Dilated Pore of Winer: Picture, Causes, Treatment and Prevention

by Dr. Joe Morales

A pore that appears like a large blackhead may be a dilated pore of Winer. It is a noncancerous tumor of sweat glands in your skin or hair follicles.

It is a single enlarged pore that is blocked by a dark plug. It generally occurs on one’s head or neck, but it may also appear on their trunk.

It was first described by Dr. Louis H. Winer, this is where it gent’s the name black pre on Winer. It took place in 1954.

If you wish to learn more about dilated pore of Winer with its causes, treatments, and more. Here’s all you need to know.

Dilated Pore Of Winer

It is sometimes a large lesion that appears like a circle with an open and large area of a dark substance. This dark substance is in the pre in keratin, a protein in the skin so tough that it makes our hair and fingernails.

The dilated pore of Winer is normally much larger than a visible blackhead, but some may seem very close in appearance, which makes it difficult to figure out. Principal symptoms of a dilated pore of Winer are:

  • the appearance of a single and enlarged pore.
  • black-appearing “plug” present in the middle of the enlarged pore
  • healthy and normal-appearing skin in the surrounding region.

These lesions usually appear on the head and neck, often on the face. However, some people may notice a pore of Winer on their trunk, particularly the back.

Now that you know what dilated pore of Winer appears like. Let’s see what are its causes so you can avoid getting one.

Causes of Dilated Pore Of Winer

Doctors don’t exactly know what provokes a dilated pore of Winer. While there have been a few theories over past years, the most popular and recent one is that wound or scar tissue begins to build around a cyst inside the pore, forming an enlarged pore.

Doctors have also recognized some dangerous and risk factors for this particular ailment: People who are middle-aged or older often are at more risk of developing it, as well as those people with a prior history of severe acne are at risk.

It’s also considered to be more common in white males who have become older than 40 in getting now.

In very rare situations, a dilated pore of Winer can appear somewhat similar to a basal cell carcinoma,  which is a form or type of skin cancer. For this purpose, a doctor might have to perform a biopsy to make sure that the pore of Winer is not due to another underlying skin disease.

Other skin Conditions That It May Resemble

You have seen all the possible causes of Dilated pore of Winer and know by now how it appears. It may sometimes look like some other skin conditions and one might get confused between these conditions and the pore of Winer. These include:

  1. Pilar cyst.
  2. Sebaceous trichofolliculoma.
  3. Hair cortex comedo
  4. Epidermal inclusion cyst.

Another skin ailment known as a pilar sheath acanthoma appears a lot similar to a dilated pore of Winer. Many times it’s difficult to tell the contrast between the two conditions. However, pilar sheath acanthoma normally appears on an individual’s upper lip. They might also be less well-formed and symmetrical in nature when we compare to a dilated pore of Winer.

To make a judgment or diagnosis of the condition, a dermatologist will check the site carefully. They may also take a biopsy test to help verify their diagnosis.

The solution is to not pick at the sore or acne before a doctor takes a look at it. This could aggravate or irritate the pore, causing it harder to diagnose and thus harder to treat.

Treatment of Dilated Pore Of Winer

when we look from a health viewpoint, you do not require an enlarged pore of Winer. This pore is not as dangerous as you think it is to your health. It should not even cause pain most of the time. However, it could be a prominent and cosmetic concern over time.

There are not many at-home medical operations or remedies you can follow, such as applying topical applications to treat a dilated pore of Winer. But talking to your doctor to get the pore removed may be a great idea if it troubles you.

The doctors may use the following to remove the dilated pores from your skin:

Comedone Extractors

Some skincare professionals and doctors may try to eliminate the dilated pore of Winer with the help of a Comedone extractor. This is normally a plastic or metal tool having a small hole in the middle. The device or tool puts force on the skin that helps release the keratin plug from the skin.

However, know that this proposal of removing a pore of Winer would not make the pore go away completely. Skin cells will possibly mount a backup and form the dilated pore of Winer appear again. So you cannot take this as a permanent solution.

Also, it is highly important that you do not try or perform this at home. Handling the pore too much may lead to swelling inflammation and infection.

Surgery To Remove A Dilated Pore Of Winer

A dermatologist might also otherwise handle the dilated pore of Winer by surgically removing the area using a biopsy. This is customarily an in-office method for removing.

According to a report from the year 2019, this elimination approach normally “cures” or treats the pore fully without any chances of reappearing.

While it may appear like a great idea to you as it involves the pore going away completely, there are some side effects due to the involvement of surgery. These complications are something you must know before opting for a surgical approach- Scarring, bleeding, and infection.

However, by practicing proper anti-infection and aseptic techniques, one can help reduce contamination and infection risks. These include caring for the wound after the procedure gets over, such as having the skin clean and dry.

If you notice any of the symptoms like redness, swelling, or warmth to touch the site of infection, you must call your healthcare provider immediately.

Other Approaches to treatment

There are few procedures that doctors have used to treat pore of Winer but couldn’t. However, some of the treatment techniques used did provide the patients with temporary relief for the pores. These include:


One way the doctors can readily eliminate warts is by using the freezing technique in which the warts are frozen. This technique is called cryotherapy. During therapy, a doctor immediately uses liquid nitrogen, a really cold material, to wart on your skin. This makes warts freeze off.

Most warts you know that are not located in the genital area can be operated on using this procedure of cryotherapy. Research advises that cryotherapy may be especially effective in operating the warts of your hand, even when equaled to traditional creams applied topically. Cryotherapy might also be remedial in healing plantar warts present on the feet.


Dermabrasion is another exfoliating procedure that uses a rotating tool to eliminate the outer layers of your skin, normally on the face. This practice is famous for people who prefer to update the exterior of their skin. Some of the ailments it can treat are fine lines, damage from the sun, acne, and scars, and uneven skin texture.

Dermabrasion usually occurs in a dermatologist’s office. Throughout the procedure, a trained expert will numb your epidermis with anesthesia before lifting the outermost folds of the skin. This is an outpatient method, meaning that you may go home to improve and heal following the treatment.

There are certain over-the-counter tools that mimic the exfoliating and cleansing procedures of professional practices. This normally takes a lengthened time period to produce the desired skin-smoothing results of professional dermabrasion and normally does not deliver complete effects as expected. 


Electrocauterization is a conventional surgical procedure that is used regularly. A certified surgeon or doctor performs this procedure by using electricity to heat skin tissue in order to prevent infection, remove any abnormally growing tissue, and prevent bleeding during surgery or after the surgery takes place. Not only it prevents bleeding, but it also helps stop the bleeding after an injury. 

This treatment has a number of uses to start with. It is used during surgical procedures or cosmetic procedures. It can also be used by surgeons in wart removal, nasal treatment, tumor removal, etc.

This procedure does not require you to do any special preparation. In the case there is excessive bleeding, the doctor may ask and take a blood sample to test for conditions like clotting disorder and anemia. Frequent nosebleeds are a good example to understand what excessive bleeding refers to. 

Laser surgery

Laser therapies are again medical treatments that perform the procedure using focused light. Unlike many other light reservoirs or sources, light from laser operation is tuned to particular wavelengths. This will allow the light to be focused on only powerful beams. Laser light is highly strong and can be used to mold diamonds or cut steel.

For medicinal purposes lasers enable surgeons to operate at high levels of accuracy by concentrating on a small area and damaging less of the surrounding tissue. If you go for laser therapy, you might endure less pain, scarring, and swelling than undergoing traditional surgery. However, laser therapy can be highly pricey and need repeated treatments.

However, all the treatments and surgical procedures mentioned above do not usually cure the condition of dilation pores. This is because they mostly cannot penetrate intensely and deeply enough inside the skin to remove enough of the substances and the dilation pore of Winer itself. They may work temporarily to reduce its expression on your skin, but there are chances of the pore likely coming back.

Prevention of dilated pore of Winer 

Since there isn’t any recognized cause for the skin condition, there is not much one can do to prevent dilated pores of Winer.

People who have had a past experience of acne are more likely to undergo a dilated pore of Winer. However, the skin ailment is not due to what you did or didn’t do in terms of maintaining healthy skin or taking care of your skin. 

If you’re highly concerned about getting a dilated pore of Winer, you must visit a dermatologist or talk to your doctor about the treatments involved. 

The Bottom Line 

Know that a dilated pore of Winer is not a dangerous skin condition that needs immediate treatment like others. For some people, the appearance of a dilated pore on their skin might be a cosmetic concern that lowers their self-confidence. If it is so, you can get it removed with the doctor’s help. Expert dermatology will be able to diagnose and treat the condition surgically. 

If you have any lesion that you sense to be a dilated pore, visit your doctor and know more about possible treatments. Make sure you are not doing anything to remove the dilated pore by yourself using at-home remedies. They may worsen the pore. 

This was everything about dilated pores of Winer and the treatments involved.
