Dysphagia caused by giant schwannoma of the supraglottic oropharynx: A case report and review of the literature

Abstract

BackgroundSchwannomas are benign, encapsulated, peripheral nerve tumours that arise from the Schwann cell. Approximately 25%–45% of schwannomas occur in the head and neck. The most common site is the parapharyngeal space of the neck. However, schwannoma of the supraglottic oropharynx is rare.Case presentationWe report on a 35-year-old female who complained of progressive dysphagia, from whom a large schwannoma in the supraglottic oropharynx was excised through a transoral approach. No recurrence was seen after one year follow-up.ConclusionAlthough rare, schwannomas do occasionally occur in the supraglottic oropharynx. When dysphagia is present, a thorough diagnostic procedure should be performed to evaluate the morphology and function of the upper aerodigestive tract. MRI is sensitive and specific in the diagnosis of schwannoma. And the best treatment of choice is complete excision with preservation of functions.

Soft palate resection and secondary healing not to impair the velopharyngeal function? – Diagnosis and treatment of an intraoral schwannoma: A case report

“…Neurogenic tumors are classified as rare and can occur in different regions all over the body [ 1 ]. Schwannomas are benign solid tumors arising from Schwann-cells that produce the myelin sheath of peripheral nerves [ 2 ]. Malignant transformation of Schwannomas is stated around 1% [ 3 ].…”
