Brachial Plexus Schwannoma - Case Report and Literature Review.

Acta Clin Croat 2018 Jun;57(2):366-371

Department of Pathology, Merkur University Hospital, Zagreb, Croatia.

Schwannoma as an extracranial nerve sheath tumor rarely affects brachial plexus. Due to the fact that brachial plexus schwannomas are a rare entity and due to the brachial plexus anatomic complexity, schwannomas in this region present a challenge for surgeons. We present a case of a 49-year-old female patient with a slow growing painless mass in the right supraclavicular region that was diagnosed as schwannoma and operated at our department. Read More

Department of Dermatology, Los Angeles Medical Center (LAMC), Southern California Kaiser Permanente, Los Angeles, California.

Schwannoma involving the blood vessels is a rare phenomenon. So far, only three cases of intravascular schwannoma have been described (all of which were intraluminal), and the origin of the schwannoma in such cases is not yet completely understood. Here, we describe a very rare intramural venous schwannoma in the subcutaneous right prepatellar area of a 31-year-old man. Read More

Brachial plexus schwannoma mimicking cervical lymphadenopathy: A case report with emphasis on imaging features.

Medicine (Baltimore) 2018 Oct;97(42):e12880

Gyeongsang National University School of Medicine, Jinju.

Rationale: Brachial plexus schwannomas are rare benign tumors that are derived from Schwann cells. Because they are rare, and because of the complexity of the anatomy of the neck, these tumors can be a challenge to diagnose for radiologists and clinicians. In the present study, we describe a clinical case of brachial plexus schwannoma detected on ultrasonography (US), computed tomography (CT), and magnetic resonance imaging (MRI), and presenting as a palpable neck mass.

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

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

Department of Urology, The Second Affiliated Hospital, Xi'an Jiaotong University.

Rationale: 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 are benign and the primary treatment choice for retroperitoneal schwannomas is surgical excision, however, the involvement of the urinary system is scarcely reported.

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

Department of Emergency Medicine, The Second Xiangya Hospital, Central South University, Changsha, Hunan, China.

Rationale: 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 glands and head and neck region. However, MRS involving spine is extremely rare.

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

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

Rationale: 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.

Patient Concerns: A 54-year-old man consulted for the right sciatica-like leg pain that had aggravated 1 year ago. Read More

World Neurosurg 2018 Nov 23;119:335-339. Epub 2018 Aug 23.

Department of Neurosurgery Tianjin Medical University General Hospital, Heping District, Tianjin, China. Electronic address:

Background: Malignant peripheral nerve sheath tumor (MPNST) is a kind of rare neurogenic malignancy, which usually arises from nerve fibers in any tissue and organ that have nerve fiber distributions, especially the trunk and extremities, but it is extremely rare in spinal canal.

Case Description: We report a 30-year-old woman who had a history of excision of intraspinal occupying lesions 5 times and the pathologic diagnosis based on histomorphologic and immunohistochemistry was schwannomatosis, which existed in her family history.

Ear and Temporal Bone Pathology: Neural, Sclerosing and Myofibroblastic Lesions.

Head Neck Pathol 2018 Sep 1;12(3):392-406. Epub 2018 Aug 1.

Division of Anatomical Pathology, Department of Pathology and Laboratory Medicine, The Ottawa Hospital/University of Ottawa, 501 Smyth Road, Ottawa, ON, K1H 8L6, Canada.

Neural, sclerosing, and myofibroblastic lesions of the ear and temporal bone present diagnostic challenges for both clinicians and pathologists due to significant overlap in their clinical presentations, histologic appearances, and immunohistochemical profiles. While some of these lesions, such as schwannomas, are relatively common, others are rendered even more difficult because they are encountered very rarely in routine surgical pathology practice. This review is intended to provide an update on the pathology of some of the most commonly encountered primary diagnostic entities for the ear and temporal bone, and includes the following neural lesions: schwannoma, meningioma, and encephalocele/meningocele.

BMC Res Notes 2018 Jul 28;11(1):520. Epub 2018 Jul 28.

Institute of Neuropathology, University Hospital Münster, Münster, Germany.

Objective: Malignant peripheral nerve sheath tumors (MPNST) are aggressive sarcomas characterized by high recurrence rates and early metastases. These tumors arise more frequently within neurofibromatosis type 1 (NF1) and present with resistance during standard chemotherapy leading to increased mortality and morbidity in those patients. In vitro all-trans retinoic acid (ATRA) and MEK inhibitors (MEKi) were shown to inhibit tumor proliferation, especially when applied in combination. Read More

Objective:: Prior studies advocate the subjective visual differences between meningioma and schwannoma on T weighted images, however objective measurement of signal intensity differences may be useful in certain cases. The aim of this study was to investigate whether an objective evaluation of SIs on T weighted images would be useful to differentiate spinal schwannomas from meningiomas.

Background: Schwannomas of gastrointestinal tract are rare, mostly benign and notably different neoplasms from conventional schwannomas that arise in soft tissue or the central nervous system.
