Abstract
Neurilemmoma (schwannoma) is a benign, encapsulated perineural tumor of neuroectodermal derivation that originates from the Schwann cells of the neural sheath of motor and sensitive peripheral nerves. Schwannomas are commonly seen in the head and neck region, flexor surface of extremities. However, schwannoma can arise from any cranial or spinal nerve as a globoid encapsulated tumor. We report a case series of four cases of schwannoma arising from four unusual sites one presenting as a parotid tumor; second one as a pleural mass, third as parapharyngeal mass and the fourth one as a nasal mass.
