 [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.
Synonym(s): fibroneuroma
