TranslationsNeurinoma
Neurinoma a benign tumor that originates in the membrane of a nerve trunk. Neurinomas are most often found in the auditory nerve. Neurinoma of the skin usually appears on the extremities and is painful. With neurinoma of the auditory nerve, noises are heard in the ear and a decrease in hearing to the point of complete deafness can occur. As the neurinoma develops further, many symptoms that are due to increased intracranial pressure arise. These include dizziness, weakness in the mimetic muscles, tremor of the eyes, and headaches. Neurinomas are treated surgically. neurinoma

Anybody familiar with schwannoma? A. A schwannoma is a kind of tumor originating from the Schwann cells. The insulating myelin sheath which covers peripheral nerves is produced by the Schwann cells. Hence, one kind of tumor originating from the Schwann cells is called a schwannoma.
Schwannomas are very homogeneous tumors consisting only of Schwann cells. The tumor cells always stay on the outside of the nerve, but the tumor itself may either push the nerve aside and/or up against a bony structure (thereby possibly causing damage). Schwannomas are relatively slow growing. For reasons not yet understood, schwannomas are mostly benign and less than 1% become malignant (degenerate into cancer). This form of cancer is known as malignant peripheral nerve sheath tumour or malignant Schwannoma or neurofibrosarcoma.
Schwannomas can arise from a genetic disorder called neurofibromatosis.
