“…In literature, there are rare case reports of schwannoma, which manifest with cervical swelling, including the tongue, thyroid gland, intraparotid gland facial nerve, the cervical sympathetic chain, brachial plexus, and vagal nerve schwannomas. 3,[7][8][9][10][11][12][13][14] But the anteriorly extended intradural extramedullary cervical schwannoma is uncommon. 15,16 In addition to this infrequency, in our case, the intradural extramedullary lesion has an anterior extension, which causes observable and palpable neck swelling.…”

Schwannomas are typically solitary, well-encapsulated, benign tumors running along or attached to a nerve. An intradural-extramedullary cervical spinal schwannoma, which first manifests as a swelling in the anterior neck, has not been reported to the best of our knowledge. We present the case of a 69-year-old patient complaining of a gradually worsening painful left cervical swelling for over 8 years. First, a posterior spinal midline approach was performed for the resection of the tumor and the tumor portion in the vertebral canal was totally removed. The second operation, the anterolateral approach, was planned to be executed in a second surgical session. The patient was discharged from the hospital without neurological deficits. Histopathological diagnosis was a schwannoma. The first aim of surgery is to treat neurological deficits in patients with cervical intraspinal schwannomas with/without extension into the extra-vertebral paravertebral neck regions. The surgical strategy combines the posterior midline and the anterolateral cervical approaches in the same session or at different times.

“…Intraparotid schwannoma accounts for 0.2%-1.5% of all facial nerve tumors in the parotid gland. 4 Intratemporal facial nerve schwannoma presents as a nerve dysfunction in the form of facial paresis while extratemporal nerve involvement presents as a parotid mass without nerve dysfunction. 5 There are no definite radiological findings of intraparotid schwannoma.6 MRI is the radiological test of choice for detecting facial nerve schwannoma.…”

Schwannoma is a benign tumor of axonal nerve sheath. Head and neck area, particularly parotid gland is an uncommon site for Schwannoma, however it can rarely arise from the intraparotid part of facial nerve and present as either a symptomless mass or facial paresis. Its diagnosis before surgical intervention is important for the conservation of parotid gland and facial nerve. On clinical examination and imaging studies, it can be misdiagnosed easily. FNAC is a helpful tool for its diagnosis. This entity should not be ignored while dealing with parotid masses. We present a case of a patient who came with the complaint of a parotid mass. Magnetic imaging resonance (MRI) scan suggested a parotid tumor which proved to be a spindle cell neoplasm on Fine Needle Aspiration Cytology (FNAC). A definite diagnosis of schwannoma of intraparotid facial nerve was made on histopathological examination of the excision sample.

“…A characteristic symptom of schwannoma is neurological deficit. Tumors originating in the sensory nerves may present as pain, those originating in the vagus nerve may present as hoarseness and globus sensations, and those originating in the facial nerves may present as facial palsy [ 6 , 7 ]. In this case, the schwannoma originated in the GAN.…”

Schwannoma, also known as neurilemmoma, is a tumor of the nerve sheath, which most often occurs in the peripheral nerves of the extremities. Schwannoma can be accompanied by symptoms such as pain, paresthesia, and Tinel sign; however, patients can also be asymptomatic. Here, we present the case of a 17-year-old woman who presented with a slowly growing, asymptomatic, postauricular mass that appeared 10 years prior. Ultrasonography was performed, and the mass was thought to be an epidermal inclusion cyst. However, the clinical manifestation during surgery was not correlated to an epidermal inclusion cyst, leading to the suspicion of schwannoma from the posterior branch of the great auricular nerve. After a meticulous dissection, schwannoma was diagnosed based on a permanent section biopsy. Postoperative complications and recurrence were not observed. Schwannoma in the peripheral nerve area of the face is rare. Therefore, an investigation of tumors that occur where the nerve passes using imaging and clinical features is necessary to confirm the diagnosis of schwannoma and to establish suitable treatment methods.
