말초 신경 조직에서 발생되는 종양은 신경섬유종, 신경초종, 파립세포종, 악성신경초종 등이 있다. 신경섬유종은 2가지 형태로 분류될 수 있다. 첫째 형태는 단독형 신경섬유종이고, 둘째는 신경섬유종 혹은 Von Recklinghausen's병으로 불리우는데 이는 주로 피부, 신경조직, 뼈, 연조직에 기형을 유발할 수 있고, 선천적이며, 가족력을 나타낸다. 단독형 신경섬유종은 양성이며, 경계는 명확하나 capsule에 의해 싸여 있지 않으며, 피부나 피하조직에 sessile 혹은 pedunculated 형태로 나타난다. 두경부의 어느 부위에나 나타날 수 있으며, 구강내의 호발 부위는 혀, 협점막, 구개 순이다. 단독형 신경섬유종은 방사선에 의한 치료에 효과가 적으며, 재발율이 낮고, 치료는 주로 외과적 절제술로 제거를 하고, 결손부를 삼각흉피판(D-P flap)과 설피판(tongue flap)으로 수복하여 현재까지 합병증 없이 양호한 결과를 얻었다.

Neurofibroma is a benign, heterogenous peripheral nerve sheath tumor arising from the connective tissue of peripheral nerve sheaths, especially the endoneurium. Its intraoral occurrence is uncommon and its occurrence within mandible is extremely rare. A case of solitary intraosseous neurofibroma of the mandible involving masticator space in a 8-year-old male is reported. He was referred from a private local clinic with a chief complaint of limitation in opening of the mouth. Panoramic and cone-beam computed tomographic images showed unilocular radiolucent lesion with scalloped border at the right mandibular ramus, connected posteriorly to the enlarged mandibular foramen and anteriorly to the mandibular canal. T1-weighted magnetic resonance images showed soft tissue mass of isointensity compared with muscles. Contrast-enhanced T1-weighted images showed peripheral enhancement and T2-weighted images showed the heterogeneous hyperintense mass with extension between lateral and medial pterygoid muscles. The tumor was surgically removed under general anesthesia and diagnosed to be neurofibroma at the biopsy.

Benign neural sheath neoplasms are not common in the maxillofacial region. These lesions can occur as solitary tumors, or they can affect many sites in the form of multiple neurofibromatosis. A solitary neurofibroma is seldom undergo sarcomatous transformation, since solitary neurofibroma is relatively radioresistant and its recurrence rate seems to be low, the treatment of choice is surgical excision. This case showed a solitary neurofibroma in the left side of the floor of mouth which occurred in a 33 - year -old female. The tumor was excised. And there is no evidence of disease. She is satisfied in function and esthetic aspect.

Benign nonepithelial tumors of the thyroid gland are very rare and include lesions such as vascular tumors, smooth muscle tumors and neurogenic tumors. Schwannoma and neurofibroma are benign neoplasms of mesenchymal origin which frequently occur in the head and neck, but their origin within the thyroid gland has rarely been reported. Recently, we encountered two cases of neurogenic tumor of thyroid gland(l schwannoma, 1 neurofibroma) and report them to support the view that Schwannoma and neurofibroma may occur in thyroid gland, which is an unusual site, and are recognizable entities.

The authors have observed a rare case of neurofibroma in 13 years old male who came to the Infirmary of Dental College of Seoul National University because of painless severe swelling of approximately 11 years' duration in the left maxillofacial region and blindness of the left eye about 3 years' duration. As a result of interpretating the serial roentgenograms including tomograms and microscopic findings, we have obtained the following conclusions; 1. Neurofibroma of the patient occurred in about 2 years of age. 2. The familial tendency of the disease has been noted. 3. The growth pattern of the disease was slow, and roentgenographic images revealed severe destruction of bone with irregular borders. 4. The neurofibroma was encapsulated but Verocay body and palisading effect of cells were not seen in the microscopic picture.

Plexiform neurofibroma is a rare benign tumor and a special subtype of neurofibromatosis 1. This report is a literature review with a case of patient with facial hemorrhage observed at the site of neurofibroma removal in the right lower face due to minor trauma. Through PubMed search, using terms ((facial hematoma) OR (facial bleeding)) AND (neurofibromatosis), 86 articles were identified, and five related articles (six patients) were finally selected. Of the six patients, two had previously undergone embolization. However, as a result, all patients received open surgery to remove hematomas. The hemostatic methods mentioned were vascular ligation (five patients), hypotensive anesthesia (two patients), and postoperative blood transfusion (four patients). In conclusion, spontaneous or minimally traumatic bleeding is possible in neurofibromatosis patients. In most cases, it can be resolved by vascular ligation under hypotensive anesthesia. Optionally, prior embolization and supplementary tissue adhesive may be used.

Neurofibroma is characterized as a benign, slow growing neoplasm, originating from Schwann cells or fibroblast in peripheral nerve sheaths. It may appear as a solitary tumor or have multiple localizations in von Recklinghausen disease. They are commonly found in the gastrointestinal tract and laryngeal neurofibromas are extremely rare, accounting for only 0.03 to 0.1% of benign tumors of the larynx. The aryepiglottic fold and arytenoid are the common site of occurrence for laryngeal neurofibroma, because the branch of the superior laryngeal nerve is involved. We present a case of solitary plexiform neurofibroma arising from the laryngeal surface of epiglottis in a 55-year old female who found the lesion incidentally. We removed the tumor completely by transoral laser surgery and no recurrence was found after 7 months. The case of solitary neurofibroma arising from laryngeal surface of epiglottis has not been reported in Korea. We report this case regarding the diagnosis and treatment with review of literatures.

Objective: This study was performed to report the changes in symptoms and radiological consequences of a patient diagnosed with spinal neurofibroma and complaining of lower back pain. Methods: The patient was diagnosed with a spinal neurofibroma after MRI examination and was treated with traditional Korean medicine, including traditional Korean medication and acupuncture. We measured the change in symptom severity using a numerical rating scale (NRS) and the Oswestry Disability Index (ODI). We also used the EQ-5D (EuroQoL-5D) scale to assess the patient's quality of life. In addition, we examined the change in the size of the cyst by MRI twice after discharge: at about 3 months after discharge and at about 8 months after discharge. Results: After about 6 weeks of treatment, most pathological symptoms had decreased. The patient showed a decline in NRS and ODI scores and showed an increase in quality of life. The two MRI examinations after the discharge revealed a decrease in the size of the cyst. Conclusions: Traditional Korean medicine can be a solution for patients with spinal neurofibroma causing neurological pain.

Objectives: The purpose of this study is to report a case of a plexiform neurofibroma (PNF) in the pelvic region treated with sweet bee venom (SBV) and mountain ginseng pharmacopuncture (MGP). Methods: A 16-year-old girl was diagnosed as having PNFs, neurofibromatosis type 1, 10 years ago and she had surgery three times to remove the benign tumors, but the growth of the PNFs continued. She has been treated in our clinic with SBV and MGP two times per month from March 2010 to April 2014. SBV was injected intra-subcutaneously at the borders of the PNFs in the pelvic region, and MGP was administrated intravenously each treatment time. Results: The growths of the PNFs occurred rapidly and continued steadily before treatment. Since March 2010, she has been treated in our clinic, and the growths of the PNFs have almost stopped; further-more, the discomfort of hip joint pain has been reduced, and her general condition has improved. Conclusion: We cautiously conclude that SBV and MGP treatment has some effects that suppress the growth and the spread of the PNFs in this patient.

후두에 발생한 신경성종양은 극히 드물 질환이며 신경초종 혹은 신경섬유종이 나타난다. 현재까지 약 100례 이하의 신경성종양의 보고가 있으며 이들중 신경섬유종양과 동반된 예는 20례에 불과하다. 주 증상으로는 호흡곤란, 발성장애와 언어장애등이 있으며 어느 연령에나 발생할 수 있다. 저자들은 2례의 후두의 신경섬유종을 보고하고자 한다. 증례 1은 선천성후두신경섬유종으로 2개월된 남아는 생후즉시로 부터 심한 호흡곤란과 발성장애가 있었으며, 증례 2는 28세의 여자에서 다발성신경섬유종증(von Recklinghausen's disease)에 동반하여 후두에 신경섬유종이 발생한 예이다. 본 논문에서 자자들은 증례보고와 함께 문헌고찰을 하고자 한다.
