Some tumors are formed outside the brain and spine. They’re called neurofibromas. Neurofibromas grow from nerve cells. These tumors can happen with neurofibromatosis. This condition has three main types. First, neurofibromatosis type 1 (NF1). Second, neurofibromatosis type 2 (NF2). Third, schwannomatosis. Neurofibromas in the mouth are oral neurofibromas. These growths appear in the mouth, tongue, palate, gums, and oral tissues. Oral neurofibromas start in the nerve sheath. NF1 causes oral neurofibromas. NF1 has a gene mutation. This mutation makes a faulty neurofibromin protein.
Epidemiology
NF1 happens in about 1 out of 3,000 to 4,000 newborns. It’s a common disorder involving genes affecting nerves. People with NF1 can develop neurofibromas, including in their mouths, at any age. But these growths often become more noticeable during adolescence and early adulthood. A very high percentage, around 72% to 92%, of those with NF1 have oral neurofibromas. They can grow on the tongue, palate, gums, and mouth lining.
Anatomy
Pathophysiology
People with NF1 get it from parents (inherited) or by chance (mutation). A faulty NF1 gene makes less of a protein called neurofibromin. This protein stops tumors from growing. Without enough, cells grow out of control and make tumors. The Ras pathway tells cells to grow, change, or die. Neurofibromin blocks this pathway. But when it’s missing, Ras keeps cells growing. So tumors form, like neurofibromas around nerves. They come from Schwann cells that make the nerve’s coating.
Etiology
The NF1 gene has mutations, and they cause oral neurofibromas. These tumors mostly affect Schwann cells. Mutations can happen from a parent passing them down, or they can occur randomly. If one copy of the NF1 gene is mutated, it follows an autosomal dominant inheritance pattern, and the person will show signs of the disorder. The NF1 gene controls a protein called neurofibromin, which stops cells from growing too much by blocking the Ras signaling pathway. But when the NF1 gene is mutated, neurofibromin doesn’t work right, so cells grow uncontrollably, forming tumors like neurofibromas.
Genetics
Prognostic Factors
NF1 stems from changes in the NF1 gene. It impacts oral neurofibroma growth and care. Tumor dimensions and accessibility matter. Small, reachable tumors often fare better. Most oral neurofibromas seem noncancerous. Some may exhibit unusual traits needing close monitoring. Benign as they are, there’s risk of cancerous change, notably in NF1 patients. Malignant peripheral nerve sheath tumors (MPNSTs) may develop. MPNSTs typically start in pre-existing neurofibromas. Their course proves more aggressive.
Clinical History
Children with NF1 might get mouth growths, often noticed as teens or young adults. As NF1 people grow up, these growths can pop up anywhere, even inside the mouth. Sure, NF1 is usually behind mouth growths, but sometimes they just happen without any genetic reason.
Physical Examination
Examine the mouth with care. Feel the tongue, palate, gums and cheek lining softly. Look for tumors and their color, softness/hardness, and soreness. Check if talking, swallowing, or chewing is hard from neurofibromas. Do brain and nerve tests if you think nerves are involved.
Age group
Associated comorbidity
NF1 brings light brown skin spots. It sometimes causes thinking and learning trouble. Tumors near the optic nerve may harm sight. High blood pressure happens a lot. Mouth tumors aren’t often dangerous. However, they can sometimes turn nasty, becoming aggressive soft tissue sarcomas called MPNSTs.
Associated activity
Acuity of presentation
Some people have oral neurofibromas but don’t know it. These growths inside the mouth don’t cause problems at first. Doctors or dentists might find them during checkups. People don’t feel pain or other issues when the growths are small. As they get bigger, problems can start happening slowly. Oral neurofibromas are soft lumps that don’t hurt. You can see or feel them in your mouth. How much trouble they cause depends on where they are growing. Some areas of the mouth are more likely to have noticeable growths.

Treatment Paradigm
Removing oral neurofibromas is a common treatment. This is done through surgery. Doctors use special techniques. They carefully take out the tumor. They try not to damage nearby nerves. If the tumor is likely cancer, more treatment may be needed. Doctors may remove a larger area. This is called wide surgical excision. Sometimes, complete removal is not possible. In those cases, palliative care helps manage symptoms. People with NF1 should get genetic counseling. Counselors explain the condition’s effects. They discuss genetic risks and health issues.
Keeping your mouth healthy is important. Go for regular dental checkups. Brush and floss your teeth well. This helps stop mouth tumors from causing problems. Be gentle when cleaning your teeth. This prevents mouth injuries. Speech therapy helps if tumors affect talking or swallowing. Tumors in the tongue or mouth can make this hard. Talk to your doctor about pain relief options. Some mouth tumors can cause pain.
Role of MEK Inhibitors
Selumetinib is a medicine that stops cell growth and spread. It works on a pathway called MAPK/ERK. Doctors study it to treat a disease named neurofibromatosis type 1 (NF1). NF1 can cause tumors called plexiform neurofibromas. Selumetinib may help treat these tumors.
Doctors give medicine to make you sleep during big or multiple surgeries to remove neurofibromas. The doctors cut out the neurofibroma very carefully. They try hard not to hurt the nerves or other body parts nearby. After surgery, the doctors watch for problems like infection or too much bleeding.

People with NF1 may get oral neurofibromas. Doctors find these during check-ups. They watch the tumors closely. This means looking at them and taking pictures to see if they are growing. If the tumors cause pain or problems, doctors may treat them. Sometimes surgery is needed to remove the tumor. But regular check-ups help spot issues early.
