A neoplasm that arises from SCHWANN CELLS of the cranial, peripheral, and autonomic nerves. Clinically, these tumors may present as a cranial neuropathy, abdominal or soft tissue mass, intracranial lesion, or with spinal cord compression. Histologically, these tumors are encapsulated, highly vascular, and composed of a homogenous pattern of biphasic fusiform-shaped cells that may have a palisaded appearance. (From DeVita Jr et al., Cancer: Principles and Practice of Oncology, 5th ed, pp964-5)
Adenocarcinoma of the common hepatic duct bifurcation. These tumors are generally small, sharply localized, and seldom metastasizing. G. Klatskin's original review of 13 cases was published in 1965. Once thought to be relatively uncommon, tumors of the bifurcation of the bile duct now appear to comprise more than one-half of all bile duct cancers.

Ethylnitrosourea-induced development of malignant schwannomas in the rat: two distinct loci on chromosome of 10 involved in tumor susceptibility and oncogenesis. (1/627)Inbred rodent strains with differing sensitivity to experimental tumor induction provide model systems for the detection of genes that either are responsible for cancer predisposition or modify the process of carcinogenesis. Rats of the inbred BD strains differ in their susceptibility to the induction of neural tumors by N-ethyl-N-nitrosourea (EtNU). Newborn BDIX rats that are exposed to EtNU (80 microg/g body weight; injected s.c.) develop malignant schwannomas predominantly of the trigeminal nerves with an incidence >85%, whereas BDIV rats are entirely resistant. A T:A-->A:T transversion mutation at nucleotide 2012 of the neu (erbB-2) gene on chromosome 10, presumably the initial event in EtNU-induced schwannoma development, is later followed by loss of the wild-type neu allele. Genetic crosses between BDIX and BDIV rats served: (a) to investigate the inheritance of susceptibility; (b) to obtain animals informative for the mapping of losses of heterozygosity (LOH) in tumors with polymorphic simple sequence length polymorphisms (SSLPs); and (c) to localize genes associated with schwannoma susceptibility by linkage analysis with SSLPs. Schwannoma development was strongly suppressed in F1 animals (20% incidence). All of the F1 schwannomas displayed LOH on chromosome 10, with a consensus region on the telomeric tip encompassing D10Rat3, D10Mgh16 and D10Rat2 but excluding neu. A strong bias toward losing the BDIV alleles suggests the involvement of a BDIV-specific tumor suppressor gene(s). Targeted linkage analysis with chromosome 10 SSLPs in F2 intercross and backcross animals localized schwannoma susceptibility to a region around D10Wox23, 30 cM centromeric to the tip. Ninety-four % of F1 tumors exhibited additional LOH at this region. Two distinct loci on chromosome 10 may thus be connected with susceptibility to the induction and development of schwannomas in rats exposed to EtNU. (+info)
Schwannoma with features mimicking neuroblastoma: report of two cases with immunohistochemical and ultrastructural findings. (2/627)OBJECTIVE: A study of two cases of a rare variant of benign schwannoma showing areas mimicking neuroblastoma/peripheral primitive neuroectodermal tumour (PNET). METHODS: Sections of formalin fixed, paraffin embedded specimens were studied by tinctorial stains and immunohistochemistry, and the tissue retrieved from formalin was examined by electronmicroscopy in one case. RESULTS: The tumours were small and subcutaneous. Both showed features of benign schwannoma; one had a multinodular plexiform pattern. In addition, rosette-like structures consisting of collagenous cores surrounded by small round cells or slightly larger epithelioid cells were present. Tumour cells were positive for S100 protein, Leu7, and in one case GFAP, but were negative for neurofilament protein, synaptophysin, and MIC2. Type IV collagen surrounded individual cells. Electronmicroscopy in case 2 confirmed schwannian features (lamina, processes) and failed to show features of neuroblastoma (neuroendocrine granules). CONCLUSIONS: Benign schwannomas may contain rosette-like structures mimicking neuroblastoma/PNET. The techniques used confirmed schwannian differentiation only and eliminated neuroblastoma/PNET. These uncommon variants should be recognised by practising histopathologists to avoid erroneous diagnoses and inappropriate treatment. (+info)
Schwann cell hyperplasia and tumors in transgenic mice expressing a naturally occurring mutant NF2 protein. (3/627)Specific mutations in some tumor suppressor genes such as p53 can act in a dominant fashion. We tested whether this mechanism may also apply for the neurofibromatosis type-2 gene (NF2) which, when mutated, leads to schwannoma development. Transgenic mice were generated that express, in Schwann cells, mutant NF2 proteins prototypic of natural mutants observed in humans. Mice expressing a NF2 protein with an interstitial deletion in the amino-terminal domain showed high prevalence of Schwann cell-derived tumors and Schwann cell hyperplasia, whereas those expressing a carboxy-terminally truncated protein were normal. Our results indicate that a subset of mutant NF2 alleles observed in patients may encode products with dominant properties when overexpressed in specific cell lineages. (+info)
Probability of bilateral disease in people presenting with a unilateral vestibular schwannoma. (4/627)BACKGROUND: Some 4%-5% of those who develop vestibular schwannomas have neurofibromatosis type 2 (NF2). Although about 10% of these patients present initially with a unilateral vestibular schwannoma, the risk for a patient with a truly sporadic vestibular schwannoma developing contralateral disease is unknown. METHODS: A United Kingdom survey of 296 patients with NF2 was reviewed for laterality of vestibular schwannoma at presentation and the presence of other NF2 related features. The time to presentation of bilateral disease was calculated for patients presenting with a unilateral tumour. Mutation analysis of the NF2 gene was carried out on all available cases presenting initially with unilateral disease. RESULTS: Of 240 patients with NF2 with vestibular schwannomas, 45 (18%; 32 sporadic, 13 familial) had either a unilateral tumour or delay in detection between the first and contralateral tumours. Among those tested for NF2 mutations, eight of 27 and nine of 13 were identified among sporadic and familial cases respectively. Sporadic cases showed a high female to male ratio and 19 of 32 have not as yet developed a contralateral tumour (mean 4.1 years after diagnosis of the first). Thirteen of 32 sporadic patients developed a contralateral tumour (mean 6.5 years after the first tumour diagnosis, range 0-22 years) compared with 11 of 13 familial patients (mean delay 5 years, range 0-16 years). Seven of the 45 patients had neither a family history of NF2 nor evidence of related tumours at initial presentation (six before the age of 35 years). CONCLUSION: The risk of patients with sporadic unilateral vestibular schwannomata developing a contralateral tumour in the absence of family history or other features of NF2 is low, but those presenting with other neurogenic tumours in addition to vestibular schwannoma are at high risk of harbouring an NF2 mutation in at least a proportion of their somatic cells.

Midline cerebellar cystic schwannoma : a case report. (5/627)An extremely unusual case of a cystic schwannoma in the region of the inferior vermis and posterior to the fourth ventricle in a fifteen year old boy is reported. The cystic tumour caused partial obstruction to the outflow of cerebrospinal fluid from fourth ventricle and resulted in development of supratentorial hydrocephalus. On investigations, the schwannoma simulated a Dandy-Walker cyst. The boy presented with symptoms of increased intracranial pressure. On surgery, the lesion was not arising from any cranial nerve, nor was it attached to brain parenchyma, blood vessel or to the dura. The possible histogenesis of the cystic schwannoma in a rare location is discussed. (+info)
Association of lower cranial nerve schwannoma with spinal ependymoma in ? NF2. (6/627)A 15 year old male, who had earlier been operated for intraspinal intramedullary ependymoma, subsequently developed a right cerebello pontine (CP) angle mass. A diagnosis of right CP angle ependymoma was considered, in view of established histology of previously operated spinal lesion. Histopathological examination of the well defined extra-axial mass, which was attached with ninth cranial nerve, however revealed a schwannoma. A diagnosis of Neurofibromatosis-2 (NF2) is strongly suspected, because of well established fact, that the spinal ependymomas may have association with lower cranial nerve schwannomas in NF2. Cranial and spinal MRI screening for early diagnosis of associated, asymptomatic lesions, in suspected cases of NF2, particularly in children, is recommended. (+info)
Ventral T-1 neurinoma removed via hemilaminectomy without costotransversectomy--case report. (7/627)A 39-year-old male presented with a spinal neurinoma originating from the T-1 anterior root and located ventral to the spinal cord. The tumor was removed by hemilaminectomy with only partial facetectomy without costotransversectomy. No stabilization was necessary, and no complications secondary to surgery occurred. Costotransversectomy is not necessary for neurinoma ventral to the spinal cord within the spinal canal at T-1 level because the transverse process protrudes more laterally and the spinal canal of the T-1 vertebra is wider than at other thoracic levels. (+info)
Paediatric presentation of type 2 neurofibromatosis. (8/627)BACKGROUND: Neurofibromatosis type 2 (NF2) is a highly penetrant autosomal dominant condition predisposing affected individuals to schwannomas and meningiomas. The proportion of children presenting with meningioma or schwannoma who have NF2 is not well described, and neither is the mode of presentation in most children with the inherited disease. AIMS: To determine the frequency of childhood meningioma and schwannoma cases caused by NF2 and the mode of presentation. METHODS: The records of the Manchester Children's Tumour Registry from 1954 were searched for cases of meningioma and schwannoma. Paediatric presentation in a large UK series of NF2 was also studied. RESULTS: 18% (61/334) of patients with NF2 on the UK database presented in the paediatric age group (0-15 years), frequently with the symptoms of an isolated tumour. More than half had no family history to alert the clinician to their susceptibility. Three of 22 children presenting with a meningioma on the Manchester Children's Tumour Registry have gone on to develop classic features of NF2. CONCLUSIONS: Clinicians should suspect NF2 in children presenting with meningioma, schwannoma, and skin features, such as neurofibromas/schwannomas, but fewer than 6 cafe au lait patches, who thus fall short of a diagnosis of neurofibromatosis type 1.

Pancreatic schwannoma: a case report and an updated 40-year review of the literature yielding 68 cases | BMC Cancer | Full Text
Pancreatic schwannoma is a rare tumor. Preoperative diagnosis of pancreatic schwannoma is challenging due to its tendency to mimic other lesions of the pancreas. We describe a case of pancreatic schwannoma and present a review of the cases currently reported in the English literature to identify characteristics of pancreatic schwannoma on imaging. A 53-year-old male presented with a history of intermittent periumbilical abdominal pain and lower back pain for 1 week. Based on ultrasound (US) and computed tomography (CT) findings, we made a preoperative diagnosis of solid pseudopapillary tumor and performed a standard pancreaticoduodenectomy. Pathological examination showed that the tumor was composed of spindle cells with a palisading arrangement, and immunohistochemistry revealed strong positive staining for S-100 protein, which was consistent with a diagnosis of pancreatic schwannoma. At the 8-month follow-up visit, the patient was doing well without recurrent disease, and his abdominal pain had

N2 - Epidermal growth factor (EGF) activates many intracellular effector molecules, which subsequently influence the expression levels of many genes involved in cell growth, apoptosis and signal transduction, etc. In this study, the early response of gene expressions due to EGF treatment was monitored using oligonucleotide DNA microarrays in rat schwannoma cell lines. An immunoblotting experiment showed the successful activation of EGF receptors and an effector protein, STAT5, due to EGF treatment. The microarray study showed that 35 genes were significantly induced and 2 were repressed within 60 min after the treatment. The list of induced genes included early growth response 1, suppressor of cytokine signaling 3, c-fos, interferon regulatory factor 1 and early growth response 2, etc. According to ...
An unusual giant schwannoma of cervical sympathetic chain: a case report | Journal of Medical Case Reports | Full Text
Schwannomas are benign, well-differentiated tumors that originate from Schwann cells. Involvement of the cervical sympathetic nerve is relatively rare. Computed tomography is indispensable for the diagnosis. The treatment is surgical. Histological examination confirms the diagnosis. Horners syndrome postoperatively is supportive of the diagnosis. The rarity of giant cervical sympathetic chain schwannoma made the case of our patient interesting to report. Furthermore, our patients immense tumor size is very rare, and we could not find any similar report in the literature. Cervical sympathetic chain schwannoma is frequently confused with schwannoma of the vagus nerve on clinical and radiological examination, and its diagnosis can therefore be challenging for clinicians, radiologists, and pathologists. We report a rare case of cervical schwannoma in a 40-year-old Moroccan woman who presented with a large parapharyngeal mass. Computed tomography revealed a giant, heterogeneous, well-defined mass measuring
Dermatologic Manifestations of Neurilemmoma (Schwannoma): Background, Pathophysiology, Etiology
A neurilemmoma is a benign, usually encapsulated neoplasm derived from Schwann cells and, along with neurofibroma, constitutes one of the 2 most common benign peripheral nerve sheath tumors. The peripheral nervous system can be defined as nervous tissue outside the brain and spinal cord.
Conus medullary Syndrome secondary to Spinal Schwannoma : A report of 3 cases - IIUM Repository (IRep)
Spinal Schwannoma originates from the Schwann cells, hence it is called Schwannoma. The tumor localization is in various parts of the spinal cord, but prevails in cervical and thoracic. In the literature 70 to 80% of spinal schwannomas are reported to be intradural in location, and 15% with both intradural and extradural components. All 3 cases were female in their 4th-5th decade, presented with either low back pain, radiculopathy, weakness of both lower limbs associated with urinary incontinence. MRI revealed a well defined mass adjacent to conus medullary area located intradural, extramedullary. All three patients underwent microscopic assisted excision of the tumour. All patients had Good Early Outcome. Spinal schwannoma causing Conus Medullary Syndrome is rare. Back pain and radicular pain were most common early presenting symptoms while urinary symptoms occur later. Schwannomas typically arise from a single nerve root originating from the schwann cells. To obtain total resection, the ...
Rare presentation of pancreatic schwannoma: a case report | Journal of Medical Case Reports | Full Text
Schwannoma is a rare tumor among pancreatic neoplasms. Schwannomas vary in size, and most of them are cystic, mimicking pancreatic cystic lesions. Generally, a definitive diagnosis is made at the time of histological analysis. The mainstay treatment is surgical resection. We report an unusual presentation of pancreatic schwannoma with abdominal pain and several episodes of cholangitis in a 54-year-old Caucasian (Iranian) man. The condition was not diagnosed pre-operatively and Whipples procedure was performed. Pancreatic schwannoma is an important clinical entity to include in the differential diagnosis of pancreatic lesions. Pre-operative diagnosis is difficult but computed tomographic findings may be helpful. The tumor may also have atypical and rare presentations, such as cholangitis and weight loss. For benign tumors, simple enucleation is usually adequate, whereas malignant tumors require standard oncological resection.

Tongue-lip adhesion in Pierre-Robin sequence: Role redefined :Veena Singh, Chandni Sinha, Nishant Sahay, Ansarul Haq, Sarsij...
The triad of retrognathia, glossoptosis, and airway obstruction characterizes the Robin sequence along with the detrimental effects of mandibular hypoplasia on feeding, swallowing, and growth, which are very well described. Most of the babies are managed successfully on nonsurgical measures, but selected patients require surgical intervention in the neonatal period for survival. Conventionally, tracheostomy was done, which still remains a first-line surgical procedure for some surgeons. However, presently, most of the craniofacial centers have switched over to mandibular distraction procedures at an early stage and only sometimes tongue-lip adhesion (TLA). The literature is unclear as to which surgical procedure for securing the airway is more effective for these patients, and hence, the choice of procedure depends on the resources and surgical expertise. This article tells the tale of a neonate who survived by just placing a simple U-stitch between the tongue and lip, retracting the tongue ...

Schwannoma with features mimicking neuroblastoma: report of two cases with immunohistochemical and ultrastructural findings.
OBJECTIVE: A study of two cases of a rare variant of benign schwannoma showing areas mimicking neuroblastoma/peripheral primitive neuroectodermal tumour (PNET). METHODS: Sections of formalin fixed, paraffin embedded specimens were studied by tinctorial stains and immunohistochemistry, and the tissue retrieved from formalin was examined by electronmicroscopy in one case. RESULTS: The tumours were small and subcutaneous. Both showed features of benign schwannoma; one had a multinodular plexiform pattern. In addition, rosette-like structures consisting of collagenous cores surrounded by small round cells or slightly larger epithelioid cells were present. Tumour cells were positive for S100 protein, Leu7, and in one case GFAP, but were negative for neurofilament protein, synaptophysin, and MIC2. Type IV collagen surrounded individual cells. Electronmicroscopy in case 2 confirmed schwannian features (lamina, processes) and failed to show features of neuroblastoma (neuroendocrine granules). ...
Pathology of Epithelioid Schwannoma - A rare variant of Nerve Sheath Tumour [Infographic] - Dr Sampurna Roy MD
In 1981 Taxy et al described first two cases of epithelioid schwannoma. The clinical, gross, and light microscopic features of two epithelioid tumours were not typical of either benign or malignant schwannoma. Electron microscopic features were indicative of benign Schwann cell tumours.. In 1985 Frank et al described electron microscopic features of Schwann cells in epithelioid schwannoma.. It was first reported as cutaneous epithelioid schwannoma by Kindblom et al in 1998.. The tumors are predominantly dermal/subcutaneous in location and involve the lower limb, upper limb, trunk and head/neck. These tumors may cause diagnostic errors due to their increased cellularity and epithelioid morphology. Typical histologic features of classic schwannoma such as Antoni A and B areas, Verocay bodies, and hyalinized vessels are either absent or only present in focal areas. Strong and diffuse S-100 protein expression is seen in both benign and malignant counterparts of epithelioid schwannoma. Type IV ...

Two rare schwannomas of head and neck | Diagnostic Pathology | Full Text
Twenty-five to 45 percent of all schwannomas occur in the head and neck. Most of them arise along the vestibular portion of the eighth cranial nerve (acoustic neurinoma). They rarely originate from the peripheral facial nerve or other nerves within the parotid gland. Less than 4% of schwannomas involve the nasal cavity and paranasal sinuses. They arise from the branches of the trigeminal nerve and autonomic nervous system. We report two cases of schwannomas arisng from intraparotid facial nerve and nasal cavity. The first case diagnosed in a 62-year-old-man presented with 2-year-history of painless mass of the parotid gland. The lesion was found to be cystic through the pre operative examinations and investigations. The histology of the specimen retained an intraparotid cystic schwannoma. The second case concerned a 75-year-old-man presented with episodes of nasal obstruction, rhinorrhea, anosmia and headache. Histological study of the specimen showed fusiform cells with strongly and diffusely
Neurogenic Tumors of the Posterior Mediastinum | Adult Chest Surgery, 2e | AccessSurgery | McGraw-Hill Medical
Neural crest-derived tissues can be found throughout the body. In the thorax, neurogenic tumors are found most commonly in the posterior mediastinum (63%-96%).1-6 In fact, neurogenic tumors account for 75% of all posterior mediastinal neoplasms.3 The epidemiology of neurogenic tumors depends primarily on whether the patient is an adult or a child. Although one-third of mediastinal tumors diagnosed and treated in children are neurogenic, the incidence is only 12% to 14% in adults.7,8 Adults also have a lower rate of malignancy (5%-10% in adults compared with 40%-60% in children) (Fig. 162-1).1,7 The most common neurogenic tumors in adults arise from the nerve sheath (e.g., neurilemmoma and neurofibroma), whereas in pediatric populations the cells of origin are the ganglia (e.g., ganglioneuroma and neuroblastoma) (Table 162-3).1,9,10 ...
Schwannoma Survivors & Schwannoma Fighters: Schwannomas, a Story of Discounted Tumors and Misunderstood Pain
Awhile back I was doing more online reading on Schwannomas and I came across a discussion where several people mentioned that they didnt like the word survivor being used in association with Schwannomas. Our page and blog are called Schwannoma Survivors & Schwannoma Fighters so I took some time to think about it. Of course, a person may self-identify any way they wish. They can call themselves a flying goat headed crocodile zombie if they like! :) How a person self-identifies is very personal, and they have that right to assert whatever label they wish in a non-harmful manner. All of this called to mind the first thought I had when I thought about Schwannomas being discounted tumors - and that is, that if we have no mental frame of reference for understanding a Schwannoma, especially on a societal level - it would stand to reason that some people may not understand why some of us prefer to call ourselves Survivors. (And for some, no amount of suffering is enough to raise to this level ...

These nodules were slow-growing, with an average of 13.3 months from onset to presentation. Most cases were accompanied by airway obstruction, indicated by symptoms of dysphagia, dysarthria, snoring, and sleep apnea. Overall, the histological studies were consistent with a benign schwannoma with a ...
Schwannoma with an Uncommon Upper Lip Location and Literature Review
Schwannomas are usually single, encapsulated, and benign tumors of the nerve sheath that arise from the perineural Schwann cells. Schwannomas are mostly seen in the fourth decade. Despite its location in the head and neck region is 25–45%, lip location of schwannoma are very rare. We present a case of a upper lip schwannoma in the pediatric age and review the literature.

Retroperitoneal schwannoma mimicking an adnexal mass in pregnancy | BMJ Case Reports
A 36-year-old pregnant woman attended her first trimester scan and there was an incidental finding of a right-sided complex cystic adenexal mass. Further investigations including repeat pelvic ultrasound scans and MRI were performed due to its complex nature but were inconclusive. Multidisciplinary team review of images found the mass to be retroperitioneal, neurogenic in origin and involving the L5 vertebrae. The pregnancy continued to term and the baby was delivered at 39 weeks gestation by elective caesarean section due to the mass being likely to obstruct progress in labour. Postnatal biopsy confirmed a schwannoma. Plans were made for resection however as the woman was asymptomatic she declined surgery in favour of completing her family. She conceived again 2 years later and a second pregnancy was managed in the same way. The size of the schwannoma remained stable throughout this period. ...
EURORAD - Radiologic Teaching Files
Schwannomas are benign, slow-growing tumors of the nerve that may arise on cranial, spinal as well as peripheral nerves. Although relatively common intra-cranially accounting for 8% of all intra-cranial tumors, they seldom arise primarily within the infra-temporal fossa. This location is one of the least common anatomical sites for extra-cranial schwannommas whereas the pharyngeal area is the most frequent one (1). When they are located in the infratemporal fossa they usually extend intra-cranially (1) Schwannomas of the infra-temporal fossa can occur at any age with a peak incidence between the 2nd and the 4th decades with no sex prevalence (1, 4). Infratemporal location of schwannomma should incite to look for neurofibromatosis type II (NF-2)(1, 3) Pathologically, they are S-100 protein positive on immunohistochemical studies and they show two distinct areas unlike neurofibromas called Antoni A type and Antoni B type. The former is highly cellular and the latter is hypocellular , rich in ...
Lingual Schwannoma | Abstract
Schwannomas are benign tumors of nerve sheath and quite uncommon in oral cavity. The case of a 15 yr old male is presented who had a 4 months history ..
2The Second Hospital of Jilin University, Department of Neuroscience, Changchun, Jilin, China DOI : 10.5137/1019-5149.JTN.8153-13.0 Melanotic schwannoma is a rare Schwann cell tumor characterized by the deposition of melanin in the cell cytoplasm. Melanotic schwannoma varies greatly in terms of morphology and clinical manifestations. Here, we describe a patient with subdural extramedullary melanotic schwannoma of the thoracic spinal cord. The 47-year-old man presented with pain in his chest and back that had lasted a year, numbness and weakness in both his lower extremities for 20 days, and urinary retention for 4 days. Magnetic resonance imaging (MRI) revealed a subdural extramedullary lesion at the level of the T2-T4 thoracic spinal cord. A total resection of the mass was performed. A diagnosis of melanotic schwannoma was made based on the histopathological examination. During the six-month follow-up period, no recurrence of the tumor was observed. A long-term follow-up will be necessary to ...
Antoni Esteve Subirana - Wikipedia
Antoni Esteve i Subirana was the fifth in a long lineage of pharmacists beginning in 1787 with Tomàs Esteve i Gabanyach at the Plana de lOm (Manresa) pharmacy, where the seventh generation of pharmacists in the Esteve family continues to work today. Antoni Esteve was awarded an honors degree in pharmacy from the University of Barcelona in 1924 and started his doctoral studies in Madrid the following year. His plans to write his thesis in chemistry in Barcelona were interrupted by the unexpected death of his father in 1927, and he was obliged to make the family pharmacy in Manresa his first priority. In his memoirs, he wrote: I couldnt leave the pharmacy and clinical analyses that enabled me to earn a living, nor could I abandon my mother. Thus, the first step was to maintain the prestige that my father had brought to the Plana de lOm pharmacy. The small clinical analysis laboratory that had been installed in the apartment above the pharmacy a few years earlier would soon be used to ...

14 Common Causes of Schwannoma
NF2 stands for neurofibromatosis 2 and is one of the leading causes of schwannomas. In cases of NF2, patients will notice that non-cancerous tumors may develop. These tumors that are caused by NF2 typically grow around the spinal cord and brain. Schwannomas can also develop due to NF2 when tumors grow in the sheath of the nerve. The protective tissues that make up these nerve sheats are actually known as Schwann cells hence the term schwannoma.. The most common type of schwannomas that develop in patients who suffer from NF2 is spinal cord schwannomas. Its essential that you immediately treat schwannomas especially when they are located on the spinal cord as, if they are left untreated, it could lead to paralysis. Early treatment for spinal cord schwannomas is essential to ensuring that no lasting damage occurs. Once paralysis ensues, its very difficult to undo it.. ...
Final Diagnosis -- Case 433
FINAL DIAGNOSIS: INTRAVENTRICULAR SCHWANNOMA (WHO GRADE I).. DISCUSSION:. Schwannomas account for up to 8% of intracranial neoplasms (14). The vast majority of cases arise from the cranial nerves, with the 8th nerve being most commonly involved (14). Rare cases of schwannomas may develop as primarily meningeal, intracerebral or intraventricular tumors (14). In a review of the literature, we found that only few cases of intraventricular Schwann cell tumors have been reported so far (1,4-9,12,13). These tumors were generally located in the lateral or fourth ventricles. To our knowledge, the tumor of our patient is the first reported schwannoma of the third ventricle.. The origin of intraventricular schwannomas is unknown. However, similar to the hypotheses about the histogenesis of spinal intramedullary (3) and intracerebral schwannomas (11), which are slightly more common than intraventricular schwannomas, different possibilities may be considered. Schwannomas may arise from the sympathetic nerve ...
Case Report - E-Discovery Publication
Schwannomas are homogenous tumors of Schwann cells. These cells insulate the peripheral nerves and allow rapid transmission of impulses between CNS and periphery. They produce symptoms by impinging on the nerves. Mostly schwannoma occur in peripheral nerves of head and neck region. Rarely these are seen in the GIT.. The GIT schwannomas have a tendency to ulcerate, bleed, enlarge and cause obstruction. The chance of malignant transformation is 0.3% (2). These tumors also exist with other extra and intra-intestinal tumors; primary adeno-carcinoma of ascending colon (3). An association with Hodgkin Lymphoma and Von Recklinghausen disease was reported by Qasi et al. (2). Despite occurring in the submucosal layer of GI tract they can enlarge up to 120mm in size and cause obstruction (4).. The exact etiology of schwannomas is not known. We hypothesize that chronic irritation of GI lining which leads to stimulation of Schwann cell over growth can contribute to the formation of schwannoma since the ...

intraparenchymal schwannoma [Operative Neurosurgery]
A 39-year-old female had been subject to headache, and intermittent seizures for 9 years and decreasing memory for one year, without obvious neurological signs. An MRI revealed a 2×2 cm contrast-enhanced lesion in the frontal lobe, with a cyst and peritumoral edema, which was not attached to the dura or falx. Preoperatively, it was diagnosed as a glioma. Total surgical removal of the lesion led to a favorable result. Post-operative histo-pathological examination showed characteristic Antoni A and B areas consistent with intraparenchymal schwannoma. Intraparenchymal schwannoma is an extremely uncommon lesion, which is seen mostly in young adults and children. The main clinical symptoms include rising-intracranial-pressure-related manifestations and associated seizure disorders. The possible developmental origins, histological, imaging features, and protocols of treatment for this entity are discussed. ...
SCHWANNOMA PRESENTING AS A GYNAECOLOGICAL MASS WITH PREGNANCY- A CASE REPORT | INTERNATIONAL JOURNAL OF PHARMACEUTICAL SCIENCES...
Abstract Schwannomas are usually benign tumors that result from the proliferation of the perineural cells. Since these tumors are very rare, misdiagnosis is common. Clinically, these tumors may present as a cranial neuropathy, abdominal or soft tissue mass, intracranial lesion, or with spinal cord compression. Histologically, these tumors are encapsulated, highly vascular, and composed of a homogenous pattern of biphasic fusiform-shaped cells that may have a palisaded appearance. We present a case of nineteen years old primigravida with 22 weeks pregnancy with an adnexal mass. The diagnosis of schwannomas was made on laprotomy and confirmed on histopathological examination. The case is reported not only due to its rarity but due to its association with pregnancy and its successful outcome.. ...
