neurofibroma

 [noor″o-fi-bro´mah]
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

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.
