Café-au-lait spots are light to dark brown pigmented birthmarks that commonly appear on a newborn's skin. Spots can change in size and number over time. More than six café-au-lait spots can be a sign of an underlying genetic condition like neurofibromatosis type 1 (NF1).

Does café-au-lait spots mean neurofibromatosis?

Although these colored spots on the skin can be harmless, having six or more café au lait spots with freckles under the arm or around the groin could indicate an underlying genetic problem called neurofibromatosis type 1. This is a disorder that can affect the skin, nerves, and eyes.

Can you have 6 café-au-lait spots without neurofibromatosis?

Indeed, anyone can have 1 or 2 cafe-au-lait spots without having neurofibromatosis. The only significance to the cafe-au-lait spot is that it suggests the possibility that a person might have NF1. People with NF1 usually have many cafe-au-lait spots, sometimes hundreds, and almost always more than 6.

Should I worry about café-au-lait spots?

Café au lait spots are usually harmless and don't cause any uncomfortable symptoms or complications. But you shouldn't ignore these spots, especially if you have more than a handful on your body. This could indicate an underlying genetic disorder.

Can multiple café-au-lait spots be normal?

Approximately 10% of the general population has one or two café-au-lait spots. However, having more than 5 café-au-lait spots (referred to as multiple CALS) is rare.

Ask Kate! Do my son's café au lait spots mean he has NF1?

Do café-au-lait spots always mean NF1?

The most common symptom of NF1 is the appearance of painless, coffee-coloured patches on the skin, called café au lait spots. However, not everyone with café au lait spots has NF1. The spots can be present at birth or develop by the time a child is 3 years old.

What do neurofibromas look like at first?

Typically, people with NF1 start to see neurofibromas appear during their teens. The neurofibromas grow slowly and may look like a pimple at first. You won't wake up one morning, or next year, and be covered with neurofibromas. They develop gradually over a period of many years.

How many café-au-lait spots are concerning?

Cafe au lait spots usually appear singly. More spots can occur in children with a genetic condition called neurofibromatosis or other conditions. If your child has six or more cafe au lait spots, ask your doctor whether your child needs a medical examination.

When is NF1 usually diagnosed?

Neurofibromatosis 1 (NF1) is usually diagnosed during childhood. Signs are often noticeable at birth or shortly afterward and almost always by age 10. Signs and symptoms are often mild to moderate, but can vary in severity.

Can you have NF1 with no symptoms?

What Are the Signs & Symptoms of Neurofibromatosis Type 1? Most newborns with neurofibromatosis type 1 have no symptoms, but some have curved lower leg bones. By their first birthday, most children with NF1 have several skin spots, called café-au-lait ("coffee with milk") spots because of their color.

Can you have café-au-lait spots and not have NF1?

Can you have café-au-lait spots without having neurofibromatosis? Yes. It is very common for people to have a few café-au-lait spots on their bodies without having an underlying condition like neurofibromatosis type 1 (NF1).

How do I know if my baby has neurofibromatosis?

Light brown spots on the skin called café-au-lait spots. These are the most common signs of NF, and they often appear at birth or in the first years of life. They're harmless, but if your child has more than six, she probably has NF1. Freckles in the armpits or groin area also are signs of NF1.

What do café-au-lait spots indicate?

Café au lait spots are caused by an increase in melanin content, often with the presence of giant melanosomes. A significant increase in melanocyte density is noted in the café au lait macules of patients with NF1 compared with patients who have isolated café au lait macules without NF1 involvement.

How do you test for neurofibromatosis?

Imaging tests.

X-rays, CT scans or MRIs can help identify bone abnormalities, tumors in the brain or spinal cord, and very small tumors. An MRI might be used to diagnose optic gliomas. Imaging tests are also often used to monitor NF2 and schwannomatosis.

Can a blood test detect neurofibromatosis?

A blood test is available for genetic testing to see whether a mutation in the neurofibromatosis type 1 gene is present. A diagnosis of neurofibromatosis type 1 is still possible in people who don't have an identifiable mutation. Testing can now also be performed for SPRED1.

Who is most likely to get neurofibromatosis?

The only true risk factor for developing neurofibromatosis is having a parent who also has the condition. In nearly half of all cases of type 1 and type 2 neurofibromatosis, and in around 15 percent of schwannomatosis cases, the condition is passed down from parent to child.

Can a dermatologist diagnose NF1?

NF1 is also the most common cancer predisposition syndrome. The diagnosis is often made by dermatologists who also operate on cutaneous neurofibroma tumours.

Can you have a neurofibroma without having neurofibromatosis?

Solitary neurofibromas can also occur in people who don't have NF. These are called sporadic neurofibromas. Their cause is not known, although researchers are exploring the role of trauma. Most sporadic neurofibromas don't cause pain and can be managed without surgery or medication.

Can you live a normal life with neurofibromatosis?

If there are no complications, the life expectancy of people with NF is almost normal. With the right education, people with NF can live a normal life. Although mental impairment is generally mild, NF1 is a known cause of attention deficit hyperactivity disorder. Learning disabilities are a common problem.

What can be mistaken for neurofibromatosis?

Legius syndrome also is called a neurofibromatosis 1-like syndrome because its symptoms are similar to NF1. Individuals with Legius syndrome have skin problems including brown birthmarks, called cafe-au-lait spots, and freckling, as well as mild learning problems and a larger head.

At what age do café-au-lait spots appear?

I find that six or more café-au-lait spots are usually visible by around 2 years of age, and new spots do not usually appear after that time, though spots tend to tan upon sun exposure, so may become more distinct with time.

When do freckles appear in NF1?

The freckles usually start to develop around the age of three and become more obvious as the child grows. The unusual areas of freckling have, until very recently, been considered to be characteristic of just NF1. However they are also present in a related condition called Legius syndrome (discussed below).

Does NF1 always get worse with age?

Typically, adults with NF1 will develop more neurofibromas over time. They may grow for a period of time and then stop growing. In addition, they may change in shape or color as they grow. Sometimes, they can also be associated with itching or slight discomfort when bumped.

Is NF1 considered a disability?

Although neurofibromatosis is a serious condition, the Social Security Administration (SSA) does not specifically list the disorder as a disability. But, the symptoms that accompany the condition can be reviewed for benefits.

How do you get rid of NF1 bumps?

There is no known treatment or cure for neurofibromatosis or schwannomatosis. Medication can be prescribed to help with pain. In some cases, growths may be removed surgically or reduced with radiation therapy.
