Schwannoma is a benign neoplasm originating from Schwann's cell. It involves neurons and axons of peripheral nerves. This tumor has a predilection for the head and neck region, and often occurs as soft tissue lesion. Intraosseous sheath tumors are rare, comprising less than 1% of all bone tumors; the mandible is the most common site.

Abstract Reports of melanotic nerve sheath tumors of Schwann cell origin are rare, only three having been found in the literature. Two new cases of spinal intradural melanotic nerve sheath tumors are reported and the literature is reviewed. Controversy has arisen in regard to the origin of melanin within these tumors.

Schwannoma which originated from Schwann cells is a nerve sheath tumour. Schwannomas of the urogenital tract are very rare. We present a case of a juxtadrenal schwannoma in a 66 years old female patient. To date only three juxtadrenal schwannoma cases have been described in the literature.

AbstractIntralabyrinthine schwannomas are rare tumours which present with symptomssimilar to Meniere's disease. Preoperative diagnosis is rarely possible and most are foundincidentally during labyrinthectomy for persistent vertigo. A further case of this tumouris reported together with a review of the literature.

Schwannomas are benign nerve-sheath tumors that arise from Schwann cells. They can present as endobronchial lesions with symptoms of obstruction and hemoptysis. We describe the first case of multiple endobronchial schwannomas at 3 different sites in a single patient. The autofluorescence ratio was

The extrapancreatic nerve plexus may give rise to schwannomas. The aim of this study was to define the clinicopathologic features of peripancreatic schwannoma and to allow improved diagnosis and treatment for this condition.A retrospective analysis was performed on 17 patients with pathologically proven peripancreatic schwannoma (defined as schwannoma ...

Two cases of unsuspected intralabyrinthine schwannoma are reported and the literature is reviewed. The mean age of the patients was 56 years, with the most common symptoms being hearing loss, dizziness, and tinnitus. All patients demonstrated a profound sensorineural hearing loss with low discrimination scores, and recruitment was elicited in two ...
