It is characterized at birth by the presence of large, thick, plate-like scales over the whole body associated with severe ectropion, eclabium, and flattened ears, that later develops into a severe scaling erythroderma. Affected infants born encased in a collodion membrane taut, shiny, translucent membrane appearing as an extra skin layer with armorlike plates, distributed throughout the body, which severely restrict movement. Facial features are distorted due to extreme ectropion, conjonctival edema, eclabium and broadened nose.

Ichthyosis is a family of genetic skin disorders characterized by dry, thickened, scaly skin. The severity of symptoms can vary enormously, from the mildest, most common, types such as ichthyosis vulgaris , which may be mistaken for normal dry skin, up to life-threatening conditions such as harlequin-type ichthyosis. Many types of ichthyoses exist, and an exact diagnosis may be difficult. Types of ichthyoses are classified by their appearance and their genetic cause.

Ichthyosis caused by the same gene can vary considerably in severity and symptoms. Some ichthyoses do not appear to fit exactly into any one type. Different genes can produce ichthyoses with similar symptoms. The most common or well-known types are: [5]. A physician often can diagnose ichthyosis by looking at the skin. A family history is very useful. In some cases, a skin biopsy is done to help to confirm the diagnosis.

In some instances, genetic testing may be helpful in making a diagnosis. Diabetes has not been definitively linked to acquired ichthyosis or ichthyosis vulgaris; however, there are case reports associating new onset ichthyosis with diabetes. Ichthyosis has been found to be more common in Native American, Asian, Mongolian groups.

There is no way to prevent ichthyosis. Ichthyosis is a genetically and phenotypically heterogeneous disease that can be isolated and restricted to the skin manifestations or associated with extracutaneous symptoms. One of which is limb reduction defect known as CHILD syndrome ; a rare inborn error of metabolism of cholesterol biosynthesis that is usually restricted to one side of the body.

A research done in Egypt proved that it is not a child syndrome and discussed all the case report. Treatments for ichthyosis often take the form of topical application of creams and emollient oils, in an attempt to hydrate the skin. Creams containing a high percentage of urea or lactic acid have been shown to work exceptionally well in some cases. Retinoids are used for some conditions. Exposure to sunlight may improve [ citation needed ] or worsen the condition.

In some cases, excess dead skin sloughs off much better from wet tanned skin after bathing or a swim, although the dry skin might be preferable to the damaging effects of sun exposure. There can be ocular manifestations of ichthyosis, such as corneal and ocular surface diseases. Vascularizing keratitis , which is more commonly found in congenital keratitis-ichythosis-deafness KID , may worsen with isotretinoin therapy. Ichthyosis or ichthyosis-like disorders exist for several types of animals, including cattle, chickens, llamas, mice and dogs.

The most common breeds to have ichthyosis are Golden retrievers , American bulldogs , Jack Russell terriers and Cairn terriers. From Wikipedia, the free encyclopedia. Ichthyosis Other names Ichthyoses Ichthyosis is characterized by rough, scaly skin.

Ichthyosis

Ichthyosis vulgaris develops when skin cells fail to shed normally and instead accumulate in thick, dry scales. People with darker skin tend to have darker colored scales, as shown here. Ichthyosis vulgaris ik-thee-O-sis vul-GAY-ris is an inherited skin disorder in which dead skin cells accumulate in thick, dry scales on your skin's surface. The scales of ichthyosis vulgaris, sometimes called fish scale disease or fish skin disease, can be present at birth, but usually first appear during early childhood. Sometimes, mild cases of ichthyosis vulgaris go undiagnosed because they're mistaken for extremely dry skin.
