Vitiligo is a disorder of pigmentation in human skin. The human skin contains special skin cells (melanocytes) that produce the pigment melanin that colors the skin.
In Vitiligo, the special skin cells (melanocytes) and tissues (mucous membranes) that line the inside of the mouth, nose, genitals and rectal areas and the retina of the eyes are destroyed. As a result, white patches of skin on different body parts. The hair may also turn white that grows in areas affected by vitiligo.
What causes vitiligo?
There are several theories about the cause of vitiligo, but the real cause is not fully known. By one theory, people with vitiligo develop antibodies that, turn on them and destroy their melanocytes rather tailored to protect them. There is another theory which melanocytes somehow attack and destroy themselves. Finally, some people with vitiligo have reported that a single event such as severe sunburn or an episode Emotional stress is the main cause of this order. Scientifically, events of this nature have not been accepted as the main cause of vitiligo. These are just coincidences.
Who is affected by vitiligo?
The number of people affected by vitiligo ( http://www.antivitiligo.com/vitiligo.html ) Rocks disorder from 40 to 50 million euros. Form 1-2% of people in the world. 2-5000000 people suffer from this disorder in the United States alone.

What is the association of vitiligo with autoimmune disease?
In autoimmune diseases, a person's immune system reacts against the body's own organs or tissues. Vitiligo is found to be more common in people with certain autoimmune diseases.
Autoimmune diseases associated with vitiligo include: hyperthyroidism (overactivity of the thyroid gland), adrenocortical insufficiency (the adrenal gland does not produce enough of the hormone corticosteroid), alopecia areata (patches of baldness), and pernicious anemia (low red blood cells caused by the failure of the body to absorb vitamin B12).
Is vitiligo hereditary?
Vitiligo may be hereditary in some cases. The children of vitiligo affected parents are more likely to develop vitiligo disorder. However, most children not have vitiligo even if a parent has. Also most people with vitiligo do not have family history of the disorder.

They are: ocular albinism type, autoimmune polyendocrinopathy syndrome, congenital deafness with vitiligo and achalasia, hereditary symmetric dyschromatosis, ermine phenotype, familial Reticulosis histiocyctic, Kabuki syndrome and paraparesis syndrome spastic, vitiligo, premature graying and characteristic facies.
The abundance of genetic diseases associated with vitiligo clearly proves that there are a number of genes that normally govern the development and welfare of melanocytes.
What are the symptoms of vitiligo?
White patches (depigmentation) in the skin are the main symbol of vitiligo. These patches are more common in sun-exposed areas, including the hands, feet, arms, face and lips. Other areas common are the armpits and groin, and around the mouth, eyes, nostrils, navel and genitals.
Vitiligo generally appears in one of three patterns: the pattern activity, segmental pattern and generalized pattern. In the pattern of activity, the depigmentation is limited to one or only a few areas. In segmental pattern, depigmented patches develop on only one side of the body. But in the generalized pattern, depigmentation occurs on different parts of the body.
