Schwannoma Located in Nasopharyngeal Region

Schwannoma of Nasopharynx-A Rare Case with A Complex Presentation

Nasopharyngeal tumors are rare, and schwannomas originating from this location are extremely uncommon. Schwannomas are tumors arising from the Schwann cells of peripheral nerve sheath which are neuroectodermal in origin. These are benign, slow growing, well-encapsulated tumors and are mostly seen in the head and neck region. We present a rare case of schwannoma with nasopharynx as its epicenter in an elderly female patient who presented with complaints of hematemesis, bilateral nasal obstruction and stertorous breathing. Diagnostic nasal endoscopy revealed a smooth mucosa covered globular mass occupying bilateral choana. Contrast-enhanced computed tomography of Nose and paranasal sinuses revealed a homogenous mass occupying the entire nasopharynx extending into the nasal and oropharyngeal cavities. The patient underwent Trans-nasal Endoscopic excision under general anesthesia. Nasopharyngeal tumors have a wide range of presentation and a high index of clinical suspicion combined with imaging modalities is required for diagnosis and pre operative planning. Some tumors can cause life-threatening airway obstruction due to delayed presentation and should be managed efficiently and meticulously, with endoscopic excision being a viable approach for cases confined within the nasopharynx.

A Rare Case of Pediatric Oropharyngeal Schwannoma

This is a case of a male child who presented with a progressively enlarging oropharyngeal mass, hyponasal voice, and symptoms of obstructive sleep apnea. Computed tomography imaging of the head and neck revealed a well-circumscribed low-density area of polypoid morphology arising from the left lateral pharyngeal wall, filling most of the posterior oropharynx and extending to a pedicle at the lateral nasopharynx. Histopathological evaluation following surgical excision revealed Antoni A tissue and S100 immunoreactivity. The presentation and diagnosis of benign schwannoma neoplasms are discussed.
