schwannoma septum

Hyun Jin Min, Kyung Soo Kim
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...

We report the case of a 69-year-old woman who was diagnosed with intracardiac schwannoma without symptoms. Preoperative echocardiography and cardiac magnetic resonance imaging showed a mass attached to the interatrial septum. The initial diagnosis was a myxoma or a bronchogenic cyst. The tumor was successfully excised under cardiopulmonary bypass. However, the pathology of the excised tumor was consistent with schwannoma. We suggest that cardiovascular surgeons consider schwannoma to be a possible differential diagnosis for a mass close to the interatrial septum...

Malignant schwannoma is an extremely rare tumor and the risk of malignant schwannoma increases in patients with von Recklinghausen's disease. Recently, we encountered a case of solitary malignant schwannoma in the choana and posterior nasal septum. Malignant schwannoma has not been previously reported in these locations. A 53-year-old man, who was immunologically healthy and showed no abnormal dermatological lesions, presented with a polypoid mass in the right nasal cavity and underwent endoscopic mass excision...

Schwannomas of the nasal cavity and paranasal sinuses are quite rare, especially in the nasal vestibule. We report the case of a 61-year-old woman who presented with a 2-month history of progressively worsening right-sided epistaxis and nasal blockage. Rigid nasoendoscopy showed a mobile, smooth, globular mass occupying the right nasal vestibule. The mass arose from the lateral nasal wall and impinged on the anterior part of the middle turbinate posteriorly. Computed tomography of the paranasal sinuses showed a 3...

Schwannomas of the head and neck are the most common form of benign nerve sheath tumours, most commonly arising in the form of vestibular schwannomas. Schwannoma of the nasal cavity is an uncommon presentation of this pathology and specifically Schwannoma of the nasal septum is a rare presentation of this well understood disease process. We present the case of a 31-year-old Eastern European male who presented with unilateral nasal obstruction, congestion and epistaxis of 3 months duration. After imaging and biopsy, the diagnosis of nasal septal schwannoma was made on histological examination...

A schwannoma is a rare benign tumour of peripheral nerve origin. We present a case of a 65-year-old woman with a 1-year history of a slowly enlarging, painless and movable mass, palpable by fingers in her right lower eyelid, adjacent to the inferior orbital rim. No apparent mass was present by macroscopic examination. A subciliary incision and blunt dissection through the septum revealed a pearl-like round and encapsulated cystic mass between the fat pads just below the septum. A total excision of the tumour was performed...

INTRODUCTION: Gastrointestinal stromal tumors are very rare, representing 0.1% to 1% of gastrointestinal malignancies. Gastrointestinal stromal tumors outside the digestive tract comprise a very small fraction of all gastrointestinal stromal tumors, and their most common locations are the omentum, the mesentery, and, in few cases, the rectovaginal septum. Despite their low incidence, extragastrointestinal stromal tumors are potentially malignant tumors and they present a high rate of recurrences...

Schwannomas of the nasal cavity are rare benign tumors, and those that arise from the nasal septum are even rarer. When they do occur, they usually become symptomatic early because of the close confines of the nasal cavity. We describe a case of nasal septal schwannoma that was noteworthy in that the patient-a 28-year-old woman-waited 8 months after the onset of symptoms to seek medical care. Her symptoms included complete right-sided nasal obstruction, occasional epistaxis, and hemifacial pain. The tumor was completely removed via an endoscopic approach...

Schwannoma of nasal septum presentation is exceedingly rare in the literature, previously reported multiple lesions involving the paranasal sinuses or nasal mucosa. We report the case of a 20 year-old yellow male with a tiny schwannoma arising from the nasal septum, complaining of lightly alternate nasal obstruction. Both anterior and endo-rhinoscopy didn't detect this tiny smooth-surfaced mass and other abnormality, except a little septal deviation. After final clinical diagnosis, we completely removed this tumor and corrected the deviation by an endoscopic approach...

A primary benign schwannoma of the liver is extremely rare and is difficult to preoperatively discriminate from a malignant tumor. We compared the imaging and pathological findings, and examined the possibility of preoperatively diagnosing a benign liver schwannoma. A 72-year-old woman was admitted to our hospital because of a 4.6-cm mass in the liver. A malignant tumor was suspected, and a right hepatectomy was performed. After this, the diagnosis of a primary benign schwannoma of the liver was made through pathological examination...

BACKGROUND: Transnasal approaches to the anterolateral maxillary sinus and infratemporal fossa are challenging with traditional endoscopic techniques and instrumentation. Additional access in the anterior and lateral direction can be obtained with modified endoscopic medial maxillectomy (MEMM) or total endoscopic medial maxillectomy (TEMM) or via a transseptal approach. Alternatively, we have used a septal dislocation technique to help access these areas. Access to these areas may be necessary for treatment of inverted papilloma, schwannoma, and juvenile nasopharyngeal angiofibromas...
