What is the medical term for soft tissue tumor?
Soft tissue sarcoma: A malignant tumor that begins in the muscle, fat, fibrous tissue, blood vessels, or other “soft” supporting tissues of the body. Soft tissue sarcomas do not originate in bone or cartilage.
What is the difference between neurofibroma and schwannoma?
Neurofibromas are benign, heterogeneous peripheral nerve sheath tumours arising from the connective tissue of peripheral nerve sheaths, especially the endoneurium. Schwannomas are benign encapsulated tumours originating from the Schwann cells of the peripheral nervous system.
What is tumor of the nerve tissue?
Nerve tumors are abnormal masses that grow on or in peripheral nerves, the nerves that branch from the brain and spinal cord through the rest of the body. Nerve tumors develop in the nerve sheath (protective covering) and support tissue. Most are benign.
Are soft tissue tumors painful?
Pain. The majority of soft tissue masses are painless — unless they are irritating a nerve nearby – and this is a primary reason why many masses are not diagnosed until they have developed significantly in size.
Are all soft tissue tumors cancerous?
There are many types of soft tissue tumors, and not all of them are cancerous. Many benign tumors are found in soft tissues. The word benign means they’re not cancer. These tumors can’t spread to other parts of the body.
Do nerve sheath tumors hurt?
Nerve sheath tumors include schwannomas, neurofibromas and others. They grow slowly but may eventually press against the spinal cord or nerve and cause pain or loss of function.
Can nerve tumors be removed?
Surgery. You may need surgery to remove a peripheral nerve tumor. The goal of surgery is to remove the entire tumor without damaging nearby healthy tissue and nerves. When that isn’t possible, surgeons remove as much of the tumor as they can.
Where are nerve tumors located?
Malignant peripheral nerve sheath tumors can occur anywhere in the body, but most often occur in the deep tissue of the arms, legs and trunk. They tend to cause pain and weakness in the affected area and may also cause a growing lump or mass.
