Vitiligo patients will find white spots on their skin, but here the skin to
maintain the normal structure, and the affected area without itching or other
symptoms. Especially in the sun where the sun is particularly evident, including
the hands, feet, arms, legs, face, lips and so on. Some of the other areas prone
to white spot is generally armpit, groin, mouth around, eyes, nostrils, navel,
genitals and so on. Vitiligo is generally present in three ways. Some
pigmentation is seen only in small areas, and only in the unilateral body
(segmental vitiligo), but most of the patients are in all parts of the body
Vitiligo), and is generally symmetrical. In addition, some patients white spots
will be white hair, and even affect the color of the eye or the retina, causing
cataracts and other complications.
White surface is smooth without dander, white was pale white or milky white, if the border blurred or spread to normal skin, then there may be vitiligo. Vitiligo is a result of melanoma cells due to significant reduction or loss caused by skin, mucous membranes and hair pigmentation disease. Vitiligo pathogenesis is more complex, including autoimmune theory, melanoma cell destruction theory, neurochemical factor theory, genetic factors, trace elements and mental factors, microcirculation, diet, mood, alcohol and tobacco, drug stimulation, mechanical stimulation , Surgery, trauma, and so on the role of a variety of incentives
Gender was no significant difference, the age group can be the disease, but the young people good hair. Skin lesions for the pigment off the spot, often milky white, but also for the light pink, smooth surface without rash. White spot clear state, the edge of the pigment than normal skin increased, white hair within the normal or white. Lesions occur in the sun exposure and friction damage parts, lesions and more symmetrical distribution. White spots are often arranged according to the distribution of nerve segments were banded. In addition to skin damage, the lips, labia, glans and foreskin medial mucosa are often affected.
The disease more than no symptoms, a small number of patients before the onset or at the same time the affected area of local itching. Vitiligo often accompanied by other autoimmune diseases, such as diabetes, thyroid disease, adrenal insufficiency, scleroderma, atopic dermatitis, alopecia areata and so on. Specific types are as follows:
1. Limit type
(1) focal type of one or more white spots confined to a region, but not a segmental distribution;
(2) unilateral (segment type) one or more white spots were segmental distribution, in the midline suddenly disappeared;
(3) mucosal type only involving the mucosa.
2. scattered type
(1) the type of widespread and scattered in the distribution of white spots;
(2) facial acral distribution in the face and limbs;
(3) mixed type segment, facial acral and / or unusual mixed distribution.
Generalized
All or almost all of the pigment is lost.
More than 90% of vitiligo is scattered in the type of vitiligo in the rest of the type of more than the general type.
According to the lesion of pigment loss can also be divided into complete and incomplete disease of the two. The former pair of dihydroxy phenylalanine (DOPA) reaction is negative, melanocytes disappear, poor response to treatment. The latter response to DOPA positive, melanocytes did not disappear only the number of reduction, the probability of cure.
