schwannoma septum

INDICATIONS CORRIDOR AND LIMITS OF EXPOSURE: The major indications of endoscopic transorbital approach include spheno-orbital meningiomas, cavernous sinus lesions, and Meckel cave lesion such as trigeminal schwannomas. It can avoid excessive brain retraction and allows for a fast recovery to the normal daily living activity. ANATOMIC ESSENTIALS NEED FOR PREOPERATIVE PLANNING AND ASSESSMENT: To access the cavernous sinus, the sagittal crest and meningo-orbital band should be identified and cut...

Schwannoma is a rare benign neurogenic tumor arising from the Schwann cells of peripheral nerves. A 77-year-old man presented with progressively worsening left nasal block and hyposmia for the past six months. Nasal endoscopy revealed a polypoidal reddish mass occupying the left middle meatus. The biopsy was in favor of ancient schwannoma. Endoscopic transnasal excision of the mass arising from the left nasal septum was performed. A middle meatal antrostomy was also performed. The tumor cells were positive for S100 protein...

Schwannomas are the most common type of benign peripheral nerve tumor in adults. Schwann cells assist in the conduction of nerve impulses and wrap around peripheral nerves to provide protection and support. Schwannomas typically arise from a single fascicle within the main nerve. Although they can occur anywhere in the body, nasal schwannomas are exceptionally rare. This case study presents a 65-year-old Caucasian female who had been experiencing obstructive nasal symptoms for three months. The in-office physical examination revealed a soft tissue expansile mass involving the submucosal tissues of the bilateral anterior nasal cavity, located just posterior to the columella...

Schwannomas of sinonasal origin are rare tumours with an incidence as low as 4% and may present with a wide range of clinical features. Due to non-specific endoscopic and radiological findings, diagnosis becomes difficult. We present a case of an ethmoidal schwannoma with nasal and nasopharyngeal extension in an elderly female patient who had a slow course of the long-standing disease. Her main complaints were nasal obstruction, nasal discharge, mouth breathing, snoring and recurrent nasal bleed. Nasal endoscopy showed a pale, firm, polypoidal mass with dilated vessels on the surface which bled on probing...

Schwannomas of the sinonasal compartment are rare benign neoplasms of peripheral nerve sheath origin and constitute ~ 4% of all head and neck schwannomas. The presentation may simulate a range of benign and intermediate grade pathologies. Management involves surgical excision via open or endoscopic approach. To describe the clinico-epidemiological characteristics and surgical outcomes in sinonasal region schwannoma patients operated at our institute. The study is a descriptive case series of patients with sinonasal region schwannomas treated at our institution...

INTRODUCTION AND IMPORTANCE: Ewing sarcomas are a group of small round cell tumors that occur predominantly in the long bones as well as in extraosseous locations such as the extremities, trunk, and retroperitoneum (Gier, 1997) [2]. Extraosseous Ewing sarcoma (EES) is a type of small round cell tumor that occurs in soft tissues. I rare cases, EES occurs in the esophagus (Maesawa et al., 2002; Johnson et al., 2010) [1,3]. Ewing's sarcoma is a rare and highly aggressive cancer most frequently arising in people under 20 years of age...

Schwannomas are rare slow-growing benign tumors arising from Schwann cells lining the nerve sheaths. Head and neck schwannomas account for about one-third of all cases, and only 4% of them arise from the sinonasal tract. Its diagnosis is based on histology and immunohistochemistry. Complete surgical excision is the most recommended treatment option, and endoscopic surgery has been widely performed in recent years. In this study, we presented a case of a 55-year-old female with schwannoma arising from the lateral wall of the nasal cavity, causing epistaxis and rhinorrhea...

Schwannomas, which originate from Schwann cells in the peripheral nervous system, are slowgrowing and uncommon benign tumors. Most schwannomas (90%) occur in isolation, and multiple occurrences are a characteristic feature of neurofibromas. Schwannomas of the nose and nasal tip are particularly unusual. Although a few cases of schwannomas of the sinusoidal tract and nasal septum have been reported, schwannomas arising from the nasal dorsum area and tip are extremely rare. Sensory abnormalities are also a very rare symptom...

INTRODUCTION: Sinonasal schwannoma accounts for only 4% of head and neck nerve sheath tumors. Schwannoma of the nasal septum is still the rarest, with only few cases previously reported. CASE PRESENTATION: This study presents the case of a 64-year-old Saudi female of the Eastern Province who presented a several-month history of unilateral progressive nasal obstruction and recurrent episodes of epistaxis. The diagnosis of nasal septal schwannoma was made on the basis of a histopathological examination...

Schwannoma is a slow-growing, benign tumor of the nerve sheath. It rarely presents in the nasal cavity or the paranasal sinuses. Although schwannomas in the nasal septum have been reported previously, cases of this tumor in the nasal columella are rare in the literature. Here, we report on a 67-year-old woman with a schwannoma in the nasal columella that was successfully removed using a sublabial approach, along with a review of relevant literature.

Sinonasal schwannomas constitute 4% of head and neck nerve sheath tumours; however, schwannomas involving the nasal septum are quite rare. We present a 57-year-old male patient with nasal septal schwannoma who was managed successfully by endoscopic excision. 32 cases of septal schwannoma have been reported so far in the literature. This report discusses certain peculiar features exhibited by schwannomas of the nasal septum. Septal schwannoma does not show any age, sex or side predilection. However, they tend to involve posterior part of the septum and presumed to arise from the nasopalatine branch of the trigeminal nerve...

A schwannoma is a benign tumor arising from Schwann cells present in the nerve sheath of myelinated nerves.It is rarely seen in the nose and paranasal sinuses, and it very rarely originates from the nasal septum. A 40-year-old female presented to our outpatient department with a gradual onset, progressive, left nasal obstruction since the last 4 years. On performing a local examination, a soft tissue mass occupying the left nasal cavity was seen. Surgery via the external approach was performed; the mass was found to arise from the nasal septum and was totally excised...

Schwannoma is an uncommon tumor of nerve sheath that arises from any peripheral, cranial, or autonomic nerve. Only 4% of head and neck schwannomas originate from the sinonasal tract, and a finding of a schwannoma in the nasal septum is exceedingly rare. The authors experienced nasal septal schwannoma with the functional and aesthetic consideration of nasal contour. The authors present an open rhinoplasty approach for nasal septal schwannoma which has not been reported in the previous literature yet.

Recently, as the authors experienced nasal septal schwannoma and nasal septal neurofibroma with similar clinical symptoms but different endoscopic findings, the authors tried to review all the literatures previously reported on the "Nasal septal schwannoma and Nasal septal neurofibroma." The aim of this study is to thoroughly review previously reported patients with nasal septal schwannomas and neurofibromas and to describe similar and different features focusing on the differential diagnosis between the 2 entities...

An asymptomatic pancreatic tumor was discovered in a 77-year-old man during a medical check-up. An abdominal computed tomography (CT) and magnetic resonance imaging (MRI) revealed a cystic mass containing a septum-like solid portion in the head of the pancreas, measuring 3.5cm in diameter. Additionally, abdominal contrast-enhanced ultrasonography (US) revealed increased flow in the solid portion and a tumor capsule in its early phase. We preoperatively diagnosed the lesion as a cystic-degenerated pancreatic neuroendocrine tumor or solid-pseudopapillary tumor and performed a pancreatoduodenectomy...

The nasal septum is one of the rarest sites of origin of schwannomas. Recently, as the authors experienced a patient with nasal septal schwannoma completely removed by transnasal endoscopic approach, the authors tried to review all the literatures reported since Berlucchi's report in 2000. To the best of our knowledge, only 18 patients with nasal septal schwannoma in the literatures written by English-language have been reported. The purpose of this study is to describe our recent experience and thoroughly review our collected patients with nasal septal schwannoma with particular emphasis on therapeutic options...

Schwannomas are benign tumors deriving from Schwann cells of the nerve sheath. They can occur in all parts of the body. Involvement of the nasal septum is quite rare, with only few cases having been reported in the literature. The authors present a patient with a unilateral tumor diagnosed as a schwannoma of the nasal septum.

PROBLEM: Schwannomas (neurilemmomas) are benign primary tumours that arise from Schwann cells. Schwannomas arising from the nasal septum are exceptionally rare. Here, we report a unique case of schwannoma of the nasal septum presenting as a multicentric neuronal tumour. RESULTS: A 40-year old male sustained intermittent left tinnitus. Magnetic resonance imaging revealed masses near the nasal septum and upper cervical cord in addition to a tumour in the left cerebellopontine (CP) angle...

We report herein a case of benign cardiac schwannoma in the interatrial septum. A 42-year-old woman was transferred from a clinic because of cardiomegaly as determined by chest X-ray. A transthoracic echocardiography and chest computed tomography examination revealed a huge mass in the pericardium compressing the right atrium, superior vena cava (SVC), left atrium, and superior pulmonary vein. To confirm that the tumor originated from either heart or mediastinum, cine magnetic resonance imaging was performed, but the result was not conclusive...

BACKGROUND: Sinonasal schwannoma (SNS) is a rare sinonasal tract tumor whose presentation is similar to that of other benign nasal tumors. Very few case series appear in the literature. This study aims to describe the presentation, treatment, and outcome of 10 SNS cases from 3 referral centers. METHODS: All SNS cases were analyzed retrospectively. Patient demographics, tumor data, surgical procedures, and outcome were recorded. RESULTS: Five males and 5 females (mean age, 49...
