Know About Vilitigo Depigmentation Condition & Treatment

Vitiligo, a common skin condition that causes white patches in skin. Vitiligo occurs due to the loss of melanin in skin. The production of melanin stops when the corresponding cells which produce the melanin dies. Melanin is the element which gives colour to our hair, skin and eyes. So any defect causing to these cells will affect our natural colour.

When this problem affect a person, it will spread from where it started. Normally it comes in areas of skin which is exposed to sun like hands, arms, legs, face, head etc. It can affect anybody or in any age. It is more noticeable to people who has Darker skin.

Symptoms & Causes


The common sign of vitiligo is the white patches appear on the skin. The other symptoms or signs are colour loss of tissues inside mouth, inner layer of eyes and whitening of hair in eyebrows, eyelashes etc. Vitiligo can come in any part of the body. Can affect the genitals also.

Causes of vitiligo is not known exactly but the doctors have several opinions. Vitiligo can be inherited because they inherit with a group of 3 genes and it is able to make de-pigmentation. Another view about vitiligo is that it is a autoimmune disease. In this the de-pigmentation occurs because the persons immune system reacts with body's own tissues. Yet another theory is that the melanocytes destroys themselves. 


Focal Pattern:- De-pigmentation appears in one part or a few areas.
Segmental Pattern:- De-pigmentation appears only in one part of the body.
Generalized Pattern:- De-pigmentation appears symmetrically in both sides of the body and is the most common pattern.

Diagnosis & Treatment


Diagnosis starts from physical examination, ask the patient about medical history and will write for laboratory test. The doctor will then tell what type of vitiligo is affected with the patient. There are two types of vitiligo.
Segmental vitiligo or Unilateral Vitiligo which will appear only in one segment of the body, most people lose their hair colour, it begins at early age and progresses for a year or stops.
Non segmental vitiligo is the second type of vitiligo. It is classified in to 3, they are Bilateral, Vitiligo vulgaris, Generalised vitiligo. These types are more common, appears on both sides of body, chances to get bigger and spread, will appear on wrists, hands, fingers, eyes, mouth etc.

We can't fully get rid of Vitiligo. The main aim is to improve the appearance of the skin. The therapies needs to be done for 6 to 18 months for better results. Each patient respond differently and one type of treatment may not work for everyone. The treatment procedure also change according to the size, location, the areas to which it spread etc.


Treatment options are,



- Medical Therapies

  • Topical Steroid Therapy:- Steroid creams are used to re-pigment the white patched skin. It is very effective when applied at the initial stage of disease.
  • Psoralen photochemotherapy:- PUVA therapy is the most effective treatment for vitiligo. This will also re-pigment the white patches. It is expensive & time consuming compared with other treatments and care must be taken to avoid side effects. There are two types of treatments coming under PUVA they are, Topical psoralen photochemotherapy and Oral psoralen photochemotherapy.
  • Depigmentation:- De-pigmentation treatment is done for person who have 50% vitiligo in their body. Because it is difficult to reverse the entire body to normal colour, so normal skin areas will be converted to match the de-pigmented colour. The de-pigmentation cream will be applied to normal areas of body. After the application of cream, for at least 2 hours the patient should avoid contact with others. If the cream spread in others their skin may get de-pigmented.

- Surgical Therapies  

 

Normally opted only if the medical therapies fail. Surgical therapies are more expensive & time consuming.
  • Autologous skin grafts:- In this method the doctor will remove skin from one area and grafts to the de-pigmented area. This method is opted when the patient have less vitiligo. There are several complications like both the donor and recipient will have scarring.
  • Skin grafts using blisters:- In this procedure the doctor will create blisters in the normal skin using heat, suction or freezing cold. Then top of blisters will cut out and transplanted to the de-pigmented area. It is better method because it cause less scar compared with others.
  • Micropigmentation:- This procedure involves implanting pigment into skin with a special instrument. It works well for dark skin and surrounding lip areas. It is difficult for doctors to match exact colour. Even it is matched, when exposed to sun and fade after some time and may mismatch.
  • Autologous melanocyte transplants:- In this procedure, the doctor may collect the patients normal pigmented skin and places in a special cell culture solution. Keep it more the multiplication of melanocytes. After it is multiplied, it is grafted to the de-pigmented areas. Currently this method is in experimental stage.
