Small white spots are more obvious show at hands leg arm and face lips part because these part are at exposure to sunlight. Some other regions are easily to have white patches such as armpit, around mouth, eyes, and nose, and belly button, private area. The vitiligo always appear in three ways, the first way is the white spot only confined in certain part. Some of it on one side of body it known as segmental vitiligo type.

One of the most important points is if there is any family history of this disease, and whether there is any dermexanthesis sunburn or other skin injury at the vitiligo patient’s skin lesion part before two to three months. Whether patients are have some physical disease and stress, whether there are some white hair are appearing. Except that the doctor should know about the patients and family members if sensitive to sunlight or with an autoimmunity disorder disease.

Such as they will do a biopsy examination to the abnormal part of tissue, and have a blood test to examine the blood amount and the thyroid function. Surely the doctor will also use the wood lamp to examine skin. All these tests will rule our other conditions.
