Saetgang Station Dermatology Clinic: Changes to Check for Vitiligo Before the Symptoms Spread (JTBC Documentary Plus Q)

Vitiligo does not always appear as extensive white patches from the beginning.

At first, small patches may appear in specific areas such as the hands or face and remain similar for a long time. At some point, however, existing patches may expand or new patches may appear on other parts of the body.

For this reason, with vitiligo, it is important to check how the skin has recently been changing, just as much as the size of the white patches currently visible.

Vitiligo is a condition in which some areas of the skin turn white as melanocytes, the cells that produce skin color, are lost. Its progression can vary from person to person.

Non-segmental vitiligo can be difficult to predict, as it may progress slowly over several years or suddenly progress rapidly.

Therefore, if you are looking into vitiligo at a Saetgang Station dermatology clinic, it is important to examine not only how many white patches are present but also the size of existing lesions and whether new lesions have appeared.

Today, we will look at the changes that may indicate that vitiligo is spreading and the points to consider before treatment.

If vitiligo is progressing,

What changes may appear?

If existing white patches are expanding or lesions appear in new areas, it is necessary to check for changes in the vitiligo.

Vitiligo does not progress at the same rate in everyone.

It may remain at a similar extent for a long time, but existing patches may change in size or new lesions may develop.

In particular, it is a good idea to check for the following changes.

• The area covered by an existing white patch has expanded

• A patch has appeared in a new area

• Multiple small white patches have appeared in several areas

• The extent of depigmentation around a patch has changed

• A patch has appeared in an area that is frequently injured or rubbed

Vitiligo commonly appears on areas subject to frequent friction, such as the hands, feet, elbows, and knees. Trauma or repeated friction may affect the development or worsening of lesions.

Therefore, when you first notice a lesion, it is a good idea to check not only its current appearance but also whether its size or location has changed over the past several months.

Are all white patches vitiligo?

Not every area of skin that appears white is vitiligo, so an accurate diagnosis comes first.

Therefore, rather than concluding on your own that a white patch is vitiligo, you should check the lesion’s borders and location, as well as when it first appeared.

Another option is to photograph the lesion when you first notice it.

Taking photographs at regular intervals under similar lighting and from a similar distance may help you compare whether an existing patch is expanding or whether changes have appeared in new areas.

Ultimately, what matters is not simply the presence of a white patch, but accurately determining what type of pigment change it represents.

If vitiligo is spreading,

How might treatment differ?

Vitiligo treatment should take into account not only the location and extent of the lesions but also whether the condition is currently progressing.

When considering treatment, it is easy to focus first on restoring pigment to skin that has already turned white.

However, if new lesions have recently continued to appear or existing lesions have been expanding, the current activity of the condition should be assessed first.

The treatment approach is also determined by considering the extent of the lesions and the activity of the condition.

Depending on the condition, topical or oral medication, phototherapy, or an excimer laser may be considered.

In particular, an excimer laser may be used for localized vitiligo affecting a relatively small area.

Even after treatment begins, it is necessary to continue checking whether existing lesions are expanding, whether new patches are appearing, and whether pigment changes are occurring in the treated areas.

Therefore, even after treatment for vitiligo, it is important to consistently monitor changes in the lesions and observe the course of the condition.

Vitiligo appears as white patches on the skin, but its subsequent progression can vary from person to person.

In some cases, the lesions remain a similar size for a long time, while in others, existing lesions expand or patches appear in new locations.

Therefore, if you are looking into vitiligo, it is important to check not only the lesions currently visible but also whether there have recently been changes in their size, number, or location.

In addition, not all white patches are vitiligo. It is necessary to receive an accurate diagnosis first, and if vitiligo is confirmed, determine the treatment approach according to the extent of the lesions and whether the condition is progressing.

Vitiligo Q&A

Q. How can I tell whether vitiligo is spreading?

A. You can check whether existing white patches are increasing in size or whether patches are appearing in new areas. Keeping photographic records of the previous condition can help you compare changes.

Q. Could one small white patch be vitiligo?

A. It is possible, but vitiligo cannot be diagnosed based on a white patch alone. Because other skin conditions may look similar, an accurate diagnosis is necessary.

Q. Can frequently scratching or rubbing the skin also have an effect?

A. In some patients, trauma or repeated friction may affect the development or worsening of vitiligo lesions, so it is advisable to reduce skin irritation.

Q. Does the treatment method change if vitiligo is progressing?

A. Yes. The treatment approach for vitiligo is determined by considering not only the extent and location of the lesions but also the current activity of the condition. Therefore, if new lesions appear or the existing lesions expand rapidly, it is important to assess the current condition first.
