White spots appeared on the areas exposed to the sun, hand feet, arm, face and neck etc are called vitiligo. Vitiligo is a skin condition or one say a skin disease in which melanin (pigmenting substance responsible for skin color) production disturbed.
Some time vitiligo is called pigmentation disorder in the human skin. The human skin contains special skin cells called melanocytes. Actually these cell t produce the pigment melanin which provide color of the skin. When melanocytes and mucous membranes tissues that is situated inside the mouth, nose, genital and rectal areas and the retina of the eyes are destroyed resulting the white patches of vitiligo.
These white patches of skin may appear on different parts of the body. Vitiligo may also causes the turn of color of hairs into white above the area affected by vitiligo.
Vitiligo has a close relation with autoimmune system of the body, and it is not wrong if we say that vitiligo is a common anomaly of the immune system that result in white spots on in the body. Case study shows that there are currently no acceptable permanent means to halt this process and exact reason of vitiligo is unknown. When we talk about the cure of vitiligo, we deals with eliminating the white spots weather root cause is addressed or not.
Today there are dozens of different methods in used for the treatment of vitiligo but there in no exact theory regarding the causes of vitiligo. One famous theory says some toxic material produced in the body which destruct the melanocytes cells.
Sunburn is a common symptom of vitiligo.
Types of Vitiligo
There are many types of vitiligo under the two main types.
1. Localized Vitiligo
Focal pattern vitiligo
In focal vitiligo a single patch on face, hand or leg with no other occurrences of disease on other body parts.
A light topical treatment is enough for the cure of focal pattern vitiligo and also small cosmetic surgery and tattooing are enough for such vitiligo.
Segmental pattern vitiligo
It is often called Lip Tip vitiligo because it is mostly limited to lips , distal parts of the fingers and toes. It is most difficult to treat segmental vitiligo.
Segmental vitiligo has quasi-dermatomal pattern with one or more spots. These patches are of irregular shap and asymmetric in distribution.
One or more patches are distributed within the same segment (anatomical distribution of the body) of the body.
2.Generalized Vitiligo
Acrofacial vitiligo
Acrofacial vitiligo is very common distribution of the disease in this type of vitiligo the white spot are restricted to parts away from the center of the body.
Affecting distal extremities and face. Some patches on face and some on other body parts, but not on all over the body.
the disease effects the exposed parts of the body such as head , face , feet and hand, therefore it also causes the great emotional distress.
Vulgaris Vitiligo
Due to wide spread it may take long time for treatment and normally it is not easy to treat this type of vitiligo. Also surgery may not be an option for patients of vitiligo vulgaris.In vitiligo vulgaris small patches of vitiligo are spread in a pattern like shower admixed with normal skin in segmental or acrofacial pattern.
This is the most common type with bilaterally symmetrical lesions, predominantly distributed over face, neck, torso, fingers, toes, palms, soles and facial orifices.
Universal vitiligo
It is also called vitiligo totalis, this type of disease cover almost all the body except some parts of the body like islands. Only choice for the treatment is permanent medical bleaching.
