“…There are no remarkable symptoms or signs in the early stage of the disease, especially schwannoma of the neck, which is often palpated incidentally. In the later stage of the disease, schwannoma often presents as relevant symptoms and signs based on the anatomic structures involved and its size, such as dysphasia, nasal obstruction, painless swelling of the cheek, and dyspnea while patient is in supine position 3,5,8 . In this study, similar symptoms were found, including nasal obstruction in nasal schwannoma and dysphasia in parapharyngeal space schwannoma.…”

“…Tumor cells were positive for S100 protein and vimentin and negative for EMA and desmin in all the cases. This finding was consistent with the literature [9]. CD34 was reported to be positive in some epithelioid schwannomas that were composed of spindled to predominantly epithelioid cells without mitoses, presenting with an infiltrative growth pattern, and typically occurring in the colon or bladder.…”

Aims: Compared with those in other head and neck regions, schwannomas in the nasal cavity or paranasal sinuses are rare. The aim of this study was to present the experience of the authors in 11 schwannoma cases of the sinonasal tract and pterygopalatine fossa over a decade. Methods: A retrospective study from 2003 to 2014. Results: Three female and 8 male patients from 22 to 61 years of age (mean age 42 years) were admitted. The most common complaints were unilateral nasal congestion. A total of 10 of the patients received surgery, including 6 functional endoscopic sinus surgeries (FESS). The postoperative course was generally uneventful. Among the patients, 10 remained regionally asymptomatic, and there has been no clinical or radiological evidence of recurrence or residual tumor. Conclusion: Surgical treatment is effective for schwannomas of the sinonasal tract and the pterygopalatine fossa with a low recurrence rate. Conducting CT and MRI (particularly fluid-attenuated inversion recovery) before surgery is mandatory. FESS could become the primary treatment of choice.

“…[4,7] Although originating most frequently from sensory nerves, head and neck schwannomas can occur in all cranial nerves except the olfactory or optic nerves, which are extensions of white matter. Schwannomas involving cranial nerve eight are located intracranially and comprise 90% of intracranial schwannomas.…”

“…[1] Intraparotid, nasal/paranasal, mastoid, parapharyngeal, hypopharyngeal, tongue base or cervical locations are considered extracranial schwannomas. [1,2,4,7] Unusual extracranial locations include the esophagus, larynx, and thyroid gland. [2] In terms of neck site, extracranial head and neck schwannomas (ECHNS) can be medial or lateral.…”

Objectives: This study aims to evaluate patients operated due to extracranial head and neck schwannomas. Patients and Methods:A total of 14 patients (6 males, 8 females; mean age 42.6 years; range 7 to 73 years) who were treated for extracranial head and neck schwannomas between January 1995 and December 2015 were retrospectively reviewed. Demographic data, tumor location, surgery, and clinical characteristics of the patients were discussed in light of the literature.Results: All patients were evaluated radiologically and with fine needle aspiration biopsy preoperatively. Total removal of the tumor was achieved in all patients. All tumors had benign character. Mean follow-up period was 14 months. Recurrence or malignancy was not detected in any patient.Conclusion: Schwannomas may present in a variety of sites in the head and neck region, and cause usually non-specific symptoms. Therefore, the preoperative diagnosis requires a clinical suspicion. Preoperative magnetic resonance imaging is a useful and simple method for diagnosis. Sonuç: Schwannomlar baş boyun bölgesinde farklı alanlarda ortaya çıkabilir ve genellikle non-spesifik semptomlara yol açar. Bu nedenle, tanı için klinik şüpheye ihtiyaç vardır. Ameliyat öncesi manyetik rezonans görüntüleme tanı için yararlı ve kolay bir yöntemdir.Anahtar Sözcükler: Baş boyun neoplazmları; sinir kılıfı neoplazmları; nörilemmom; Schwann hücreleri.
