Neurilemmoma is a benign and slowly growing neurogenic tumor. Intrathoracic neurilemmoma often develops in the chest wall and posterior mediastinum, but endobronchial neurilemmoma is extremely rare. The diagnosis of endobronchial neurilemmoma with preoperative imaging findings is challenging and is usually made via postoperative pathological examination. These authors encountered a case of primary endobronchial neurilemmoma in a 52-year-old woman who had no symptoms. A $3.0{\times}2.6$ cm mass in the right lower lobe projecting into the mediobasal segmental bronchus was shown in the results of the contrast-enhanced computed tomography (CT) and magnetic resonance imaging (MRI) of the chest. Benign neurilemmoma was confirmed via bronchoscopic biopsy, and surgical resection (sleeve bronchial excision and end-to-end anastomosis) was performed.

현재 일반적으로 Neurilemmoma 또는 Schwannoma라고 부르는 일련의 종양들은 1908年 Verocay에 의해 처음으로 기술되었으며, 1910년 그는 이것을 "Neurinoma"라고 명명하였다. Neurilemmoma라는 명칭은 1935년 Stoutdp 의하여 처음으로 소개되었다. Neurilemmoma는 신경초(Newe Sheath)를 소유하고 있는 어떤 신경에서나 발생할 수 있는 종양으로서 비교적 희유한 양성종양이며 연령, 성병, 그리고 발생장소에 따른 어떤 우월성은 없었으나 이 종양의 약 25% 이상이 두경부에 발생한다. 다른 부위로 전이를 일으키지 않으며 완전 제거 후에는 재발되지 않으며 방사선에 대한 감수성은 거의 없었다. 저자들은 과거 5년간 본 병원 이비인후과령역에서 수술제거한 5예의 Neurilemmoma를 문헌고찰과 함께 보고하는 바이다.

Neurilemmoma is a benign, well-encapsulated neurogenic tumor that arises in cranial, peripheral, or autonomic nerves that have nerve sheaths containing schwann cells. From 16 to 45% of all neurilemmoma cases occur in the head and neck region and only about 4% of those cases are found in the nose and paranasal sinuses, but very rarely found in the nasal septum. Recently, we experienced a case of isolated neurilemmoma which arose from the nasal septum of a 30-year-old female patient who complained of nasal obstruction and postnasal drip. The mass was broadly based on the right anterior portion of the nasal septum and confined to the nasal cavity, displacing the lateral wall of the nasal cavity and middle turbinate, laterally and posteriorly, respectively. The tumor mass was completely excised through transnasal endoscopic surgery under general anesthesia. The final pathological diagnosis viewed under a microscope after H&E and anti S-100 protein stain was a benign neurilemmoma in which Antoni A type and B type both existed. This report presents a case of neurilemmoma which arose from the nasal septum with reviews of the clinicopathologic features.

Hypoglossal neurilemmoma is extremely rare. Intracranial hypoglossal neurilemmoma has been reported to the present most commonly as a space-occupying lesion with symptoms of raised intracranial pressure. A 68-year-old women presented with deviation of the tongue to the left on protrusion. Preoperative radiological images revealed an extra-axial mass in and around the hypoglossal canal. The tumor was totally resected via retrosigmoid suboccipital approach with burrhole craniectomy. Histopathological examination verified a neurilemmoma. She had no neurologic abnormality except hypoglossal palsy which recovered completely in six months. Retrosigmoid suboccipital approach with burrhole craniectomy can be an useful approach in intracranial hypoglossal neurilemmoma without extracranial extension or with minimal extracranial extension into the hypoglossal canal.

Neurilemmoma is a relatively rare benign tumor which may be derived from nerve sheath of the peripheral, sympathetic and cranial nerve except the optic nerve and olfactory nerve. And it is a characteristically solitary and well-encapsulated mass. About 25% of neurilemmoma occurs in the head and neck region and the acoustic nerve is most frequently involved, but neurilemmoma of the larynx is rare. Recently, we experienced a case of neurilemmoma occurred in the right aryepiglottic fold of the larynx. The tumor was successfully removed by transoral approach under direct laryngoscope. So we report this case with literature review.

기관지내 발생하는 신경초종은 매우 드물며 임상 증상과 방사선적 영상으로 진단하기가 어려워 기관지 내시경을 이용한 생검술이 필요하다. 저자들은 임상적으로 진단하기 어렵고 드문 기관지내 신경초종을 경험하였기에 보고하는 바이다.

Neurilemmomas are benign tumors originating from Schwann cells, and may occur in various nerves; however, they rarely originate from the lingual nerve. When a lingual nerve neurilemmoma develops in the submandibular space, it can be challenging to diagnose it preoperatively, and this tumor can be misdiagnosed as a usual submandibular gland tumor owing to the rarity and a lack of knowledge about lingual nerve neurilemmomas. Therefore, it is important to consider neurilemmoma in the differential diagnosis in cases where the characteristics of the tumor do not correspond with the typical findings of submandibular gland tumors, in order to avoid inadvertent sacrifice of the nerve because of incorrect diagnosis of a salivary gland tumor. Herein, we report a lingual nerve neurilemmoma in the submandibular space, along with a literature review, to highlight the clinical significance and improve understanding of this type of tumor.

Nearly 45% of all neurilemmoma occur in the head and neck area, but only 1% have an intraoral origin. The authors report two cases of uncommon neurilemmoma of the tongue. Both of them presented with a mass on the lateral border of the tongue, which was noted several days before. The lesions of tongue appeared as smooth-surfaced, well-circumscribed mass. They were excised under general anesthesia and diagnosed as neurilemmoma on histopathologic examination.

Neurilemmoma is a benign tumor that originates from the Schwann cell. It frequently occurs in head and neck regions, but neurilemmoma of external auditory canal is extremely rare. Here, we report a very rare case of 36-year-old male with a tumor located in the posterior wall of external auditory canal, preoperatively suspected as neurilemmoma originated from Arnold's nerve by temporal bone magnetic resonance imaging. The tumor mass was surgically excised and pathologically confirmed as a neurilemmoma.
