Does your baby have coffee-au-lait spots? Let's talk about these Café-au-Lait spots!

Have you ever noticed light brown spots on your little one's skin, or perhaps your own skin, that look like the color of a coffee with milk? Some mothers get a little worried when they see these. But not all spots are dangerous. Today we are going to talk about these so-called Café-au-Lait spots. Let's find out exactly what they are, why they occur, and whether they are dangerous or not.

What are these Café-au-Lait spots?

Simply put, Café-au-Lait spots are a type of pigmented birthmark that occurs on the skin. "Café-au-Lait" is a French word that means "coffee with milk." So, the color of these spots can range from light brown to dark brown, just like coffee with milk. This color looks different from the rest of your skin.

These spots can range in size from a few millimeters to more than 20 centimeters. They are often present on babies' skin at birth or appear during childhood. However, sometimes these spots can develop in adults as well. They are not raised bumps on the skin, but are flush with the skin.

Are there types of these spots?

Yes, these Café-au-Lait spots are mainly divided into two types based on their shape and pattern. These names may sound a bit strange, but there is a reason for them.

1. "Coast of California" type: This is the most common type. Like the coastline on the map of the state of California in the United States, these spots have very clear, smooth edges. There may be a single spot or several spots with clear edges.

2. "Coast of Maine" type: This is a slightly less common type. Like the coast of Maine in the United States, these spots have rough, slightly jagged edges.

The important thing is that if your child has more than six "Coast of California" spots on their skin, it's important to seek medical advice. Because having multiple spots can sometimes be a sign of an underlying condition, such as a genetic condition like Neurofibromatosis type 1 (NF1) . These are conditions that affect the skin and nervous system.

Who gets these spots most often? How common is it?

Café-au-Lait spots can happen to anyone. They are often congenital, meaning they are present at birth. However, they may not be as noticeable on a newborn baby's skin. As they get older, especially after the age of two, they become more noticeable.

Although these spots are more common among people with darker skin tones, they can occur in anyone with any skin color.

Some café-au-lait spots are linked to genetic conditions. This means that if someone in your family has the condition, it may be a hereditary trait. If you are planning to have children, it is important to find out if there is a genetic condition in your family. You can talk to a doctor to learn more about this and ask about genetic testing .

These spots are so common that it is estimated that about 10% of the general population has at least one Café-au-Lait spot.

Also, 95% of people with neurofibromatosis type 1 (NF1) have more than six café-au-lait spots.

Do Café-au-Lait spots affect the baby in any way?

Most of the time, Café-au-Lait spots are just spots. They are non-cancerous (benign), meaning they are not dangerous, and they do not cause any harm to the child's body. So, even if you have one or two of these spots, there is nothing to worry about.

However, as I mentioned earlier, if your child has more than six (06) of these spots on their skin, you should definitely see a pediatrician or dermatologist. As the number of spots increases, it could be a sign of another underlying genetic condition.

How exactly do these spots look?

There are several characteristics that can help you distinguish café-au-lait spots from other birthmarks. Let's take a look at what they are:

• Flat spots: These are not raised like bumps. They are usually found on the trunk, arms, legs, and buttocks.
• A color ranging from light brown to dark brown: like the color of coffee with milk.
• Round or oval shape: Size can range from 2 millimeters (mm) to more than 20 centimeters (cm).
• A smooth or rough edge around the spot: like the "California beach" or "Maine beach" we talked about.
• The size and number of spots may increase with age.
• These spots do not cause pain, itching, or other symptoms.

Why do these Café-au-Lait spots appear? What is the cause?

The main reason for the formation of these spots is the increase in the number of melanocytes, a type of cell that gives color to the skin, in the thin outer layer of our skin, the part called the epidermis. These melanocytes produce the pigment melanin . This melanin gives color to our skin, eyes, and hair, and also protects the skin from sunlight. So, if a large number of these melanocyte cells suddenly accumulate in a certain area, the production of melanin also increases, and the skin color in that area becomes dark brown. That is the Café-au-Lait spot.

However, a clear reason has not yet been found as to why these melanocyte cells often accumulate in such large numbers in one place.

However, neurofibromatosis type 1 (NF1)Café-au-Lait spots are caused by a mutation in a gene called the NF1 gene . The NF1 gene controls how quickly cells grow. So when this gene is mutated, melanocyte cells grow uncontrollably and produce too much melanin in the skin.

Sometimes, the NF1 gene mutation can occur randomly, without anyone else in the family having it. Other times, if one of the parents has the mutated NF1 gene, the child can inherit the condition. This is called autosomal dominant inheritance . However, unlike other autosomal dominant conditions, for NF1 to fully develop, a mutation in the second copy of the NF1 gene must also occur during a person's lifetime. This is a bit complicated, so it's best to ask a doctor for more information.

How does a doctor recognize these spots?

After your baby is born, the doctor will do a full check-up on your baby, right? At that time, the doctor will note any birthmarks on your baby's skin, including Café-au-Lait spots. He or she will also advise you to check how many of these spots your baby has as he or she grows.

These spots may not be completely visible on a newborn baby's skin, but by the time the baby is about two years old, or after exposure to the sun, these spots become more visible.

If there are more than six spots, could it be a sign of another disease?

Yes, that's something we should be especially concerned about. Having more than six (06) Café-au-Lait spots can be a sign of some underlying genetic conditions. Some of these conditions include:

• Neurofibromatosis type 1 (NF1)
• McCune-Albright syndrome
• Noonan syndrome
• Watson syndrome

So, if you notice more than six Café-au-Lait spots on your child's skin, don't waste any time and see your child's doctor right away. He or she can examine the spots and refer you for further testing if necessary.

Is there a treatment for these Café-au-Lait spots?

Café-au-Lait spots are non-cancerous (benign), meaning they are harmless, so they usually do not require treatment. They do not cause any symptoms.

However, some people may want to remove these spots for cosmetic reasons, that is, to look better. In that case, you can talk to your doctor about laser treatment . However, there are some risks when removing spots with laser treatment. For example, the skin color may become darker in the treated area (hyperpigmentation)., scars may form, the color of the spot may not disappear completely, or the spot may reappear after removal.

Is there a way to reduce the occurrence of these spots on babies?

Actually, there is no way to prevent Café-au-Lait spots from forming, because we cannot prevent birthmarks from forming.

However, if someone in your family has a genetic condition like neurofibromatosis type 1 (NF1) , talking to a doctor about genetic testing before you plan to get pregnant can help you understand your risk of having a child with that condition.

If my baby has these spots, what should I expect?

Café-au-Lait spots are present from birth. They can remain throughout a child's life. The size and shape of these spots may change slightly over time. Also, these spots may become more visible when exposed to sunlight.

The most important thing is to seek medical advice if you notice more than six of these spots on your child's skin to see if it is a sign of another underlying medical condition.

When do you need to see a doctor?

If you notice any changes in your child's Café-au-Lait spots, for example , if the spots become swollen, raised, feel lumpy when touched, or if the size or number of spots suddenly increases, see a doctor immediately.

It is normal to have a few café-au-lait spots. However, having more than six spots may be a sign of an underlying medical condition. Here are some additional symptoms associated with common underlying conditions that cause café-au-lait spots:

• Speech and language problems.
• Non-cancerous lumps under the skin (neurofibromas) .
• Freckles under the armpits.
• High blood pressure (hypertension) .
• Bone growth problems, for example , scoliosis .
• Attention-deficit/hyperactivity disorder (ADHD) .

If your child has other symptoms like these along with a lot of Café-au-Lait spots, inform the doctor about that as well.

What are the important questions to ask the doctor?

When you go to see a doctor, you can ask questions like these:

• Are my child's café-au-lait spots a sign of a genetic condition?
• Can I get a genetic test to assess my risk of having a child with a genetic condition?
• What should I do if I see more than six Café-au-Lait spots on my child's skin?

Can Café-au-Lait spots suddenly appear even after adulthood?

Yes, it can happen. Although café-au-lait spots are often present on the skin of newborns, it is also common for these spots to develop on someone’s skin later in life. It is normal for someone to have a few café-au-lait spots. However, if you have more than six spots, it could be a sign of an underlying medical condition. So, regardless of your age, if you notice more than six café-au-lait spots on your skin, see a doctor to have them checked.

Can these spots be present without neurofibromatosis?

Yes, absolutely. It is very common for people to have several café-au-lait spots on their bodies without an underlying condition, such as neurofibromatosis type 1 (NF1) . People with NF1 usually have more than six café-au-lait spots, and they also exhibit other symptoms consistent with the diagnosis.

Are these spots like a skin rash?

No. Although these spots may look like a rash, Café-au-Lait spots are not caused by an allergic reaction. A rash is usually pink or red, right? But Café-au-Lait spots range in color from light brown to dark brown. Also, while a rash can cause symptoms like itching, Café-au-Lait spots do not cause any itching or other discomfort.

Finally, things to remember

Café-au-Lait spots are a type of birthmark that can appear on your child's skin, and are often harmless. Although they are not dangerous, it is important to keep track of how many of these spots your child has. More than six spots could be a sign of an underlying medical condition. If you notice any changes in your child's birthmarks, seek medical advice immediately. Don't panic, awareness is key!
