Do I have NF1?

Symptoms of neurofibromatosis type 1

birthmarks known as café au lait spots, which are light or dark brown patches that can be anywhere on the body. soft, non-cancerous tumours on or under the skin (neurofibromas) clusters of freckles in unusual places – such as the armpits, groin and under the breast.

Can you have NF1 and not know it?

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.

How do I know if I have neurofibromatosis?

To diagnose NF1, a doctor looks for some of the following: Six or more flat, light brown spots on the skin (“café-au-lait” spots), which are the most common feature of NF1. These multiple birthmarks measure more than 5 millimeters in diameter in children or more than 15 millimeters across in adolescents and adults.

Does everyone with NF1 get tumors?

An estimated 3% to 5% of people who have NF1 develop cancerous tumors. These usually arise from neurofibromas under the skin or from plexiform neurofibromas.

Does NF1 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.

Can you have NF1 without café-au-lait spots?

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). People diagnosed with NF1 usually have more than six café-au-lait spots on their bodies along with additional symptoms related to their diagnosis.

Can café-au-lait spots be normal?

Café au lait spots are harmless and normal, with some people having anywhere from one to three spots. But sometimes, these spots can indicate an underlying genetic problem.

Do neurofibromas look like pimples?

A neurofibroma may look like a pimple at first and may grow gradually in size. A person with NF1 may continue to gradually develop new neurofibromas over the years throughout adulthood.

Can NF1 cause leg pain?

Troublesome symptoms of NF1: When to call the doctor

numbness, tingling or weakness in an arm or leg. changes in neurofibromas, such as persistent and continuous pain, rapid increases in size or hardening.

What does NF1 look like?

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.

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.

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.

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).

How can you test and confirm NF1?

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.

How painful is NF1?

One in 4 persons with NF1 experience chronic pain that can persist for months to years and characterized as a painful peripheral sensory neuropathy [64]. While ~70% of children and adults with NF1 use prescription pain medications [22], pain is often overlooked [22; 111].

Does NF1 cause back pain?

Spinal neurofibromas

Occasionally, adults with NF1 will experience back pain, numbness in an arm or leg and minor weakness. People who develop these symptoms should consult a physician who is an expert in NF1.

When do café-au-lait spots appear?

Typically, café au lait spots are present at birth, although they may be difficult to appreciate. A Wood lamp may improve the ability to visualize these faint spots. By the time the child is aged 2-3 years, café au lait macules are clearly visible.

Are neurofibromas hard or soft?

A neurofibroma is a type of nerve tumor that forms soft bumps on or under the skin. A neurofibroma can develop within a major or minor nerve anywhere in the body. This common type of benign nerve tumor tends to form more centrally within the nerve.

How do I know if my child has NF1?

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.

Can café-au-lait spots get bigger?

Café-au-lait macules are harmless light to dark brown, oval, well-defined spots. They are normally present from birth and can increase in number and size over time.

What is the minimum number of café-au-lait spots that should be of concern?

It is not unusual for a healthy child to have a few café-au-lait spots, and it is not recommended to provide an evaluation for NF1 if the spots are fewer than six in number. These spots also should be clear and distinct – finding very faint or small skin spots does not count towards the six spots needed for diagnosis.

How many café-au-lait spots are normal?

The size of café au lait spots can also vary. Spots can be as small as a half centimeter. The spots are usually present at birth but may develop later in life. Café au lait spots are harmless and normal, with some people having anywhere from one to three spots.

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.

How do you rule out NF1?

Your child's doctor will look for signs of NF1 in your child's skin, eyes, bones or brain. The second method is genetic testing, also called a molecular or DNA diagnosis. Your child will need to give a blood sample. A lab will check the sample for a change (mutation) in the NF1 gene.

Can NF1 tumors be removed?

If cancerous tumors develop with neurofibromatosis—for example, malignant plexiform neurofibromas, which can develop in the arms, legs, or trunk—they can also be surgically removed. For cancerous tumors, surgery may be combined with other treatments for cancer.
