Vitiligo is a disease that causes loss of skin color in patches. Usually, with time, the discolored areas get bigger. This condition can affect any part of your skin and the color of hair growing out of that part. It generally starts on the hands, forearms, feet, and face. Globally, about 1% or so of the population has vitiligo. The white patches are usually permanent. Vitiligo will not cause dryness or discomfort but the patches may occasionally be itchy.
Vitiligo is caused by the lack of a pigment called melanin in the skin. Melanin is produced by skin cells called melanocytes, and it gives your skin its color. When you have vitiligo, not having enough working melanocytes causes less production of melanin in your skin. Which will eventually cause white patches to develop on your skin or hair. The exact cause of melanocytes disappearing from these areas is not clear.
Vitiligo often starts as a pale patch of skin and gradually turns completely white. The center of the patch may be white, with paler skin around it. Also if a blood vessel is under the skin, the patch may be slightly pink, rather than white. The edges of the patch may be smooth or irregular.
Vitiligo is a chronic, non-contagious disorder characterized by the development of white patches on the skin. This condition arises when melanocytes, the cells responsible for producing the skin pigment melanin, cease to function or die off. Melanin is the compound that gives skin, hair, and eyes their color, so the absence of melanin in certain areas leads to depigmented white patches. These patches can appear anywhere on the body, including the skin, hair (leading to premature graying), and mucous membranes inside the mouth and nose.
The exact cause of vitiligo is still a subject of research, but it is widely believed to be an autoimmune condition where the immune system mistakenly attacks and destroys the melanocytes. Several factors may contribute to this, including genetic predisposition, environmental triggers, stress, and possibly exposure to certain chemicals. Vitiligo can affect individuals of any age, race, or gender, but the loss of pigmentation is more pronounced in people with darker skin tones.
There are different types of vitiligo, each with varying patterns of depigmentation. Generalized vitiligo, the most common form, typically presents with symmetrical patches on corresponding body parts. Segmental vitiligo, on the other hand, tends to affect only one side or part of the body and usually begins at a younger age. Universal vitiligo is a rare form where nearly all skin surfaces lose pigment. The progression of vitiligo is unpredictable—some may experience a halt in depigmentation without treatment, while others may see it spread to most of the skin. In some cases, the skin may spontaneously regain its color.
The psychological impact of vitiligo should not be underestimated, as it can lead to significant emotional distress, social stigma, and self-esteem issues. However, various treatment options are available to help manage the condition. While there is currently no cure for vitiligo, ongoing research continues to explore the mechanisms behind the condition and potential new treatments.
Vitiligo is a condition that transcends racial, ethnic, and gender boundaries, affecting approximately 1% of the global population. It can manifest in individuals of any age, but it is more commonly observed in those under the age of 30. The condition is characterized by the body's immune system attacking and destroying melanocytes, the cells that produce skin pigment, leading to the formation of white patches on the skin.
While vitiligo can affect anyone, it is often more noticeable and may have a greater psychological impact on individuals with darker skin tones due to the contrast between affected and unaffected areas. The condition does not discriminate based on sex; it affects both males and females equally. However, certain autoimmune diseases, such as Addison's disease, diabetes (Type 1), lupus, psoriasis, rheumatoid arthritis, and thyroid disease, may increase an individual's risk of developing vitiligo.
The onset of vitiligo is typically marked by small, white patches that can appear on various parts of the body, including the hands, forearms, feet, and face. Over time, these patches may spread, leading to more extensive depigmentation. The progression of vitiligo is unpredictable, and while some may experience a halt in the spread of the condition, others may see it continue to affect most of the skin surface. In rare cases, individuals may experience repigmentation, where the skin regains its color spontaneously.
Vitiligo is a complex condition that begins with the loss of skin pigmentation, leading to the appearance of white patches on the skin. The process starts when the body's immune system mistakenly targets melanocytes, the cells responsible for producing melanin, the pigment that gives skin its color. This autoimmune response results in the gradual disappearance of melanin in certain areas, causing the characteristic white patches of vitiligo.
The progression of vitiligo is highly individual and can vary significantly from one person to another. It typically starts with small, well-defined white spots, which can remain stable for a long time or spread and enlarge unpredictably. These patches often first appear on sun-exposed areas such as the hands, face, and neck, but they can develop anywhere on the body, including the mucous membranes and the retina.
Vitiligo can be classified into two main types: non-segmental and segmental. Non-segmental vitiligo, the more common form, usually affects both sides of the body symmetrically and can lead to widespread depigmentation. Segmental vitiligo, on the other hand, tends to be more localized and often affects only one side or part of the body.
In non-segmental vitiligo, the depigmentation often starts as a rapid loss of skin color, which may then stop for a while before becoming active again. This start-and-stop pattern can continue throughout the condition. Segmental vitiligo usually progresses more quickly at first, with rapid depigmentation occurring within the first six months to a year. After this initial period, the progression often stabilizes, and new patches may not develop.
The exact triggers that initiate the onset of vitiligo are not fully understood, but they may include genetic factors, oxidative stress, and environmental influences such as sunburns or exposure to certain chemicals. Stressful life events have also been suggested as potential factors that can exacerbate or trigger the condition.
Vitiligo is primarily classified into two main types, each with distinct patterns of depigmentation:
Generalized Vitiligo: This is the most common form of vitiligo and is characterized by macules (smaller patches less than 1 centimeter wide) or larger patches that appear in various places on the body. The patches are usually symmetrical and can spread to cover a significant portion of the body.
Segmental Vitiligo: Unlike generalized vitiligo, segmental vitiligo affects only one side of the body or one area, such as the hands or face. It often begins at an early age and progresses for about a year or two before stabilizing.
In addition to these main types, there are other forms of vitiligo, including:
Mucosal Vitiligo: This type specifically affects mucous membranes, such as those found in the mouth and genitals.
Focal Vitiligo: A less common form where depigmentation is limited to one or a few spots on the body.
Universal Vitiligo: A rare form where most of the skin loses its pigment.
Acrofacial Vitiligo: Depigmentation occurs on the face and extremities, particularly on the fingers and toes.
Vulgaris Vitiligo: Widespread patches that are scattered across the body.
Mixed Vitiligo: A combination of segmental and non-segmental types.
Each type of vitiligo has its pattern of spread and can vary greatly in terms of progression and severity. The treatment and management strategies may differ based on the type of vitiligo, its extent, and the impact it has on the individual.
Vitiligo is a condition that manifests through distinct symptoms, primarily involving changes in skin pigmentation.
The most noticeable symptom is the appearance of white patches on the skin, which occur due to the loss of melanocytes, the cells responsible for producing melanin, the pigment that gives skin its color. These patches are typically well-demarcated and can vary in size, often starting small and expanding over time. They tend to appear symmetrically on both sides of the body, particularly on sun-exposed areas like the hands, face, and neck but can develop anywhere on the skin.
Another common symptom is the premature whitening or graying of the hair on the scalp, eyebrows, eyelashes, or beard. This can occur even in individuals who are relatively young and is a clear indicator of the condition. Vitiligo may also lead to a change in color inside the mouth and nose, affecting the mucous membranes. In some cases, individuals with vitiligo experience a loss of pigment in the retina of the eye, which can be detected during an eye examination.
The progression of vitiligo is unpredictable, and the rate at which the white patches spread or enlarge can vary greatly among individuals. Some may find that the patches remain stable for a long time, while others may witness a rapid expansion. It's also possible for the skin to regain its pigment spontaneously, although this is less common.
Vitiligo can also affect the hair, causing it to turn white or prematurely gray. This includes not only scalp hair but also facial hair and body hair³. The depigmented patches of skin are particularly sensitive to sunlight and can sunburn easily, which underscores the importance of sun protection for those with the condition.
It's important to note that while vitiligo is primarily a cosmetic issue, it can have significant psychological and emotional impacts. The visibility of the symptoms can lead to feelings of self-consciousness and social stigma, making it more than just a physical condition.
Diagnosing vitiligo involves a comprehensive approach that includes a detailed medical history, physical examination, and various tests. Initially, a healthcare provider will inquire about the patient's family history and any autoimmune conditions, as vitiligo is often associated with autoimmune disorders like thyroid disease, diabetes, and lupus.
The physical examination focuses on identifying the characteristic white patches of skin that lack pigment. These patches are usually well-defined and can appear anywhere on the body, but are most commonly found on the hands, face, and areas around body openings.
A Wood's lamp, which emits ultraviolet light, is often used during the examination. This lamp helps to highlight the depigmented areas more clearly, making it easier to distinguish vitiligo from other skin conditions. In some cases, a skin biopsy may be performed to confirm the diagnosis. This involves taking a small sample of the affected skin and examining it under a microscope to check for the absence of melanocytes, the cells responsible for producing skin pigment.
Blood tests are also a crucial part of the diagnostic process. These tests can help identify any underlying autoimmune conditions that might be contributing to the development of vitiligo. For instance, tests for thyroid function, blood glucose levels, and a complete blood count (CBC) can provide valuable insights. Additionally, an antinuclear antibody (ANA) test may be conducted to detect autoimmune activity.
The diagnosis of vitiligo is not solely based on physical findings and tests. The psychological impact of the condition is also considered, as vitiligo can significantly affect a person's self-esteem and quality of life. Healthcare providers often discuss the emotional and social aspects of living with vitiligo with their patients, offering support and resources to help them cope.
Once diagnosed, the treatment plan for vitiligo can vary depending on the extent and location of the depigmented areas, as well as the patient's preferences and overall health. While there is no cure for vitiligo, treatments aim to restore skin color and improve the appearance of the affected areas. Options include topical corticosteroids, calcineurin inhibitors, and light-based therapies such as narrowband ultraviolet B (UVB) phototherapy. In some cases, surgical procedures like skin grafting or melanocyte transplants may be considered.
Vitiligo treatment aims to restore color to the white patches of skin and is tailored to each individual's condition. While no drug can stop the loss of pigment cells entirely, several approaches can help manage the symptoms and improve appearance.
Medications: Topical treatments, such as corticosteroids and calcineurin inhibitors (e.g., tacrolimus or pimecrolimus), are often prescribed to promote repigmentation, especially in the early stages of vitiligo or for small areas of depigmentation. These medications can be effective but may take several months to show results and come with potential side effects like skin thinning or streaks.
Light Therapy: Phototherapy with narrow-band ultraviolet B (UVB) is a common treatment that can stop or slow the progression of active vitiligo. It may be more effective when used in combination with topical treatments. The therapy requires frequent sessions over several months to achieve noticeable changes.
Surgical Procedures: For stable cases of vitiligo where medical treatments haven't been effective, surgical options like skin grafting, blister grafting, or tattooing may be considered. These procedures involve transferring pigmented skin to depigmented areas or implanting pigment into the skin.
Depigmentation: In cases where vitiligo covers a significant portion of the body, depigmentation of the remaining pigmented skin might be an option. This treatment creates a more uniform skin tone by lightening the unaffected skin to match the depigmented areas. However, it is permanent and can take over a year to complete.
Supportive Therapies: Alongside these treatments, supportive therapies such as counseling and joining support groups can be beneficial for dealing with the psychological impact of vitiligo. Protecting the skin from the sun and using cosmetics to camouflage the white patches are also recommended as part of self-care.
It's important to note that the response to treatment can vary widely among individuals, and it may take time to see results. Some treatments may not prevent new patches from forming, and the effectiveness can differ from one part of the body to another. A dermatologist can help determine the most appropriate treatment plan based on the type, extent, and impact of vitiligo on the individual.
Equipped hospitals and advanced specialized centers with experienced doctors and specialists are available in all medical treatment areas in Iran. Also, good hotels and entertainment centers have made Iran an appropriate choice for patients who are suffering from Vitiligo disease. Royan Hospital in Tehran is one of the best centers to treat vitiligo in Iran.
The cost of vitiligo treatment in Iran varies depending on the type and extent of treatment required. Vitiligo is an autoimmune condition characterized by the loss of skin pigmentation, and Iran has been at the forefront of developing innovative treatments for this condition.
One of the most promising treatments available in Iran is the use of Advanced Therapy Medicinal Products (ATMPs), which include cell-based therapies. The cost-effectiveness of ATMPs is a significant consideration. While these treatments can be expensive upfront, they may prove to be cost-effective in the long term due to their potential to provide a more permanent solution to vitiligo. However, the affordability of such treatments can be a challenge for some patients.
In addition to ATMPs, other treatments for vitiligo in Iran include phototherapy, topical corticosteroids, calcineurin inhibitors, and molecular targeted therapies. The cost of these treatments can range from relatively inexpensive for topical agents to more costly for advanced therapies like phototherapy sessions or molecular-targeted drugs.
The cost of vitiligo treatment in Iran is around 500 USD. It's important to note that the prices for vitiligo treatments in Iran are generally lower compared to Western countries, making Iran a favorable destination for medical tourism. Patients from abroad often seek treatment in Iran not only for cost savings but also for the expertise and advanced technologies available.

It seems those with a family history of the disorder or who have certain autoimmune diseases are more likely to get vitiligo. These diseases include: Addison's disease / Pernicious anemia / Psoriasis / Rheumatoid arthritis / Systemic lupus erythematosus / Thyroid disease / Type 1 diabetes
Vitiligo occurs when there’s a lack of pigment called melanin in the skin. Your skin cells (melanocytes) produce melanin, which gives your skin its color. In vitiligo, there are not enough working melanocytes to produce enough melanin in your skin.
Vitiligo does not pose a serious threat to one's health, but it can result in physical complications, such as eye issues, hearing problems, and sunburn. Those with vitiligo usually tend to have another autoimmune disease (like thyroid disorders and some types of anemia).
There is no cure for vitiligo. The treatment is done with the goal of creating a uniform skin tone by either restoring color or eliminating the remaining color. Common treatments include camouflage therapy, repigmentation therapy, light therapy and surgery.
