  • [Title] Ancient schwannoma arising from mental nerve. A case report and review.
  • Schwannoma is an intraoral rare, benign neoplasm derived from the nerve sheath of peripheral nerves.
  • "Ancient schwannoma" shows histopathological features, such as degenerative changes and atypical nuclei, and may easily be confused with malignant neoplasms.
  • Ancient schwannoma of the head and neck region is relatively uncommon and very few cases had been reported in the oral cavity.
  • We present a case of ancient schwannoma arising from the mental nerve in a 19 year old male which was of eight months duration.
  • Ultrasonography showed that the tumor was closely associated with the mental nerve on the left side, suggestive of a peripheral neural sheath tumor.
  • The histological picture was strongly suggestive of ancient schwannoma (Antoni A type).

2. Chan PT, Tripathi S, Low SE, Robinson LQ: Case report--ancient schwannoma of the scrotum. BMC Urol; 2007;7:1
Genetic Alliance. consumer health - Schwannoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Case report--ancient schwannoma of the scrotum.
  • BACKGROUND: Scrotal schwannoma is a rare neoplasm and poses a diagnostic challenge to urologists.
  • This article describes a rare case of ancient scrotal schwannoma and reviews the current modality of investigation and treatment of this tumour.
  • Surgical excision was undertaken and histology was an ancient schwannoma of the scrotum.
  • CONCLUSION: Schwannoma is a benign encapsulating neoplasm with an overall low incidence, occurring mostly in the head and neck region and seldom in the scrotum.
  • Histology shows two distinctive patterns, Antoni type A and B areas.
  • Variations of schwannoma such as cellular, ancient, glandular and epithelioid are observed based on the appearances.
  • Ancient schwannoma exhibits pleomorphism without mitosis as the result of cellular degeneration, which can lead to an erroneous diagnosis of malignancy.
  • Imaging modalities are non-specific for schwannomas, but can define tumour size, site and extension.

Genetic Alliance. consumer health - Schwannoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Ancient schwannoma of the conus medullaris.
  • Cystic spinal or ancient schwannoma is a rare form of intradural tumour especially in the conus medullaris region.
  • Due to its indolent behavior and benign course, the diagnosis of schwannoma is always a challenge and the imaging findings can be misleading.
  • MRI of the spine showed intradural tumour located at the conus medullaris region with nerves compression and was reported as ependymoma.
  • L3-L5 laminectomy and total excision of tumour was performed without any neurological complication.
  • We concluded that ancient schwannoma of the conus medullaris is a rare benign tumour that can present with minimal non-specific neurological symptom that lead to misdiagnosis.
  • Radical tumour excision is safe with an excellent outcome.

7. Bhatia RK, Banerjea A, Ram M, Lovett BE: Benign ancient schwannoma of the abdominal wall: an unwanted birthday present. BMC Surg; 2010;10:1
Genetic Alliance. consumer health - Schwannoma.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Benign ancient schwannoma of the abdominal wall: an unwanted birthday present.
  • BACKGROUND: There has been a recent growth in the use of whole body Computerised Tomography (CT) scans in the private sector as a screening test for asymptomatic disease.
  • There has been concern raised over the possible harms of the test in terms of radiation exposure as well as the risk and anxiety of further investigation and treatment for the large numbers of benign lesions identified.
  • Histology demonstrated this to be a benign ancient schwannoma and we believe this to be the first reported case of an abdominal wall schwannoma in the English literature CONCLUSIONS: Ancient schwannomas are rare tumours of the peripheral nerve sheaths more usually found in the head, neck and flexor surfaces of extremities.
  • They are a subtype of classical schwannomas with a predominance of degenerative changes.
  • Our case highlights the pitfalls of such screening tests in demonstrating benign disease and subjecting patients to what turns out to be unnecessary invasive investigation and treatment.
  • Should the number of scans increase there may be an unnecessary burden on NHS resources due to the large numbers of benign lesions picked up, that are then referred for further investigation.

  • [Title] Whole-body MRI evaluation of tumor burden in the neurofibromatosis tumor suppressor syndromes.
  • : 2074 Background: Neurofibromatosis 1 (NF1), NF2, and schwannomatosis are a group of related genetic disorders in which affected individuals share the predisposition to develop multiple neurofibromas and schwannomas.
  • The number and type of tumors (discrete vs. plexiform) were identified by a board-certified radiologist and tumor volume was calculated using semi-automated analysis.
  • Sixty-one percent of subjects had ≥1 internal tumor.
  • Only 40% of internal tumors were classified as plexiform yet these tumors contributed 78% of the tumor burden by volume.
  • In addition, WBMRI may prove useful in identifying individual patients at high risk for complications (such as neurologic dysfunction or malignant transformation) due to heavy internal tumor burden and in determining the efficacy of antitumor drugs in this unique patient population.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Increased preservation of functional hearing after gamma knife surgery for vestibular schwannoma.
  • OBJECT: Gamma knife surgery (GKS) for vestibular schwannoma is still associated with an additional hearing loss of approximately 30%.
  • METHODS: Seventy-eight of 95 patients who entered a prospective protocol with a follow up of at least 12 months (mean 22 months) were evaluated.
  • The mean tumor volume was 2.28 cm<sup>3</sup>.
  • After a mean follow-up duration of 22 months, the magnetic resonance imaging-based tumor control rate was 87%.
  • CONCLUSIONS: Reducing the maximum dose to 20 Gy seems to be an effective treatment, which probably increases preservation of functional hearing without sacrificing the high tumor control rates achieved in radiosurgery.
  • Post-radiosurgery tumor swelling occurred in 25% of the cases and was not correlated with hearing deterioration.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Ancient schwannoma of the vulva.
  • BACKGROUND: Ancient schwannoma, a variant of schwannoma (previously termed neurilemoma), arises from the Schwann cells of the nerve sheath.
  • The tumor was slowly increasing in size and affected activities such as sitting and walking.
  • Surgical excision was undertaken, and histology demonstrated an ancient schwannoma.
  • CONCLUSION: The characteristic histological appearance seen in ancient schwannoma should prevent the erroneous diagnosis of a malignant tumor.

  • [Title] A rare retroperitoneal schwannoma in a patient with neurofibromatosis Type 2.
  • Neurofibromatosis Type 2 (NF2) is a dominantly inherited tumour-prone disorder, characterized by the development of multiple schwannomas, meningiomas and ependymomas.
  • Vestibular schwannoma (VS) is the hallmark of NF2.
  • Retroperitoneal schwannomas are expected to occur in only 3% of cases.
  • We present the case of a large retroperitoneal schwannoma in a patient with NF2.
  • Brain, orbits, cervical, thoracic and lumbar MRI revealed bilateral VS, multiple meningiomas as well as multiple schwannomas and ependymomas in the cervical, thoracic and lumbar spine.
  • The retroperitoneal mass represents a schwannoma probably derived from an intercostal nerve.

  • [Title] Ancient schwannoma of the oesophagus presenting with stridor: case report.
  • OBJECTIVE: We report a rare presentation of ancient schwannoma of the oesophagus, management of which required tracheal resection.
  • She had undergone laser excision of a tracheal tumour thrice in the past.
  • Fibre-optic bronchoscopy showed a tumour arising from the posterior wall of the trachea.
  • Histopathology was typical of an ancient schwannoma.
  • CONCLUSION: This case emphasises the need to consider oesophageal schwannomas in the differential diagnosis of posterior tracheal tumours; it also highlights the need for careful pre-operative assessment in the management of these tumours in order to avoid complications.

  • Schwannomas are benign tumors that arise from neural sheath Schwann cells.
  • Solitary benign schwannomas are generally located in the head and neck, often along the cranial nerves, and are a particularly rare neoplasm among tumors of the retroperitoneal space.
  • The pathological diagnosis was retroperitoneal benign schwannoma consisting of mixture of a Antoni-A and -B type cells.
  • We report a case of retroperitoneal schwannoma and discuss eleven previous reports treated by laparoscopic surgery in the English literature.
  • Laparoscopic resection may be useful because a retroperitoneal schwannoma, which is commonly localized and hypovascular, can easily be dissected from the adjacent tissues.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Intramedullary schwannoma with calcification of the epiconus.
  • BACKGROUND CONTEXT: There have been few reports on intramedullary ancient schwannoma.
  • Schwann cells are generally present in the nerve root, not in the spinal cord.
  • Thus, intramedullary schwannomas are rare, and in most cases there is cyst formation without calcification.
  • PURPOSE: To report a patient with intramedullary ancient schwannoma at the epiconus together with a review of the previously published cases.
  • Magnetic resonance imaging showed a tumorous mass in the intramedullary region of epiconus at T11-L1, and computed tomography revealed calcification in the tumor.
  • She underwent total resection of the tumor.
  • Histopathological findings were consistent with the diagnosis of ancient schwannoma.
  • CONCLUSION: We reported a rare case presenting epiconus syndrome due to intramedullary ancient schwannoma, which should be considered for the differential diagnosis of a tumor that shows calcification.

  • BACKGROUND: Ancient schwannomas are degenerate peripheral nerve sheath tumors that very rarely occur in the retroperitoneum.
  • We describe three cases of retroperitoneal ancient schwannomas and discuss the diagnosis and management of these tumors.
  • CASE PRESENTATIONS: Three female patients with retroperitoneal ancient schwannomas were reviewed.
  • Histological examination showed encapsulated tumors that displayed alternating areas of dense cellularity and areas of myxoid matrix consistent with a diagnosis of ancient schwannoma.
  • CONCLUSION: A diagnosis of ancient schwannoma should be entertained for any heterogeneous, well encapsulated mass in the retroperitoneum.

  • [Title] Plexiform pigmented schwannoma of the uvea.
  • Schwannoma is a slow growing solitary tumor that preferentially involves spinal nerve roots, and sympathetic, cervical, and vagus nerves.
  • There are several clinico-pathologic variants of schwannoma, including schwannoma with a degenerative change (ancient schwannoma), cellular schwannoma, plexiform schwannoma, epithelioid schwannoma, and melanotic schwannoma.
  • About 10% of cases of schwannomas are associated with multi-system disorders such as neurofibromatosis, schwannomatosis, multiple meningiomas, and Carney complex.
  • Schwannoma rarely present as an intraocular tumor and is often misdiagnosed as malignant melanoma.
  • In this article, we review the clinical and histopathological findings of a sporadic plexiform pigmented schwannoma involving the iris, ciliary body, and the choroid.

  • We report a case of a 28-year-old woman who presented with a pelvic mass and obscure clinical signs.
  • Imaging methods suggested that this tumor was most probably an ovarian mass of embryonic origin.
  • After dissection by laparotomy, the microscopic examination showed typical futures of a neurilemoma (ancient schwannoma).
  • The goal of the operating intervention is to excise the tumor avoiding major trauma, thus cooperation between surgeons is indispensable.

  • The tumor measured 210 mm at its largest diameter and was ulcerated, hemorrhagic, multilocular and non-mobile.
  • It should be noted that the patient stubbornly refused to see a doctor for a long time, resulting in the extreme growth of the tumor.
  • Dermatohistopathological findings of the biopsy indicated ancient schwannoma and total excision was therefore performed.
  • Post-mortem skin biopsy revealed features of malignant peripheral nerve sheath tumor.
  • We propose that the expressions of Ki67 and p16 should be checked for all lesions of peripheral nerve sheath tumor for distinguishing benign from malignant forms.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Long-term results of Leksell gamma knife surgery for trigeminal schwannomas.
  • OBJECT: The authors evaluated the long-term efficacy of gamma knife surgery (GKS) in patients with trigeminal schwannomas.
  • METHODS: Fifty-six patients, 31 women and 25 men (mean age 42 years), underwent GKS for trigeminal schwannomas.
  • The mean target volume was 8.7 cm<sup>3</sup> (range 0.8-33 cm<sup>3</sup>); the mean maximum dose was 27 Gy (range 20-40 Gy); the mean tumor margin dose was 13.3 Gy (range 10-15 Gy); and the mean follow-up period was 68 months (range 27-114 months).
  • Disappearance of the tumor occurred in seven patients.
  • An obvious decrease in tumor volume was observed in 41 patients, four tumors remained unchanged, and four tumors progressed at 5, 26, 30, and 60 months, respectively.
  • One patient with disease progression died of tumor progression at 36 months after GKS.
  • The tumor growth control rate in this group was 93% (52 of 56 cases).
  • Four patients experienced mild symptom deterioration related to tumor progression.
  • CONCLUSIONS: Radiosurgery proved to be an effective treatment for small- and medium-sized trigeminal schwannomas.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Tumour and tumour-like conditions of peripheral nerve origin: ten years' experience.
  • BACKGROUND: There are four major lesions which may arise in the peripheral nerve, namely neuroma, schwannoma, neurofibroma and malignant peripheral nerve sheath tumor.
  • Among the nonmalignant cases neurofibroma was the commonest (51 cases, 45% of all) closely followed by schwannoma (39 cases, 34% of all).
  • Among the schwannoma cases 4 were diagnosed as ancient schwannoma with presence of bizarre cells with hyperchromatic nuclei.
  • The commonest site involved for both schwannoma and neurofibroma was scalp-face-neck followed by back.
  • The age range for schwannoma was 16 to 75 years whereas the same for the neurofibroma cases was 2 to 82 years.
  • CONCLUSION: The majority of the tumor are benign and the commonest benign tumor was neurofibroma of sporadic type, closely followed by schwannoma.

  • [Title] Hybrid schwannoma/perineurioma: clinicopathologic analysis of 42 distinctive benign nerve sheath tumors.
  • Benign nerve sheath tumors include neurofibromas, schwannomas, and perineuriomas.
  • We have recently recognized tumors showing hybrid features of schwannoma and soft tissue perineurioma.
  • Tumor size ranged from 0.7 to 17.5 cm (mean, 3 cm).
  • Histologically, the tumors were usually well circumscribed but unencapsulated, and composed of spindle cells with plump, tapering nuclei, and palely eosinophilic cytoplasm with indistinct cell borders, arranged in a storiform, whorled, and/or lamellar architecture.
  • Only 1 tumor showed infiltrative margins.
  • One tumor showed a plexiform growth pattern.
  • Antoni A and B zonation and hyaline vessels were absent.
  • Most tumors were composed of approximately 60% to 70% of Schwann cells and 30% to 40% of perineurial cells.
  • After a mean follow-up of 24 months (range, 6 to 60 mo), 1 tumor recurred locally, after incomplete excision.
  • Benign nerve sheath tumors showing predominantly schwannian cytomorphology and perineurioma-like architecture are composed of an admixture of both cell types.
  • Degenerative nuclear atypia (akin to that seen in ancient schwannoma and atypical neurofibroma) is relatively common.
  • Hybrid schwannoma/perineuriomas have no evident association with neurofibromatosis and rarely recur.

  • Ancient schwannomas are rare, encapsulated tumours of long duration and are benign in nature.
  • The tumour is solitary and may grow to a large size before detection of notable degenerative changes.
  • The term "ancient schwannoma" is used to describe a tumour that has undergone such changes, typified by relative loss of Antoni type A tissue, perivascular hyalinisation, calcification, cystic necrosis, haemorrhage and the presence of degenerative nuclei that may be misinterpreted as sarcomatous pleomorphism.
  • We report two cases of ancient schwannoma in the thigh mimicking malignancies.
  • Identifying the fibrous capsule of the mass and a split fat sign using MRI is important for differentiating ancient schwannoma from other malignant tumours.

  • [Title] Ancient schwannoma of the female pelvis.
  • BACKGROUND: The objective of this article is to define the imaging characteristics of ancient schwannoma, which is a rare variant of benign schwannoma with degenerative changes, arising in the female pelvis simulating ovarian tumors.
  • METHODS: Eleven surgically proven ancient schwannomas of the female pelvis were evaluated retrospectively on the basis of CT and MR findings.
  • RESULTS: Typical intra-pelvic schwannoma was a neurologically asymptomatic large mass, which may situate at presacral or lateral pelvic region with the continuity to the nerve or neural foramen.
  • Ancient schwannomas manifested as encapsulated solid masses with random or eccentric cystic areas, or as cystic masses with marginal crescent-shaped or nodular solid components.
  • To detect ipsilateral normal ovary and to demonstrate centripetal displacement of the adjacent rectum or iliac vessels were helpful to diagnose the tumor as an extra-ovarian mass situated at the extraperitoneal region.
  • CONCLUSIONS: Diagnosis of ancient schwannoma before surgical treatment is important and should be made by its characteristic clinical and imaging findings.

  • [Title] Gamma knife surgery for vestibular schwannoma: 10-year experience of 195 cases.
  • OBJECT: The authors conducted a study to determine the optimal radiation dose for vestibular schwannoma (VS) and to examine the histopathology in cases of treatment failure for better understanding of the effects of irradiation.
  • Seventy-two patients (37%) had undergone partial or total excision of their tumor prior to gamma knife surgery (GKS).
  • The mean tumor volume was 4.1 cm<sup>3</sup> (range 0.04-23.1 cm<sup>3</sup>).
  • Multiisocenter dose planning placed a prescription dose of 11 to 18.2 Gy on the 50 to 94% isodose located at the tumor margin.
  • At the latest MR imaging assessment decreased or stable tumor volume was demonstrated in 93.6% of the patients.
  • Uncontrolled tumor swelling was noted in five patients at 3.5, 17, 24, 33, and 62 months after GKS, respectively.
  • Histopathological examination of specimens in three cases (one at 62 months after GKS) revealed a long-lasting radiation effect on vessels inside the tumor.
  • A margin 12-Gy dose with homogeneous distribution is effective in preventing tumor progression, while posing no serious threat to normal cranial nerve function.

  • Ancient change in a schwannoma is a histological variant typically found in longstanding tumors.
  • Histologically, the tumor has biphasic features typical of a schwannoma with evidence of degenerative changes that may complicate diagnosis.
  • The authors report on a 23-year-old man with no features of neurofibromatosis who presented with headaches, blurred vision, and ataxic gait.
  • At surgery, the tumor was found to arise from the inferior division of the trigeminal nerve.
  • The final histological diagnosis was schwannoma with ancient change.
  • Note that ancient change in schwannomas is a histological variant thought to result from degenerative changes in longstanding tumors.
  • To the authors' knowledge, this is the first independent report of this histological variant in an intracranial schwannoma.

  • OBJECTIVES: We report one case of retroperitoneal schwannoma with unfrequent histological characteristics evaluating its clinical significance and therapeutic options.
  • METHODS: We report the case of a benign retroperitoneal schwannoma as an incidental MRI finding in a 70 year-old female patient with symptoms of lumbosciatic pain for 6 months.
  • RESULTS: After surgical excision the diagnosis was retroperitoneal old schwannoma.
  • The histological changes apparent in the cases of old schwannoma have been interpreted as degenerative, indicating a long evolution, which has motivated its denomination as old.
  • CONCLUSIONS: The old schwannoma is a rare variety of the benign common schwannoma.
  • Therapeutic management is similar to other benign retroperitoneal processes, surgical excision and follow-up.

  • [Title] [Subfrontal schwannoma: case report].
  • Schwannoma are benign, slowly growing nerve sheath tumors.
  • They can arise from any peripheral nerve containing Schwann cells including distal portions of cranial nerves.
  • Intracranial schwannomas arising from a subfrontal lesion are very rare.
  • We report a case of subfrontal schwannoma in a 38-year-old woman who presented with seizures in February 2003.
  • The left carotid angiography revealed that the tumor was supplied from the anterior ethomoidal artery, but no remarkable tumor stain was detected.
  • Bifrontal craniotomy with total excision of the tumor revealed a tumor in the left subfrontal lesion.
  • The tumor was attached to the falx, the left frontal lobe, and the skull base, but those structures were not invaded.
  • Subsequent histological examination proved that this tumor was schwannoma.
  • Arguments are raised that schwannomas in a subfrontal lesion are comparable to or even occur as intracranial schwannomas with frontal localization.
  • Subfrontal schwannomas are very rare.
  • Further cases of subfrontal schwannoma are necessary to solve the enigma of the origin of this tumor.

  • [Title] Schwannoma of the auricle.
  • OBJECTIVES: We report an extremely rare case of schwannoma of the auricle.
  • METHODOLOGY: A case report and review of the world literature concerning schwannoma of the auricle are presented.
  • RESULTS: Schwannoma is a benign, encapsulated, slow-growing neoplasm.
  • Approximately 25-45% of all schwannomas occur in the head and neck, whereas schwannomas of the external ear are extremely uncommon, with only nine cases reported in the English literature since the first report in 1977.
  • In this report, we describe the case of a 47-year-old male patient who presented with a 2-year history of a slow-growing mass in the left auricle, which was managed by wide surgical excision.
  • We believe this case to be the second case of schwannoma of the auricle reported.
  • CONCLUSIONS: To our knowledge, this is the second report in the world literature of auricle schwannoma.
  • Schwannoma should be considered in the evaluation of any tumour of the auricle.

  • [Source] The source of this record is MEDLINE®, a database of the U.S. National Library of Medicine.
  • [Title] Melanotic schwannoma.
  • BACKGROUND: Melanotic schwannomas are tumors of Schwann cell origin, characterized by cytoplasmic deposition of melanin.
  • Melanotic schwannomas are rare.
  • Description of the course of these tumors differs somewhat, but it is generally considered a benign lesion.
  • A diagnosis of melanotic schwannoma was made based on histologic morphology and the immunohistochemical profile.
  • CONCLUSION: Melanotic schwannoma is a rare variant of schwannoma composed of melanin-producing cells with ultrastructural features of Schwann cells.
  • Distinguishing between this tumor and malignant melanoma is important in planning management.
  • Appropriate long-term follow-up is needed for all melanotic schwannomas.

  • INTRODUCTION: Schwannomas are tumors charasteristically originated from the nerve sheath.
  • They expande eccentrically from the nerve promoting a disturbance in the neural function either due to vascular compresion or to the effect of the tumor itself on the nerve, disturbance that can be evidenced with the Auditory-evoked Brainstem Response (ABR), fact that constituted the base for their diagnosis in the past.
  • OBJECTIVE: To describe the most frequent ABR patterns in those patients suffering from acoustic schwannoma related to the size of the tumour and the remanent audition thresholds, and to determine the value of this test in our practice.
  • Whose diagnosis was done between 1997 and 2003 in relation to the size of the tumour and the residual auditory function.
  • RESULTS AND CONCLUSIONS: ABR has a good sensibility for detection of acoustic schwannoma.
  • ABR patterns do not relate to the size of the tumour but they do to the auditory function.
