Objective : This is a retrospective review of 22 surgically treated benign and malignant tumors of brachial plexus region to describe clinical presentation, the characteristics of brachial plexus tumor and clinical outcomes with a literature review. Methods : Twenty-one patients with consecutive 22 surgeries for primary brachial plexus tumors were enrolled between February 2002 and November 2011 were included in this study. The medical records of all patients were reviewed. Results : Eleven male and 10 female patients were enrolled. Mean age was 39 years. Three patients had brachial plexus tumor associated with neurofibromatosis (13.6%). Presenting signs and symptoms included parenthesis and numbness (54.5%), radiating pain (22.7%), direct tenderness and pain (27.2%), palpable mass (77.3%). Twelve patients presented preoperative sensory deficit (54.5%) and 9 patients presented preoperative motor deficit (40.9%). Twenty tumors (90.9%) were benign and 2 tumors (9.1%) were malignant. Benign tumors included 15 schwannomas (68.2%), 4 neurofibromas (18.2%) and 1 granular cell tumor (4.5%). There were 1 malignant peripheral nerve sheath tumor (MPNST) and 1 malignant granular cell tumor. Gross total resection was achieved in 16 patients (72.7%), including all schwannomas, 1 neurofibroma. Subtotal resection was performed in 6 tumors (27.3%), including 3 neurofibromatosis associated with brachial plexus neurofibromas, 1 MPNST and 2 granular cell tumor in one patient. Conclusion : Resection of tumor is the choice of tumor in the most of benign and malignant brachial plexus tumors. Postoperative outcomes are related to grade of resection at surgery and pathological features of tumor.

원발성 흉벽종양은 흉부의 연조직이나 뼈 또는 연골에서 다양하게 발생할 수 있는 종양으로서 전체 원발성 종양의 약 l∼2%를 차지한다. 수술적 절제술은 만성 궤양이나 심한 통증이 있는 환자에서 효과적인 치료법이며 조직학적 진단 및 수술방법에 따라서 장기생존이 가능할 수 있다. 대상 및 방법: 1976년 9월부터 2001년 3월까지 원발성 흉벽종양을 가진 125명(양성종양 86명, 악성종양 39명) 의 환자에서 수술적 절제술을 시행하여 수술결과와 예후에 영향을 미치는 요소들을 해석하고자 하였다. 결과: 양성종양은 수술적 치료로 재발 없이 완전 치료가 되었으며 악성종양은 대부분 광범위 절제술을 시행하였으며 환자에 따라 수술 후 보조요법을 병행하였다. 양성종양 중 신경초종이 가장 많았으며 악성종양은 악성섬유성조직구종이 가장 많은 빈도를 보였다. 악성종양의 경우 3년 생존율이 76.0%, 10년 생존율이 60.5%이었다. 수술과 관련된 사망은 없었으며 외래 추적 중 사망한 환자의 원인은 원격 전이에 의한 장기부전 이었으며 11명에서 재발하였다. 안전거리 절제면을 4 cm 이상과 미만으로 구분하였을 때 두 군간의 생존율에 차이가 없었다. 결론: 양성종양의 경우 수술적 치료로 재발 없이 완치가 가능하였으며 악성종양도 비교적 좋은 장기생존율을 나타내었다. 안전거리 4 cm는 예후에 미치는 영향은 발견할 수 없었으나 재발 시에는 예후가 좋지 않았다.

A 59-year-old male patient had 5-month history of gait disturbance and memory impairment. His initial brain computed tomography scan showed $3.5{\times}2.8cm$ sized mass with high density in the pineal region. The tumor was hypointense on T2 weighted magnetic resonance images and hyperintense on T1 weighted magnetic resonance images with heterogenous enhancement of central portion. The tumor was totally removed via the occipital transtentorial approach. Black mass was observed in the operation field, and after surgery, histopathological examination confirmed the diagnosis of malignant melanoma. Whole spine magnetic resonance images and whole body 18-fluoro-deoxyglucose positron emission tomography could not demonstrate the primary site of this melanoma. Scrupulous physical examination of his skin and mucosa was done and dark pigmented lesion on his left leg was found, but additional studies including magnetic resonance images and skin biopsy showed negative finding. As a result, final diagnosis of primary pineal malignant melanoma was made. He underwent treatment with the whole brain radiotherapy and extended local boost irradiation without chemotherapy. His preoperative symptoms were disappeared, and no other specific neurological deficits were founded. His follow-up image studies showed no recurrence or distant metastasis until 26 weeks after surgery. Primary pineal malignant melanomas are extremely rare intracranial tumors, and only 17 cases have been reported since 1899. The most recent case report showed favorable outcome by subtotal tumor resection followed by whole brain and extended local irradiation without chemotherapy. Our case is another result to prove that total tumor resection with radiotherapy can be the current optimal treatment for primary malignant melanoma in the pineal region.

The malignant germ cell tumor found in the gonad can originate in the anterior mediastinum. Endodermal sinus tumor[Yolk sac tumor] is a kind of malignant germ cell tumor and is derived from extra-embryonic mesoderm. We experienced a case of primary mediastinal endodermal sinus tumor occurred in 22 year old male patient. His chief complaint was anterior chest pain for 2 days. The tumor located in the anterior mediastinum and invaded upper lobe of the deft lung and pericardium. A left upper lobe resection including phrenic nerve and pericardium was performed and the tumor in the anterior mediastinum was excised. The patient has been treated with combination chemotherapy[Cis-platinum, Vincristine, Actinomycin-D, & Cyclophosphamide} and followed up for 4 months with partial remission.

Ganglion cell tumors (GCT) are divided into two subtypes : gangliocytoma and ganglioglioma. Intramedullary gangliocytomas are extremely rare. A 20-year-old male patient with pain of neck, who also had a previously known neuroendocrine tumor of lung, was operated for mass found in the cervicomedullary junction with a presumptive diagnosis of metastases. Only partial resection could be performed. Pathological diagnosis had been reported as gangliocytoma. Only ten cases of intramedullary gangliocytoma have been reported in the literature. Although association with scoliosis and Von Recklinghausen;s disease were previously reported in the literature, no gangliocytoma case concomitant with endocrine tumor of lung have been published. Pathological study is the most important diagnostic method for gangliocytomas. Surgical excision is the primary treatment, but difficulty in total surgical tumor resection is the most important problem.

Primary adenoid cystic carcioma of trachea is rare, with an incidence of only 0.2 per 100,000 persons per year. When all series of the tracheal carcinomas are combined, adenoid cystic carcinoma is the second most common tumor only to squamous cell carcinoma in incidence. Most patients have wheezing or stridor, dyspnea, hemoptysis, and cough as symptoms. Treatment options include surgery alone, radiation therapy alone, or a combination of both. The recommended surgical option is primary tracheal resection and reconstruction. Recently, we experienced a case of adenoid cystic carcinoma in 45 year old female patient who was treated tracheal tumor resection and end-to-end anastomosis of the trachea, so we report this case with the literatures.

Giant cell tumors are primary bone tumors originating from non-osteoblastic connective tissue. The sites of involvement were commonly distal femur, proximal tibia, proximal humerus, distal radius and others (including os calcis, ilium and sacrum). Giant cell tumor located around knee joint has been difficult to treat because of local recurrence following curettage with or without bone graft. Although primary resections reduce recurrence of the lesion, the joint function will be markedly impaired. Marginal excision was very often complicated by a loss of joint integrity since all the giant cell tumors occupy juxtaarticular positions. Techniques involving physical adjuncts(high speed burr and electric cauterization) have been used in the hope of decreasing the rate of local recurrence and avoiding the morbidity of primary resection. A meticulous clinical, radiological and histological evaluation is needed to choose the correct treatment, keeping in mind the possibility of recurrence after each treatment modality.

The parathyroid carcinoma is a rare cause of primary hyperparathyroidism. There was approximately 170 reports in the would literature. and only two documented cases in Korean literature. It is still difficult to distinguish. histologically, benign from malignant parathyroid tumors. However, if diagnotic criteria are that strict, it can be suscessfully cured by initial operation. The initial operation should be an en bloc resection of the tumor, avoiding rupture of the tumor capsule and spillage of tumor cells. This report details the management of a 51 year old female with functioning parathyroid carcinoma who underwent an en bloc resection of the tumor at the time of initial operation.

Carotid body tumors are uncommon tumors of the head and neck Surgery is the primary treatment for the tumor. Large carotid body tumors frequently encircle the common, internal, and exernal carotid arteries, and extensive bleeding often complicates the resection, increasing the risk of carotid artery rupture and damange to major cranial nerves. Grafting should be used in high-risk patients. We have experienced a case of carotid body tumor which encircle the common, internal and external carotid arteries, treated with ligation of external carotid artery and grafting using Gortex between common carotid artery and internal carotid artery.
