Schwannoma

Common Name(s)

Schwannoma

Schwannomas are tumors of the tissue that covers the nerves (nerve sheath). These tumors develop from a type of cell called a Schwann cell, which gives them their name. They are usually benign (not cancerous). Although schwannomas can arise from any nerve in the body, the most common areas include the nerves of the head and neck and those involved with flexing in the arms and legs. Common symptoms include a slow-growing mass and Tinel shock (an electric-like shock when the affected area is touched). The cause of schwannomas is unknown, but they sometimes occur in people with certain disorders including some types of neurofibromatosis. Benign schwannomas are typically treated with surgery.

Surgical management of retroperitoneal schwannoma complicated with severe hydronephrosis: A case report.
 

Author(s): Liandong Zhang, Ming Gao, Tongdian Zhang, Tie Chong, Ziming Wang, Wenpin Liu, Hecheng Li

Journal: Medicine (Baltimore). 2018 Sep;97(39):e12528.

 

Schwannomas are usually benign tumors arising from well-differentiated schwann cells, which rarely occur in the retroperitoneal space. The lack of specific signs and radiologic imaging characteristics makes preoperative diagnosis rather difficult. Most retroperitoneal schwannomas ...

Lumbar intraspinal microcystic/reticular schwannoma: Case report and literature review.
 

Author(s): Congcong Liu, Lianqi Yan, Qing Liu, Jing Li, Hongtao Jin, Jingcheng Wang, Youwen Deng

Journal: Medicine (Baltimore). 2018 Sep;97(39):e12474.

 

Microcystic/reticular schwannoma (MRS) is a rare histological variant of schwannoma which was initially described in 2008 with a predilection for the visceral organs. This distinct tumor had been reported to mainly affect gastrointestinal tract, subcutaneous and soft tissue, various ...

False localizing sign caused by schwannoma in cervical spinal canal at C1-2 level: A case report.
 

Author(s): Jun Mo Park, Ji Hyo Kim

Journal: Medicine (Baltimore). 2018 Sep;97(36):e12215.

 

False localizing sign means that the lesion, which is the cause of the symptom, is remote or distant from the anatomical site predicted by neurological examination. This concept contradicts the classical clinicoanatomical correlation paradigm underlying neurological examinations.

A Small Glossopharyngeal Schwannoma Presenting with Intractable Vomiting: Case Presentation and Literature Review.
 

Author(s): Houssein Darwish, Badih Adada

Journal: World Neurosurg. 2018 Jul;115():101-104.

 

Glossopharyngeal schwannomas are rare tumors. Clinical and radiologic presentation closely resembles those of vestibular schwannomas. Their clinical presentation varies from vestibulocochlear dysfunction to glossopharyngeal and vagal nerve dysfunction.

"Ancient" schwannoma of the submandibular gland: A case report and literature review.
 

Author(s): Che-Fang Ho, Pei-Wen Wu, Ta-Jen Lee, Chien-Chia Huang

Journal: Medicine (Baltimore). 2017 Dec;96(51):e9134.

 

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.
