1. Trans-oral, Carbon Dioxide-Assisted Excision of an Unusual Schwannoma of the Tongue Base: Case Report and Review of the Literature
Abstract Introduction Schwannomas are benign, solitary, encapsulated tumors that may originate at any site of the peripheral nervous system, with the exception of the olfactory and optic nerves. Schwannomas of the base of tongue are very rare, and only sporadic cases are documented. The tongue base represents a challenge for surgeons. Carbon dioxide (CO2)

2. Schwannoma gigante de nervo ulnar: relato de caso
RESUMO Os schwannomas são os tumores benignos mais comuns dos nervos periféricos nos membros superiores. Embora muitos sejam assintomáticos, podem produzir um efeito de massa e assim comprimir os tecidos moles adjacentes ou interferir na função articular. Os autores apresentam um relato de caso e uma revisão de um caso de schwannoma gigante no nervo cu

3. Retrospective analysis of oral peripheral nerve sheath tumors in Brazilians
Traumatic neuroma, neurofibroma, neurilemmoma, palisaded encapsulated neuroma and malignant peripheral nerve sheath tumor (MPNST) are peripheral nerve sheath tumors and present neural origin. The goal of this study was to describe the epidemiological data of oral peripheral nerve sheath tumors in a sample of the Brazilian population. Biopsies requested from

4. Expression of the receiver for mannose in cells of Schwann and Schwannoma ST88-14. / Expressão do receptor para manose em células de Schwann e Schwannoma ST88-14.
The mannose receptor (MR) is a transmembrane glycoprotein that is expressed in several cell types but little or no information is available on Schwann cells (SC). We show that rodent SC in primary cultures of dissociated cells or explant nerve cultures and a human Schwannoma cell line (ST88-14) bind the exogenous MR ligand neoglycoprotein mannosyl/bovine ser

5. Intrascleral neurilemmoma.
The case of an anteriorly situated, intrascleral, neurilemmoma in an 11-year-old girl is reported. Only two similar cases have been described in the literature, and the diagnosis was made only after detailed histological examination, including electron microscopy and specialised staining techniques, to differentiate a neurilemmoma (schwannoma) from a neurofi

6. Congenital malignant neurilemmoma
A unique case of a congenital malignant neurilemmoma in a newborn baby is described.

7. Choroidal neurilemmoma--an unusual clinical misdiagnosis.
A case of choroidal neurilemmoma is reported. After a period of clinical observation which included serial fundus photography and fluorescein angiography, during which time active growth was seen, the tumour was thought to be a malignant melanoma, and enucleation was considered the treatment of choice. Subsequent histological study revealed a neurilemmoma. I

8. Neurilemmoma of the ciliary body: report of a case.
A case of ciliary body neurilemmoma is described. This neoplasm is extremely rare in the uveal tract and has been reported only once in the ciliary body. After extensive clinical studies of the rapidly growing tumour enucleation was performed. Subsequent histological examination showed typical features of highly vascular benign neurilemmoma. The main clinica

9. Intracerebral neurilemmoma.
Two examples of intracerebral neurilemmoma occurred in the absence of von Recklinghausen's disease. The first case was unique because the patient was clinically asymptomatic, and the second case was unusual with a combination of oligodendroglioma and neurilemmoma in the same mass. The latter lesion arising in persons without stigmata of neurofibromatosis has

10. Malignant neurilemmoma of left atrium.
A 31-year-old woman, whose chief complaint was back pain, was found to have an echocardiographic abnormality suggestive of a left atrial myxoma. Angiography clearly showed a large radiolucent mass protruding from the left atrium into the left ventricle during diastole. X-rays of the sacrum disclosed the presence of a malignant tumour. Biopsy specimens taken

11. Neurilemmoma of the anterior ethmoidal nerve encroaching upon the nasolacrimal duct.
The clinical, light microscopic, ultrastructural, and immunohistologic findings of a neurilemmoma encroaching upon the nasolacrimal duct are presented. This is the first reported case of this rare tumour of the nasolacrimal duct where the diagnosis has been confirmed by electron microscopy and immunohistochemical techniques.

12. Intraosseous neurilemmoma of the cervical spine causing paraparesis and treated by resection and grafting.
A neurilemmoma presented as an expanding lesion of the bodies of C6 and C7 vertebrae and caused local neurological signs together with a spastic paraparesis. This tumour was treated by preliminary posterior fusion, followed by its complete removal via an anterior approach and stabilization by anterior spinal fusion. Other cases in the literature are reviewed
