Have you noticed small red and blue bumps on your skin? Let's talk about angiokeratoma!

Have you ever noticed small bumps suddenly appearing on your skin, which are red, blue, or purple in color? Sometimes you might feel a little scared thinking about these, right? So today we are going to talk about an important topic that you need to be aware of. We call this condition angiokeratoma. Let's see what it is, why it forms, and what else it can do.

Let's simply look at what angiokeratoma is.

Simply put, angiokeratoma is a type of small, hard lump that forms on the surface of your skin. These are caused by the tiny blood vessels near the surface of your skin, called capillaries, becoming enlarged or bursting. This causes the top layer of your skin to thicken. This causes these lumps to appear as red, blue, purple, and sometimes black bumps under the skin.

But the most important thing to tell you here is that these lumps called angiokeratomas are noncancerous/benign tumors . That means they are not cancer, so don't be unnecessarily afraid.

The meaning of this name, in Greek:

• Angio means blood vessels.
• Kera means something solid, like a horn.
• Toma means a tumor.

So with these words comes a little idea about the situation, right?

What are these capillaries?

Now you might be wondering what these capillaries are. Capillaries are the smallest blood vessels in our circulatory system. They are so small, they are like the tip of a pen. We can't see them with our naked eyes except through a microscope.

Just think, there are about 10 billion capillaries like this in our bodies! These are the ones that connect our main blood vessels (arteries) and veins to each other. By connecting them, these tiny capillaries help deliver oxygen and nutrients from the blood to cells throughout our bodies.

Are there types of angiokeratoma?

Yes, there are several main types of angiokeratoma. These affect the middle layer of our skin (we call it the dermis) and the top layer (the epidermis). Let's take a look at what those types are:

Angiokeratoma of Fordyce

This type is most commonly found in the scrotum or penis of men . That is, in the male reproductive system. However, it can also be seen rarely in the vulva of women. Some people may develop not just one or two of these lumps, but hundreds of them.

Angiokeratoma of Fordyce most often affects people over the age of 50. Similar lesions (called angiomas) can sometimes occur in pregnant women or those using hormonal birth control.

Angiokeratoma of Mibelli

This type is most common in young girls . These skin lesions usually appear in the folds of the skin between the fingers (on the hands and feet). They can also appear on the knees, elbows, and breasts. These types of bumps are more likely to bleed .

Angiokeratoma circumscriptum

This is when a baby is born with flat, discolored spots that look like sores . Over time, these spots can turn into raised, red, scaly patches of skin. These can also bleed. These bumps can be smaller than half an inch. But very rarely, they can cover up to a quarter of the body.

These lumps are most often found on one side of the buttocks or thighs. Some children may also develop them on the neck, trunk, testicles, or tongue. This type is very rare , and it is the only type that is more common in girls.

Angiokeratoma corporis diffusum

This type occurs in people with conditions such as lysosomal storage diseases . For example, Fabry disease. These are inherited metabolic diseases. These diseases prevent the body from breaking down certain waste products properly.

These types of skin lesions are usually seen in the genital area, the abdomen, and the area we call the "pants area" from the hips to the knees. They can occur in childhood, adolescence, or even adulthood.

How common is this condition? What are the causes?

Angiokeratoma is actually a relatively rare condition . In the United States, for example, it affects approximately 0.16% of people, or less than 2 in 1,000 people. About 14% of all angiokeratomas are Fordyce's angiokeratomas (the type that occurs on the testicles). This is also most common in white men.

Now let's look at why these angiokeratomas form .

These occur when the tissues that support the capillary walls lose their elasticity (flexibility) . This can be caused by several factors:

• Maybe this is a genetic thing .
• It may be due to certain abnormalities in the blood vessels (vascular malformations).
• It may be caused by prolonged pressure on the blood vessels.
• Or, it could be a long-term , minor itch or scratch on the skin (chronic irritation) .

When this happens, those capillaries become a little hard, swollen, and sometimes they can burst. You may have seen some people with blue veins on their legs, which we call ``spider veins``. This is the same thing. But in an angiokeratoma, what happens is that the enlarged capillary pushes into the skin, forming a raised, discolored bump, which we call a ``papule``.

Furthermore, conditions such as varicose veins in the testicles (varicoceles) or inguinal hernias can put pressure on the capillaries. This can lead to angiokeratoma of the testicles. Similarly, the pressure during pregnancy can cause angiokeratoma of the vulva.

Sometimes, a single angiokeratoma lump may develop at a specific location on the body , years later .

What are the symptoms of angiokeratoma?

Angiokeratomas can look a bit like warts . They can appear anywhere on the body. These bumps start out red, then turn black or purple over time, and the skin over them thickens. However, they may not be as noticeable to people with darker skin.

If you press on one of these bumps with your finger, it will not fade (turn white). You may have just one bump (a solitary angiokeratoma), or you may have as many as 100 bumps.

The following are the common symptoms of angiokeratomas:

• It has a dome-shaped shape .
• Firm or hard to the touch.
• Red, blue, purple or black .
• Usually smaller than a quarter of an inch (5 millimeters) `(Smaller than a quarter of an inch (5 millimeters))`.
• Rough on the surface, with a pebble-like or scaly texture and appearance .

Who is more likely to develop these? (Risk factors)

Anyone can develop angiokeratomas, but some types are more common in certain age groups and genders.

For example, white men are more likely to develop angiokeratoma of the scrotum (Fordyce). Similarly, people with lysosomal storage disorders are more likely to develop angiokeratoma corporis diffusum.

Can this cause other complications?

Some types of angiokeratomas are more likely to bleed even if bruised . Some people may feel very uncomfortable and irritated by these bumps. Others may experience itching or burning .

The important thing is that blood clots can form in angiokeratomas. But these blood clots are not the same as the dangerous blood clots that block blood flow in our bodies (those that cause strokes and heart attacks). They do not put you at risk of having strokes or heart attacks. However, these blood clots can cause pain.

How do you know for sure that this is an angiokeratoma? (Diagnosis)

To find out exactly what this condition is, you need to see a dermatologist . He is a doctor who diagnoses and treats skin diseases.

Although angiokeratomas are not skin cancer, some of the bumps can look like melanoma, a serious type of skin cancer . Your doctor may use a special instrument called a dermoscope to look at the bumps. They may also take a small piece of skin (a skin biopsy) to make sure it's not cancer.

Is there a treatment for this? Can it be cured?

Angiokeratoma bumps don't just go away . Sometimes they can get bigger and more numerous.

But most of the time, angiokeratomas do not require special treatment . However, if these bumps make you feel embarrassed or self-conscious about your appearance, or if they bleed, itch, or cause other problems, treatment may be necessary.

This treatment is done in your doctor's office. You may be given a local anesthetic to numb your skin. But keep in mind that some angiokeratomas can cause scarring .

Your doctor may choose one of these treatments:

• Cryotherapy: Removal of the tumor using extreme cold.
• Electrosurgery or fulguration: Destroying the tumor by applying heat from electricity.
• Laser surgery (ablation): Removal of the tumor using high-intensity light beams.
• Skin excision: Removal of the damaged capillary along with the skin.

What is the outlook for someone with angiokeratoma?

Angiokeratomas can make some people feel sad or embarrassed about their appearance. These feelings can sometimes lead to depression or anxiety . Treatment can help you deal with these changes in your appearance. Some treatments can even remove the lumps completely.

Although most angiokeratomas do not require treatment, it is important to get an accurate diagnosis to rule out more serious conditions .

What are some things you should ask your doctor?

When you go to see the doctor, it's a good idea to ask these questions:

• Why do I have this angiokeratoma?
• What type of angiokeratoma do I have?
• Do I need treatment?
• What treatment options do I have?
• Should I be concerned about symptoms of complications?

Is this a sexually transmitted disease (STD)? Is it skin cancer?

No, angiokeratoma is not a sexually transmitted disease or infection (STD or STI) . You cannot catch it from someone else. Angiokeratoma lumps that develop on the scrotum or labia can sometimes look like genital warts. That's why your doctor may want to examine a small area of ​​your skin to make a proper diagnosis.

Also, as mentioned earlier, angiokeratoma is not skin cancer . Having this condition does not increase your risk of developing cancer.

It is unlikely that angiokeratomas will recur in the same area after treatment. However, new lumps may develop in other parts of your body.
