In this series, we share skin health concerns that change every month. We provide clear answers and useful tips for monthly skin diseases that everyone is curious about, with experts from Liwon Dermatology Clinic.

An increasing number of people are experiencing stress due to the lumpy lesions under the eyes that began to become noticeable at some point. Military lesions that appear around the eyes, which are a particularly visible part of the face, are easy to mistake for a simple trouble, as papules similar to migratory acne appear around the eyes.

However, dermatological diseases with similar symptoms include ‘milia’ and ‘ductal tumor’. These similar-looking symptoms may appear similar on the outside, but it is important to distinguish them because the course of the disease and treatment are different. Let’s learn more about the differences between ductal tumors and milia with dermatologist Dr. Lee Mi-hye (Riwon Dermatology Clinic).

Q. What is the cause of milia and ductal tumors?
Milia and ductomas are generally asymptomatic and relatively common benign lesions. It is common on the face, including around the eyes, and has the ability to create lesions that protrude from the skin surface, but there are differences in histological findings and treatment.

Although the cause is not clearly known, milia can occur on both baby and adult skin, and congenital effects or various skin damage are known to be the causes. Milia are lesions filled with keratin in pockets just below the epidermis, which is the relatively surface of the skin. They are observed to the naked eye as small, protruding lumps containing white or yellow lumps.

Hangwandoma is a hereditary disease, so if someone in your family has Hangwandoma, you may develop Hangwandoma hereditarily. Abnormal proliferation of sweat passages is suggested to be the main cause. A duct tumor is a type of benign tumor that occurs when the sweat ducts that secrete sweat proliferate. Because the lesion originates from the sweat gland duct, the lesion is located in the deeper dermal layer compared to milia and is more likely to recur even after treatment.

Q. What are the different treatments for milia and ductal tumors?
Clinical judgment is important depending on the depth, size, and distribution of the lesion. In most cases, milia are removed by direct destruction or extrusion using an erbium or CO2 laser or needle.

Because keratinoma is not a skin disease that heals naturally, it is recommended to receive an accurate diagnosis from a dermatologist before symptoms worsen. Like milia, a method of destroying ductal tumors from the skin surface using an erbium or CO2 laser can be attempted. Since the lesions are located deeper and have unclear boundaries compared to milia, microneedles such as Potenza 1pin or Agnes can be used. If you combine the method of removing lesions while minimizing damage to the skin surface using high-frequency treatment, scarring and recovery time can be reduced compared to existing treatments, so satisfaction is high.

Both milia and ductomas are relatively common benign lesions, and they often occur in combination. Even if they are mixed, the treatment does not change. Milia can be treated with milia, and milia can be treated with ductal tumors.

Q. There are many cases where ductal tumors are mistaken for milia. What are the characteristics that distinguish the two diseases?
Because both ductal tumors and milia are similar in appearance and size and mainly occur under the eyes, it is easy to confuse the two diseases. However, in typical cases, ductal tumors and milia can be distinguished visually.

Tumors grow deeper in the skin, and they mainly occur around the eyes, cheeks, forehead, or philtrum, and have a multiple appearance. It has a color close to the color of skin and is not easily separated from normal tissue when removed.

Milia occur shallowly on the surface of the skin and are white or yellow, ball-shaped keratin sacs that are well bordered with the surrounding skin. It mainly occurs on the face, including around the eyes and cheeks, and is easier to treat than a vascular tumor, but since it is a common disease, it often recurs.

Q. It is said that Hanwanoma is a skin disease that is difficult to treat once it develops. What efforts are needed to prevent recurrence?
Both ductal tumors and milia are relatively common and frequently recur, causing concern to many people. In particular, it is known that ductal tumors are difficult to treat because the lesions are deeper than milia and are not well separated from normal tissues. Prompt treatment can prevent the progression of lesions, and if left untreated, lesions may increase in number, spread, and fuse, making treatment more difficult. Repeat treatment is usually recommended.

※Honey TIP. Milia prevention method※

1. If you have excessive sebum secretion, do not apply oily cosmetics!

2. For prevention, apply moisturizer and sunscreen from time to time.

3. Avoid rubbing your eyes excessively or using high-functional cosmetics for a long time as this can cause irritation.

4. Milia often appear when there is a skin disease, so if you have itching or dermatitis, get treatment right away.

5. If you try to squeeze too much at home, inflammation and scarring may occur. Never squeeze it by hand.
