“…Schwannomas can be divided into assortment subtypes based on the histological findings, such as ancient, microcystic-reticular, epithelioid, cellular, psammomatous, and melanotic types. [ 4 ] Ancient schwannoma is a relatively rare variant. It was first described by Ackerman and Taylor in 1951, [ 5 ] characterized by increased cellularity and atypia.…”

“…With schwannoma developing within a salivary gland, patients usually describe a painless and mobile mass in the region of the affected gland. [ 4 ] These benign tumors tend to push the associated nerve aside, which accounts for their usually asymptomatic presentation. Generally, patients seek medical advice until the tumors become large to make cosmetic concerns or cause compression to their adjacent structures.…”

Rationale:Schwannomas are solitary neurogenic tumors that arise from cells of the neural sheath. Ancient schwannoma is a relatively rare variant of schwannoma, characterized by increased cellularity and atypia. These cellular changes could be confusing and make the accurate pathologic diagnosis difficult.Patient concerns and diagnoses:A 36-year-old man presented with painless swelling in left submandibular region for more than 2 years. The computed tomography confirmed a well-defined cystic lesion in the left submandibular space, which caused superior and posterior displacement of the left submandibular gland. Surgical excision was performed and the pathology confirmed the diagnosis of ancient schwannoma. To our knowledge, this patient is the second case of primary submandibular ancient schwannoma reported in the literatures.Interventions and outcomes:The patient underwent tumor resection and postoperative recovery was uneventful. There were no nerve deficits after the operation. There was no recurrence within 1 year of follow-up.Lessons:Schwannoma originated from the submandibular gland is extremely rare and only a few cases have been reported. Ancient schwannoma is an even more rare tumor. The increased cellularity and atypia of ancient schwannoma can resemble features of malignancy. Great care must be taken to make differential diagnosis with fibrosarcomas and malignant schwannoma.

“…Schwannomas are solitary, benign, slow-growing, and well-encapsulated neurogenic tumors arising from the myelin-producing cells of the neural sheath [1]. These tumors can occur anywhere in the body, most located in the head and neck region.…”

“…Depending on the tumor's location and size, some patients may experience symptoms like dysphagia, hoarseness, or tongue atrophy. Given their indolent nature, slow growth, and clinical and radiological resemblance to other benign and malignant salivary gland lesions [5], these tumors can remain asymptomatic for extended periods, making diagnosis even more challenging [1]. Understanding hypoglossal schwannomas' clinical, radiological, and histopathological features is crucial for accurate diagnosis and appropriate treatment.…”

Background: Schwannomas are solitary neurogenic tumors originating from the myelin-producing cells of the neural sheath. Hypoglossal nerve schwannomas are exceedingly rare, particularly those extracranially originating and mimicking a submandibular salivary gland tumor. Methods: We report the case of a 31-year-old female who presented to our ENT department with a painless swelling in her left submandibular region that has persisted for approximately five months. Discussion: Due to the rarity of these tumors and their unique nature, a comprehensive diagnostic workup is imperative for accurate diagnosis. Surgical excision remains the gold standard treatment. Conclusions: Extracranial hypoglossal nerve schwannomas represent a rare clinical entity requiring a thorough diagnostic process for precise identification. The preferred treatment strategy for managing hypoglossal gland schwannomas involves complete tumor excision while preserving the facial nerve.

“…Schwannoma arises from Schwann cells of nerve sheath of peripheral motor, sensory, sympathetic nerves, the cranial nerve pairs with the exception of the optic and olfactory nerves. These nerves do not have a Schwann cell sheath [3][4][5]. Locating the nerve of origin is difficult and only 50 % of all cases can be correlated with the nerve of origin [6].…”

Giant paratracheal ancient schwannoma in 57-year-old male patient: case report

et al. 2014

Background A 57-year-old male patient presented with a massive paratracheal tumor was admitted for tumor extirpation. The presented tumor was exposed by a growth spurt in approximately 6 months' time. This manifested in tracheoesophageal compression symptoms (tracheal deviation on roentgenography, significant dyspnea, and dysphagia). Surgical extirpation was recommended as a treatment of choice.Method After positioning patient with rotated head on the contralateral side, a longitudinal incision was made on the anterior border of the sternocleidomastoid muscle extending from the clavicular head to the retromandibular area. The tumor was carefully dissected from structures present in the carotid sheath and fully extirpated in one piece from its bed, which extended proximally to the collar bone and cranially to the angle of the mandible. A histological examination of the extirpated tumor was performed.Results After the paratracheal tumor was extirpated, an instant relief from the tracheoesophageal compression symptom was described by the patient. Final diagnosis was determined by a histological examination as an ancient schwannoma.Conclusion Currently, the only available treatment for this type of tumor is surgical extirpation. Histological examination is the only method that can establish final diagnosis.
