
• Ichthyosis acquisita
• Harlequin type ichthyosis
• Netherton's syndrome
• Sjögren-Larsson syndrome

Diagnosis

A doctor usually can diagnose ichthyosis by looking at the skin. A family history is also very useful. In some cases, a skin biopsy will be done to help to confirm the diagnosis. In a biopsy, a small piece of skin is removed and examined under a microscope. In rare instances, genetic testing may be helpful in making a diagnosis. Ichthyosis is not more or less common in any ethnic group. There is no way to prevent ichthyosis.

Treatments

Treatments for ichthyosis often take the form of topical application of creams and oils, in an attempt to hydrate the skin. Retinoidsare also used for some conditions.
