White spot on Skin

White spot on Skin



Overview

Vitiligo (pronounced “vit-il-EYE-go”) is a skin condition that causes your skin to lose its color or pigment. This causes your skin to appear lighter than your natural skin tone or turn white. Areas of your skin that lose their pigment are called macules if they’re less than 1 centimeter wide, or patches if they’re larger than 1 centimeter. If you have vitiligo on a part of your body that has hair, your hair may turn white or silver.

The condition occurs when your body’s immune system destroys melanocytes. Melanocytes are skin cells that produce melanin, the chemical that gives skin its color, or pigmentation.

Who does vitiligo affect?

Vitiligo affects all races and sexes equally. It’s more visible in people with darker skin tones. Although vitiligo can develop in anyone at any age, macules or patches usually become apparent before age 30.

You might be at a higher risk of developing vitiligo if you have certain autoimmune conditions like:

Addison’s disease.

Anemia.

Diabetes (Type 1).

Lupus.

Psoriasis.

Rheumatoid arthritis.

Thyroid disease.

What are the types of vitiligo?

Types of vitiligo include:

Generalized: This is the most common type of vitiligo that causes macules to appear in various places on your body.

Segmental: This type only affects one side of your body or one area, such as your hands or face.

Mucosal: Mucosal vitiligo affects mucous membranes of your mouth and/or genitals.

Focal: Focal vitiligo is a rare type where the macules develop in a small area and don’t spread in a certain pattern within one to two years.

Trichome: This type causes a bullseye with a white or colorless center, then an area of lighter pigmentation, and an area of your natural skin tone.

Universal: This rare type of vitiligo causes more than 80% of your skin to not have pigment.

Symptoms

Signs and symptoms of vitiligo include:

Patches of skin or mucous membranes that lose color. These can appear white or lighter than your natural skin tone.

Patches of hair on your body turn silver, gray or white.

Symptoms can be mild and only affect a small area of your body or severe and affect a large area of your skin. Some people with vitiligo experience itchy skin before depigmentation starts.

Where will I have symptoms of vitiligo?

Symptoms of vitiligo can appear anywhere on the skin of your body. The most common places to have symptoms of vitiligo include on your:

Hands.

Feet.

Arms.

Face.

Mucous membranes (inside of your mouth, lips and nose).

Genitals (penis).

What causes vitiligo?

A lack of pigment in your skin (melanin) causes vitiligo. The reason why this happens is unknown. Research suggests vitiligo could be the result of:

An autoimmune condition: Your immune system mistakes healthy cells (melanocytes) as foreign invaders like bacteria that can cause harm to your body. This makes your immune system overreact and develop antibodies to destroy your melanocytes.

Genetic changes: A genetic mutation or a change to your body’s DNA can affect how your melanocytes function. There are over 30 genes that can increase your risk of developing vitiligo.

Stress: The amount of pigment your melanocyte cells produce may change if you experience frequent emotional stress or physical stress on your body, especially after an injury.

Environmental triggers: Factors like ultraviolet radiation and toxic chemical exposure can affect how your melanocyte cells function.

Is vitiligo genetic?

While research is ongoing to learn more about the causes of vitiligo, studies indicate that about 30% of vitiligo cases are genetic. This means that the condition is hereditary and you could potentially inherit vitiligo from your biological family. Several possible genetic mutations affect how melanocyte cells function. If a genetic mutation targets the cells that give your skin pigment, you’ll experience symptoms of vitiligo.

Is vitiligo painful?

No, vitiligo isn’t painful. However, you can get painful sunburns on lighter patches of skin affected by vitiligo. It’s important to protect yourself against the sun with measures like using sunscreen, staying out of the sun during the hours that it’s strongest and wearing protective clothing.

Does vitiligo cause complications?

Although vitiligo is mainly a cosmetic condition, vitiligo may cause:

Sensitive skin: Macules and patches lack melanocytes, so your skin can be more sensitive to sunlight than the rest of your skin. This can cause your skin to quickly burn instead of tanning.

Eye abnormalities: People with vitiligo may have some abnormalities in their retinas (the inner layer of your eye that contains light-sensitive cells) and some variation of color in their irises (the colored part of your eye). In some cases, there’s inflammation of the retina or iris, but vision usually isn’t affected.

Predisposition to autoimmune conditions: People with vitiligo may be more likely to get other autoimmune conditions that affect how their body’s immune system functions. Common autoimmune conditions include hypothyroidism, diabetes and anemia.

Emotional challenges: People with vitiligo may feel embarrassed about the way their skin looks. Some people diagnosed with vitiligo develop low self-esteem. This could cause anxiety or depression and make someone want to isolate themselves or avoid social situations. If this happens, you should talk to your healthcare provider, a mental health professional or your family and friends.

Diagnosis

A visual examination by a healthcare provider usually leads to an accurate diagnosis of vitiligo. Your provider may use a Wood’s lamp to look at your skin. This lamp uses an ultraviolet (UV) light that shines onto your skin to help your provider differentiate vitiligo from other skin conditions. In addition, your provider may ask you questions about your medical history and family medical history.

What other conditions look like vitiligo?

There are other conditions that make your skin change or lose pigmentation, including:

Chemical leukoderma: Exposure to some industrial chemicals causes damage to skin cells, resulting in linear or splotchy white areas of skin.

Tinea versicolor: This yeast infection can create dark spots that show on light skin, or light spots that show on darker skin.

Albinism: This genetic condition means that you have lower levels of melanin in your skin, hair and/or eyes.

Pityriasis alba: This condition starts with red and scaly areas of skin, which fade into scaly lighter patches of skin.

Treatment

Treatment for vitiligo isn’t necessary, as the condition isn’t harmful to your body and is only cosmetic. If you have widespread vitiligo or your physical symptoms affect your emotional well-being, your healthcare provider can help you find a treatment option to create a uniform skin tone by either restoring color (repigmentation) or eliminating the remaining color (depigmentation) in your skin. Common treatments for vitiligo include:

Medications.

Light therapy.

Depigmentation therapy.

Surgery.

Counseling.

Medications

There isn’t a specific medication to stop vitiligo from affecting your skin but there are certain drugs that can slow the speed of pigmentation loss, help melanocytes regrow or bring color back to your skin. Medications to treat vitiligo could include:

Corticosteroids.

Topical Janus kinase inhibitors (ruxolitinib).

Calcineurin inhibitors.

Light therapy

Light therapy or phototherapy is the treatment to help return color to your skin. Your provider will use light boxes, ultraviolet B (UVB) lights or medical-grade lasers directed at your skin for a short amount of time. It can take several light therapy sessions to see results on your skin.

Combining oral psoralen medication and ultraviolet A light (PUVA) treats large areas of skin with vitiligo. This treatment is effective for people with vitiligo on their head, neck, trunk, upper arms and legs.

Depigmentation therapy

Depigmentation therapy removes the color of your natural skin tone to match areas of your skin affected with vitiligo. Depigmentation therapy uses the drug monobenzone. You can apply this medication to pigmented patches of your skin. This will turn your skin white to match the areas of your skin with vitiligo.

Surgery

Surgery is a treatment option for people diagnosed with vitiligo. Surgical treatment could include:

Skin grafts: Skin is taken from one part of your body and used to cover another part. Possible complications include scarring, infection or a failure to depigment. This might also be called mini grafting.

Blister grafting: Blister grafting uses suction to create a blister on your skin and your provider will then remove the top of the blister to attach it to an area of your skin affected by vitiligo.

Your healthcare provider might not recommend surgery if you:

Have quickly spreading vitiligo.

Scar easily.

Develop raised scars that grow larger than a wound (keloids).

Counseling

Some people diagnosed with vitiligo find counseling or visiting a mental health professional beneficial to help improve their self-esteem, anxiety or depression that can be associated with changes to their skin. Vitiligo can cause psychological distress and can affect a person’s outlook and social interactions. If this happens, your caregiver may suggest that you meet with a counselor or attend a support group.

Charge Syndrome

Overview CHARGE syndrome is a recognizable genetic syndrome with known pattern of features. It is an extremely complex syndrome, involving extensive medical and physical difficulties that differ from child to child. CHARGE syndrome is correlated with genetic mutation to CHD7 and the prevalence of CHARGE syndrome is 1:10,000-1:15,000 live births. Babies with CHARGE syndrome are often born with life-threatening birth defects. They spend many months in the hospital and undergo many surgeries and other treatments. Swallowing and breathing problems make life difficult even when they come home. Most have hearing two little girls sitting on a carpet, one girl has a trach and is biting her finger.loss, vision loss, and balance problems that delay their development and communication. Despite these seemingly insurmountable obstacles, children with CHARGE syndrome often far surpass their medical, physical, educational, and social expectations. One of the hidden features of CHARGE syndrome is the ...

Legg–Calve–Perthes disease

  Legg–Calve–Perthes disease Overview Legg-Calve-Perthes (LEG-kahl-VAY-PER-tuz) disease is a childhood condition that occurs when blood supply to the ball part (femoral head) of the hip joint is temporarily interrupted and the bone begins to die. This weakened bone gradually breaks apart and can lose its round shape. The body eventually restores blood supply to the ball, and the ball heals. But if the ball is no longer round after it heals, it can cause pain and stiffness. The complete process of bone death, fracture and renewal can take several years. To keep the ball part of the joint as round as possible, doctors use a variety of treatments that keep it snug in the socket portion of the joint. The socket acts as a mold for the fragmented femoral head as it heals. Symptoms Symptoms of Perthes disease include: Limping. Pain or stiffness in the hip, groin, thigh or knee. Limited range of motion of the hip joint. Pain that worsens with activity and improves with rest. Perthes diseas...

Landau-Kleffner Syndrome

  Landau-Kleffner Syndrome Overview Landau-Kleffner syndrome is a condition that affects your brain by causing seizures and a loss or decline in speech and language skills. Children with LKS have abnormal electrical signals in their brains that affect their ability to understand language and speak. LKS typically affects children, starting when they’re between 3 and 8 years old. But children as young as 2, as well as adolescents, can have the condition. Boys are more likely to have LKS than girls. If your child has LKS, they may lose their ability to speak and understand language (aphasia). This can happen rapidly all at once, or slowly. Many children with LKS — about 70% — also have seizures, often during sleep. Symptoms Not every child with LKS has the same symptoms. If your child has LKS, it may seem like they can’t hear you. They may have a hard time understanding what you and others say to them. They may also have new developmental delays, intellectual differences or learning d...
