Definition of neurofibroma - NCI Dictionary of Cancer Terms

can occur anywhere in the body outside of the brain and spinal cord. They can occur on the face (including around the eye), neck, arms, legs, back, chest, abdomen, and internal organs.

What does a plexiform neurofibroma look like?

These tumors look like lumps under the skin. The skin over the lump may feel thicker and appear darker than the skin around it. The lump itself may feel like a bundle of thick cords or knots. Plexiform neurofibromas have a type of cell that releases histamine, a chemical in the body that can cause itching.

What does plexiform mean in medical terms?

: of, relating to, or having the form or characteristics of a plexus.

What does a plexiform feel like?

Plexiform neurofibromas often feel like a bunch of cords or knots beneath the skin and may have a variation in texture or darker pigmentation on top of the skin.

What causes plexiform neurofibroma?

Causes. People who get plexiform neurofibromas are usually born with a rare genetic disease called neurofibromatosis type 1 (NF1), or von Recklinghausen's disease. Around 30% to 50% of people who have NF1 will get one or more throughout their life.

Plexiform Neurofibroma in Neurofibromatosis-1 NF1: 5-Minute Pathology Pearls

Is plexiform neurofibroma a tumor?

A tumor that forms in the tissue that covers and protects the nerves. Plexiform neurofibromas can occur anywhere in the body outside of the brain and spinal cord.

Are plexiform neurofibromas painful?

Abstract. Plexiform neurofibromas (PNs) are common and potentially debilitating complications of neurofibromatosis 1 (NF1). These benign nerve-sheath tumors are associated with significant pain and morbidity because they compress vital structures.

Can you live a normal life with neurofibromatosis?

Children and adults with NF1 can have a variety of symptoms and medical problems which can change across a lifespan. Most people with NF1 have a normal life expectancy. Because many of the other clinical features of NF1 develop as an individual gets older, getting the correct diagnosis may take several years.

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.

At what age is neurofibromatosis usually diagnosed?

Neurofibromatosis 1. 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.

What is the life expectancy of a person 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.

What is the disease that causes lumps all over body?

A Neurosurgeon Explains: Neurofibromatosis

Neurofibromatosis (NF), a type of phakomatosis or syndrome with neurological and cutaneous manifestations, is a rare genetic disorder that typically causes benign tumors of the nerves and growths in other parts of the body, including the skin.

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.

How fast do plexiform neurofibromas grow?

The median rate of growth of the individual tumours expressed as a percentage of the volume measured on the first exam was 2.8% per year, with a range of −35.9% to 3667% per year.

Can neurofibroma turn malignant?

A neurofibroma is usually noncancerous (benign). Rarely, it can become cancerous (malignant).

What happens if neurofibromatosis is left untreated?

These tumors originate from Schwann cells, which protect your nerve cells and neurotransmitters. Spinal cord schwannomas are common in those with NF2. If left untreated, they can cause paralysis.

Does NF1 qualify for 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 serious is NF1?

The symptoms of neurofibromatosis type 1 (NF1) are often mild and cause no serious health problems. But some people will have severe symptoms. The symptoms of NF1 can affect many different areas of the body, but it's unlikely someone will develop all of them.

Is NF1 life threatening?

In most cases, symptoms of NF1 are relatively mild, allowing patients to live normal and productive lives. However, the disorder can also be debilitating and, in some cases, life-threatening. NF1 can lead to problems within various systems, organs and functions of the body including: Skin, bone and eye abnormalities.

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.

What are the 3 types of neurofibromatosis?

Does diet affect neurofibromatosis?

Excessive consumption of saturated fatty acids and lipids was also observed in both male and female patients. Conclusions: In this study, NF1 patients consumed an unhealthy diet that was rich in fats and sodium and lacking in fiber, vitamins, and minerals.

How is plexiform neurofibroma diagnosed?

How are plexiform neurofibromas diagnosed? Although diagnosis of these lesions is usually possible by examination of the child, the full extent of the lesion is best seen by MRI scan. MRI scans may show these lesions to be much more extensive than previously thought.

How does neurofibromatosis affect the brain?

Neurofibromatosis is a genetic disorder that is typically diagnosed in childhood or early adulthood. This disorder can cause tumors to develop in the nervous system, including the brain, spinal cord and nerves. In most cases, these tumors are benign and slow-growing.

Why is neurofibromatosis so painful?

Plexiform neurofibromas are associated with NF1 and can be present at birth, although they can be hard to detect in a young person. Most do not cause any problems, but some plexiform neurofibromas can grow very large, place pressure on nerves and organs, and cause pain and weakness.
