Symptoms of Neurofibromatosis
Neurofibromatosis (NF) is a genetic disorder that affects the nervous system, causing the growth of tumors on nerves throughout the body. There are three types of neurofibromatosis: NF1, NF2, and schwannomatosis. Each type has its own set of symptoms and characteristics.
Neurofibromatosis Type 1 (NF1)
Neurofibromatosis type 1, also known as NF1 or von Recklinghausen disease, is the most common form of neurofibromatosis. It is caused by a mutation in the NF1 gene and affects approximately 1 in 3,000 individuals worldwide. NF1 is characterized by the development of benign tumors called neurofibromas on or under the skin, as well as other symptoms.
The symptoms of NF1 can vary widely from person to person, but some of the most common signs include:
- Café-au-lait spots: These are flat, light brown spots on the skin that are often present at birth or appear in early childhood. They can vary in size and number.
- Neurofibromas: These are benign tumors that grow on or under the skin, as well as on nerves throughout the body. They can range in size from small nodules to larger masses.
- Lisch nodules: These are tiny, harmless tumors that develop on the iris of the eye. They do not typically affect vision.
- Freckling: Freckles in the armpits, groin, or other skin folds may be more numerous in individuals with NF1.
- Learning disabilities: Some individuals with NF1 may experience learning difficulties, such as attention deficit hyperactivity disorder (ADHD), problems with spatial awareness, or difficulties with reading and writing.
- Bone abnormalities: NF1 can cause skeletal abnormalities, including curvature of the spine (scoliosis) or thinning of the long bones.
- Optic gliomas: These are tumors that develop along the optic nerve, which connects the eye to the brain. They can cause vision problems or even blindness.
Neurofibromatosis Type 2 (NF2)
Neurofibromatosis type 2, also known as NF2, is a less common form of neurofibromatosis. It is caused by a mutation in the NF2 gene and affects approximately 1 in 25,000 individuals worldwide. NF2 is characterized by the development of tumors on the nerves responsible for hearing and balance.
The symptoms of NF2 typically include:
- Bilateral vestibular schwannomas: These are tumors that grow on the nerves responsible for hearing and balance. They can cause hearing loss, tinnitus (ringing in the ears), and problems with balance.
- Meningiomas: These are tumors that develop in the membranes surrounding the brain and spinal cord. They can cause headaches, seizures, or other neurological symptoms.
- Ependymomas: These are tumors that develop in the cells lining the ventricles of the brain or the central canal of the spinal cord. They can cause symptoms such as headaches, nausea, or changes in mood or behavior.
- Cataracts: Some individuals with NF2 may develop cataracts, which can cause blurry vision or difficulty seeing in bright light.
Schwannomatosis
Schwannomatosis is the rarest form of neurofibromatosis, and its exact prevalence is unknown. It is characterized by the development of schwannomas, which are tumors that grow on the nerves. Unlike NF1 and NF2, schwannomatosis does not typically involve tumors on the skin.
The symptoms of schwannomatosis can include:
- Schwannomas: These tumors can develop on any nerve in the body, causing pain, numbness, or weakness in the affected area.
- Chronic pain: Individuals with schwannomatosis often experience chronic pain, which can be severe and debilitating.
- Muscle weakness: Schwannomas can compress nerves, leading to muscle weakness or atrophy in the affected area.
It is important to note that the symptoms and severity of neurofibromatosis can vary greatly among individuals. Some people may have mild symptoms that do not significantly impact their daily lives, while others may experience more severe complications. Regular medical check-ups and monitoring are essential for individuals with neurofibromatosis to manage their condition and address any potential complications.
Schwannomatosis. Each condition has its own set of symptoms. Many of the symptoms are related to the nervous system. People with NF are at a somewhat increased risk for cancer. Many people with NF1 have 100's if not 1,000's of visible tumors all over their body. The severity of NF can vary widely from person to person. Unfortunately, not much can be done to prevent symptoms of NF. It is very important to have knowledgable doctors that can followed patients with NF closely in order to find problems that can be treated before they get worse.

Everything is worse ... tumors, gliomas, scoliosis, plexiform .....

- color buttons "café-au-lait' ;
- gliomas-optic (tumors at the level of the nerve roots of the eye) ;
- nodules of Lish (hematoma pigmentant the iris of the eye) ;
- neurofibromas of the spinal nerves, and peripheral devices ;
- with neurological and/or cognitive ;
- scoliosis ;
- anomalies of the face ;
- malignant tumors of the nerve sheath ;
- pheochromocytoma (malignant tumor located at the level of the kidneys) ;
- bone lesions.
The symptoms
The disease of Recklinghausen affects the skin and the central and peripheral nervous system. The primary symptoms associated usually appear during childhood and can affect the skin in the following way :
- tasks skin color "coffee with milk", of different sizes, different forms and can occur at any level of the body ;
- freckles developing under the arms and in the armpits ;
- the development of tumors at the level of the peripheral nerves ;
- the development of tumors at the level of the nervous system.
Other signs and symptoms may also be significant in the disease, these include :
- nodules of Lish : outgrowth affecting the eyes ;
- Pheochromocytoma : tumor of the adrenal gland, which ten percent of these tumors are cancerous ;
- enlargement of the liver ;
- a glioma : tumor of the optic nerve.
The impact of the disease on bone development, to include a small stature, deformities of the bones and scoliosis.
