打印 概述A neurofibroma is a type of peripheral nerve tumor that forms a soft bump on or under the skin. The tumor can develop within a major or minor nerve anywhere in the body. This common type of nerve tumor tends to form centrally within the nerve. A neurofibroma forms on the protective covering of the nerve, known as the nerve sheath. Sometimes it grows on several nerve bundles. When this happens, it's called a plexiform neurofibroma. A neurofibroma may cause mild symptoms or no symptoms at all. If the tumor presses against nerves or grows within them, it may cause pain or numbness. A neurofibroma usually isn't cancer. Rarely, it can become cancer.产品与服务书籍:《妙佑医疗国际家庭健康手册》第 5 版简报:妙佑医疗国际卫生来信 — 数字版显示妙佑医疗国际的更多产品 Types 听神经瘤 恶性周围神经鞘瘤 硬纤维瘤 神经纤维瘤 神经鞘瘤 良性周围神经肿瘤 症状A neurofibroma might cause no symptoms. If symptoms occur, they're usually mild. When a neurofibroma grows on or under the skin, symptoms may include: A bump on the skin. The bump may be the color of your skin or pink or tan. Pain. Bleeding. If a neurofibroma becomes large or presses against or grows on a nerve, symptoms may include: Pain. Tingling. Numbness or weakness. Change in appearance when a large neurofibroma is on the face. Some people with neurofibromas have a genetic condition known as neurofibromatosis type 1 (NF1). A person with NF1 may have many neurofibromas. The number of neurofibromas increases with age. A tumor that involves many nerves, known as a plexiform neurofibroma, can occur in a person with NF1. This type of neurofibroma can grow large and cause pain. It also can become cancerous. 申请预约 病因A neurofibroma can arise with no known cause, or it may appear in people with a genetic condition called neurofibromatosis type 1. Neurofibromas most often are found in people ages 20 to 30 years old. 风险因素The only known risk factor for neurofibromas is having the genetic condition known as neurofibromatosis type 1 (NF1). People with NF1 have several neurofibromas, along with other symptoms. In about half of the people with NF1, the disease was passed down from a parent. However, most people with neurofibromas don't have NF1. 来自妙佑医疗国际员工 申请预约 July 19, 2024 打印 显示参考文献 Neurofibroma. American Brain Tumor Association. https://www.abta.org/tumor_types/neurofibroma.
