Vitiligo is a skin
disease often forms on both sides of the body. It causes the skin to lose
color. Patches of lighter skin appear. Some people develop a few patches.
Others lose much more skin color. Vitiligo
is considered an autoimmune disease that causes body defense mechanisms to
destroy pigment, forming melanocytes in the skin, resulting in disfiguring
white patches. The destruction of these cells often extends to mucous membranes
and may affect the eyes, mouth, nose, and ears, as well as genitals. It affects
people of any ethnicity and may develop at any age, although the majority of
patients develop it before the age of 21.
Diagnosis
Proper diagnosis is the first step toward preventing further
damage and restoring color to the affected areas. Identification is commonly
based on the visual pattern and location of depigmentation, family history, and
ancillary symptoms. Your doctor may perform a simple examination. If other
symptoms indicate a need for it, a needle biopsy and a blood test may be
required to evaluate possible aggravating factors of vitiligo such as thyroid
disease, or low vitamin D.
There are two types of vitiligo—one is the common form of
generalized vitiligo affecting the entire body. The second type, known as
segmental, affects only one side of the body. Then, there is a subgroup called
marginal vitiligo. It appears with raised borders and a scattered pattern of
depigmentation. All pigment is lost in the other subtype, called universal, which
is a rare condition.
Symptoms
Most patients seek professional help when pale pink or white areas
appear on their skin. They often complain of first having an itchy feeling in
the location where the spots appear. The vitiligo spots don’t cause pain and may
not spread to another area for months or even years. Patients may have other
symptoms that are related to autoimmune disorders or diseases, as well.
Treatment
Vitiligo is not contagious. It is
not life-threatening. But, vitiligo can be life-altering. Some people develop
low self-esteem. They may no longer want to hang out with friends or develop
serious depression. Most people have vitiligo for life, so it’s important to
develop coping strategies. For years, vitiligo treatments were limited to
basic comfort measures and a few topical ointments. Thanks to a surge in
research, new treatments have proven successful in limiting the spread of the
disease and restoring color to depigmented areas that are sustained for up to
one year. Not all skin responds the same or lasts as long. It is individualized
both in therapy and results.
Recent studies show specific supplements, such as selenium, may be
recommended by your dermatologist. Surgical interventions have been employed,
such as skin grafts or even tattooing the color back in the whitened area. Your
dermatologist will determine the best line of care for your form of vitiligo.
