a tumor of peripheral nerves due to abnormal proliferation of Schwann cells; called also fibroneuroma.

neu·ro·fi·bro·ma

(nū'rō-fī-brō'mă),
A moderately firm, benign, encapsulated tumor resulting from proliferation of Schwann cells in a disorderly pattern that includes portions of nerve fibers; in neurofibromatosis, neurofibromas are multiple.

[noo͡r′ōfībrō′mə] pl. neurofibromas, neurofibromata
Etymology: Gk, neuron + L, fibra, fiber; Gk, oma, tumor

neurofibroma

a tumor of peripheral nerves due to abnormal proliferation of Schwann cells. In cattle neurofibromas appear as subcutaneous swellings. They seem to be transmitted from a cow to her calf. Called also fibroneuroma, schwannoma.

Los neurofibromas deben ser distinguidos de los schwanomas, en los que los remanentes de los fasciculos del nervio principal son desplazados a la periferia y permanecen en la superficie del tumor, mientras que en el neurofibroma las fibras nerviosas tienden a encontrarse distribuidas en todo el tumor o localizadas en el centro.
Los tumores de la vaina neural se clasifican en benignos y malignos, los primeros incluyen al schwanoma, neurofibroma y los ultimos comprenden al sarcoma neurogenico.
Un estudio de revision en 903 casos de Schwanomas vestibulares (99) mostro que luego un seguimiento radiologico de 3 anos promedio, en la mitad de los casos se documento crecimiento tumoral, un 37% perdio audicion util y un 20% debio ser operado por haberse hecho sintomaticos.
De manera similar a lo expuesto anteriormente en Schwanomas vestibulares, tambien en los meningiomas existen reportes de tratamientos de radioterapia estereotaxica fraccionada.
