What is Vitiligo?<\/h1>

Vitiligo is an autoimmune condition that causes the loss of skin color in blotches. With vitiligo, the sistema inmunol\u00f3gico<\/a> attacks and destroys melanocytes<\/a>, which are the cells responsible for skin pigmentation. When melanocytes are destroyed, the skin loses its color and white patches appear. These patches can occur anywhere on the body, but commonly affect areas like the face, hands, arms, feet, and lips.<\/p>

The appearance of vitiligo<\/a> is different for each person. For some, it starts as a small white spot that slowly spreads. Others may experience a more rapid loss of skin pigment resulting in larger patches. The patches may be localized to one part of the body or spread across large areas. The condition is not life-threatening or contagious, but can have emotional and psychological effects due to its visible symptoms affecting appearance. There is no cure for vitiligo, but several treatment options are available to help manage it. The goal of treatment is to stop progression and restore some of the lost skin color.<\/p>

Symptoms of Vitiligo<\/h2>

The main symptom of vitiligo is the appearance of patchy loss of skin color. The patches of de-pigmented skin<\/a> are initially small, but often grow and change shape over time. The patches can appear anywhere on the body, but are most commonly seen on sun-exposed areas like the face, neck, hands, arms and lips.<\/p>

The loss of skin pigment is particularly noticeable on darker skin. The affected skin patches start off as pale white at first. Over time, the white patches may become larger and spread to other areas. The borders of the white patches are often sharply defined at first, but may become irregular over time. The white patches may also appear on hair, the inside of the mouth or nose, and even the eyes.<\/p>

In addition to white patches on the skin, people with vitiligo may experience premature graying of scalp hair<\/a>, eyelashes, eyebrows and beard. Loss of color in the tissues lining the inside of the mouth and nose, and the retina of the eyes is also possible.<\/p>

What Causes Vitiligo?<\/h2>

Vitiligo is caused by the loss of melanin<\/a>, the pigment that gives skin its color. Melanin is produced by melanocytes<\/a>, specialized cells found in the epidermis (outer layer of the skin). In vitiligo, the melanocytes are destroyed, leading to depigmented patches on the skin.<\/p>

The exact cause of melanocyte destruction is unknown, but research suggests it’s an autoimmune disorder. This means the body’s immune system mistakenly attacks the melanocytes. Antibodies directed against pigment cells have been found in the blood of people with vitiligo.<\/p>

Other theories include oxidative stress damaging the melanocytes, and a genetic predisposition to vitiligo. Triggers like sunburn, stress, or exposure to industrial chemicals may also set off the condition in susceptible individuals. Overall, vitiligo is considered a multifactorial disease with genetic, immune, and environmental factors involved.<\/p>

Diagnosing Vitiligo<\/h2>

Diagnosing vitiligo<\/a> involves a physical exam, medical history, and blood tests.<\/p>

Physical Exam<\/strong><\/p>

During a physical exam, a dermatologist will examine the skin, looking for depigmented patches<\/a>. They will note the location, size, shape and extent of the discoloration. The doctor will also check for signs of inflammation or if the skin feels different in the discolored patches. They will look for poliosis, which is the loss of color of the hair in those areas.<\/p>

Medical History<\/strong><\/p>
