Multiple tumours of peripheral nerves are often seen in patients with neurofibromatosis of type 1 or 2. Multiple schwannomas may occur without other manifestations of neurofibromatosis. We have reviewed 12 patients with multiple schwannomas arising from peripheral lesions who did not fulfil the criteria for either type of neurofibromatosis. Four had spinal and one an intracranial lesion in addi...

We identified Charcot-Marie-Tooth disease type 1A (CMT1A) in a family with schwannomas in the spinal cord and median nerve. The CMT1A in this family showed an autosomal dominant pattern, like other CMT patients with PMP22 duplication, and the family also indicated a possible genetic predisposition to schwannomas by 'mother-to-son' transmission. CMT1A is mainly caused by duplication of chromosom...

Schwannomas are benign slow growing tumors that arise from the Schwann cells of any nerve (peripheral, cranial or autonomic). It also called nerilemmona,neurinoma spindle cell tumor etc. Extra cranial Head and Neck schwannomas usually present as solitary and well demarcated lesions. The lesion can cause secondary symptoms such as nasal obstruction,dysphagia and hoarseness, depending upon the lo...

BACKGROUND Schwannomas comprise 8% to 10% of all primary intracranial tumors. Primary intraorbital schwannomas are rare, accounting for 1% to 2% of all intracranial tumors. Schwannomas arise from Schwann cells in the myelin sheaths of sensory and cranial nerves. METHODS We present the case of a 56-year-old white man blind since 1970 who presented to an outside hospital for a painful right eye...

BACKGROUND AND OBJECTIVES Schwannomas are tumors originating from Schwann cells of the peripheral nerve sheath (neurilemma) of the neuroectoderm. Rarely, schwannomas can arise from the retroperitoneum and adrenal medulla. We describe a case of a 71-y-old woman who presented with an incidentally discovered adrenal tumor. METHODS Ultrasound and computed tomography scans revealed a lesion with s...

abstract introduction & objective: schwannoma, a benign tumor of nerve sheath origin, is commonly found in the head and neck, as well as flexor surfaces of the extremities. it can rarely occur in the breast and stomach with only a few cases being reported. case reports:   the cases are: 1) a 57-year- old man with breast mass, 2) a 58 -year -old man with gastrointestinal complaints who were fina...

  Schwannomas are benign nerve sheath tumors that originate from any anatomical site. Most of the schwannomas are found in the head, neck or limbs. Schwannoma arising in a lymph node is extremely rare. We have found only four cases in the review of the literature. We experienced a case of intranodal schwannoma in a perigastric lymph node. A 72 year-old female underwent cholecystectomy due to ...

Schwannoma or neurilemmoma are benign tumours originating from Schwann cells of the nerve sheath. They can arise from any peripheral, cranial, or autonomic nerve The treatment of extracranial head and neck schwannomas is surgical and the approach depends on the location and extent of the tumor and the nerve involved. The Authors report the case load of surgical managements of three different ex...

Benign extramedullary tumours of the foramen magnum region are largely schwannomas and meningiomas. Tumours originating from the motor part of cranial nerves, such as the VIIth, IXth, XIth and XIIth cranial nerves, are extremely rare. Hypoglossal nerve (cranial nerve XII) schwannomas are such an example, usually arising intracranially and, in exceptional cases, extending into the extracranial c...

Benign schwannoma is the most common neurogenic tumor in the mediastinum. Mediastinal benign schwannomas are most often asymptomatic and rarely accompanied by bloody pleural effusion. In the clinical analysis of 7 cases of pulmonary schwannomas, pleural effusion, and blood invasion were evident in 3 patients with malignant schwannoma. Herein, we report a rare case of giant, benign schwannoma pr...
