First described as a neurinoma by Verocay1 in 1910, a schwannoma is a slow-growing tumor that arises from the Schwann cells encapsulating peripheral nerves. It is also commonly referred to by a variety of names, including neurilemoma, neurolemmoma, and perineural fibroblastoma, but schwannoma is the preferred pathologic term, as it most specifically describes the main cells that compose the tumor. Schwannomas have a peak incidence in the second through fifth decades of life and have no predilection for sex or race. They rarely demonstrate malignant change and, along with neurofibromas, are the most common nerve sheath tumors.
