Can you remove tumors from neurofibromatosis?

Can you remove tumors from neurofibromatosis?

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 are neurofibromas removed?

There are many ways to remove neurofibromas. Usually a neurofibroma is “excised”, meaning “cut out”, by a scalpel or other means; or they are “destroyed” by electrosurgery. The tumors may also be destroyed (ablated) by desiccation (dehydration or drying), or vaporized using electrosurgery.

Can NF1 tumors be removed?

People with NF1 are predisposed to developing multiple neurofibromas. Most of these tumors do not hurt or cause problems, but some may itch or be painful. Treatment consists of observation and, if necessary, surgical removal.

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.

Can neurofibromas grow back after surgery?

Because it is often hard to remove all of a plexiform, surgeons often can only take out a portion of the tumor. This is called a debulking procedure. Unfortunately, plexiform neurofibromas may grow back after surgery.

What is inside a neurofibroma?

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.

Can NF1 cause tumors?

People with NF1 are also known to have a higher risk of cancerous tumors, including a sarcoma called malignant peripheral nerve sheath tumor (MPNST), brain cancer, and breast cancer, than people without the condition.

What does a subcutaneous neurofibroma look like?

Subcutaneous neurofibromas present as firm, spherical subcutaneous nodules that are frequently painful. Plexiform neurofibromas (Figure 5) are a distinctive type of neurofibroma. This type of neurofibroma grows along the length of the nerve and often involves multiple fascicles.

What is the treatment for neurofibromas?

Complete excision of the lesion is curative. Neurofibromas are the most prevalent benign peripheral nerve sheath tumor. Often appearing as a soft, skin-colored papule or small subcutaneous nodule, they arise from endoneurium and the connective tissues of peripheral nerve sheaths.

What are neuroneurofibromas?

Neurofibromas are benign tumors of the peripheral nerve sheath. Neurofibromas present as slow-growing tumors. They typically appear after puberty. They are generally asymptomatic, but may become painful, irritated, or pruritic.

What is the difference between plexiform and subcutaneous neurofibroma?

Subcutaneous neurofibromas present as firm, spherical subcutaneous nodules that are frequently painful. Plexiform neurofibromas (Figure 5) are a distinctive type of neurofibroma. This type of neurofibroma grows along the length of the nerve and often involves multiple fascicles. Most plexiform neurofibromas are congenital or appear early in life.
