Schwannomas may rarely arise from the facial nerve and most commonly occur in the intratemporal part of the nerve. Extratemporal facial nerve schwannomas are extremely rare. Intraparotid schwannomas usually develop in adults and only one pediatric case has hitherto been reported. Herein, we reported the second case of facial nerve schwannoma in a 7-year-old boy who presented with a slow growing, painless preauricular mass of three-year history. Superficial parotid ultrasonography revealed a solid mass with homogenous echogenicity originating from the superficial parotid lobe. There was no facial nerve dysfunction. Superficial parotidectomy was performed. The main truncus and main branches of the facial nerve were found intact. The mass, nearly 3x3 cm in size, was originating from a communicating nerve between the marginal mandibular and buccal branches of the facial nerve. The tumor was removed together with this communicating branch. Histopathologic examination revealed schwannoma. Facial nerve functions were normal after the operation, and no recurrence was encountered in a six-month follow-up.

D008297 Male Males
D009442 Neurilemmoma A neoplasm that arises from SCHWANN CELLS of the cranial, peripheral, and autonomic nerves. Clinically, these tumors may present as a cranial neuropathy, abdominal or soft tissue mass, intracranial lesion, or with spinal cord compression. Histologically, these tumors are encapsulated, highly vascular, and composed of a homogenous pattern of biphasic fusiform-shaped cells that may have a palisaded appearance.

D005155 Facial Nerve Diseases Diseases of the facial nerve or nuclei. Pontine disorders may affect the facial nuclei or nerve fascicle. The nerve may be involved intracranially, along its course through the petrous portion of the temporal bone, or along its extracranial course. Clinical manifestations include facial muscle weakness, loss of taste from the anterior tongue, hyperacusis, and decreased lacrimation.
