A solitary fibrous tumor (SFT) is a mesenchymal fibroblastic tumor inside the pleura, for which complete surgical resection is the standard treatment. For large SFTs, preoperative identification of tumor-feeding vessels using angiography is important for achieving complete resection without unexpected operative bleeding. Extensive adhesions can make resection difficult in a limited operative window, and pulmonary resection may be required to achieve complete SFT resection. Herein, we report successful resection of a large pleural SFT in a 39-year-old man without any complications using a 2-stage approach, in which ligation of the feeding vessels through small another operative window was the first step.

Objectives : Meningeal hemangiopericytoma is a rare tumor. Clinical and radiological features are similar to those of an ordinary meningioma. But its biological behavior is quite different from those of a meningioma as it brings profuse bleeding in the operation field, frequent recurrence and metastasis to other systemic organs even in the case of gross total resection. In order to find out the prognostic factors and to compare longterm outcome after various treatment modalities, the authors reviewed consecutive 20 operated cases of meningeal hemangiopericytoma to characterize their clinical features, surgical outcomes and effectiveness of the radiation therapy. Methods : Twenty patients with a hemangiopericytoma were treated between 1982 and 1999 in our department. They are composed of 13 patients of hemangiopericytoma and 7 patients who were initially diagnosed as angioblastic type meningioma and then confirmed as a hemangiopericytoma after review of their previous histopathology slides. The mean follow-up period was 99 months(1-256 months). The long-term outcomes after various treatment modalities were evaluated according to recurrence-free survival and image follow-up. Recurrence-free survival curves are compared between the patient groups according to the extent of removal and radiation therapy. Results : There were 10 cases of recurrence and 4 cases of distant metastases ; lung, liver and femur(2 cases) respectively. The 5-year recurrence rate was 37%, while the 10-year recurrence rose to 77%. There was also statistically significant difference of median recurrence-free survival between the completely-resected group(Simpson grade 1 or 2) and partially-resected group(Simpson grade 3 or 4 or 5) ; 137 months compared to 47 months, respectively(p=0.009). The median recurrence-free period after subtotal resection of tumor and postoperative radiotherapy was 47 months compared to 117 months of the patients who underwent gross total resection of tumor and did not receive radiotherapy. But radiation therapy alone did not show significant difference in recurrence-free survival. Marked tumor volume reduction and easy removal of tumors without bleeding were found in 2 recurred cases. Conclusion : The extent of tumor resection and presence of metastasis are the most important factors related to long-term outcome of the patients with hemangiopericytoma. Radiation therapy after the first operation did not have a role in extending the recurrence-free survival, but it affected favorably to decrease the size of residual mass and intraoperative bleeding during the second operation.

Objectives: A 74-year-old male patient with unresectable advanced gastric cancer (clinical initial stage T3N+, Borrmann type III) admitted due to gastric bleeding at tumor site. On first admission day, hemoglobin level was 5.7g/dl and performance status was grade 3 according to Eastern Cooperative Oncology Group Performance Status(ECOG-PS). After performing red blood cell transfusion as an emergency treatment, hemoglobin level was increased up to 9.5g/dl. However, bleeding of oozing site was continued. For hemostasis, decoction of notoginseng radix (30g/day) was administered since day 7 after admission. The dose was elevated to 40g/day after hemoglobin level was decreased to 6.5g/dl on day 11. Since then, melena was stopped and hemoglobin level was maintained over 9.1g/dl. This case shows the hemostasis effect of decoction of notoginseng radix on gastric bleeding in unresectable advanced gastric cancer.

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.

목적: 위 점막하 종양(gastric submucosal tumor, gastric SMT)은 최근 건강검진의 보편화로 증가하는 추세에 있다. 이에 반해 악성도에 따라 예후가 달라지고, 방사선 검사나 내시경 조직검사로 다른 종양과의 감별이 어려워 아직도 치료 방침을 결정하는데 어려움이 있다. 이에 저자들은 위 점막하 종양 환자에서 임상병리학적 특성을 분석하고, 이에 따른 복강경 수술과 개복술의 결과를 각각 비교 분석하였다. 위 점막하종양의 복강경 절제술의 학습곡선 의미를 도출하여, 위 점막하종양의 적절한 치료방법을 제시하고자 한다. 대상 및 방법: 2003년 4월부터 2008년 8월까지 본원에서 위점막하종양으로 개복 위절제술을 받은 25명과 복강경 위절제술을 시행 받은 78명의 환자들을 대상으로 하였으며, 수술 후 임상경과 및 병리학적 특징에 대하여 전향적인 자료 수집 후 후향적으로 결과를 비교 분석하였다. 결과: 환자의 평균 연령은 53.7세(22~80세)였으며 남녀비는 각각 44명, 59명으로 1 : 1.34였다. 대부분 무증상으로 내원하였으며, 주로 쐐기형 위절제술을 시행 받았다. 종양의 평균 장경은 4.33 cm (1.2~17.0 cm)였고, 주로 위상부에 위치하였으며, 평균 수술 시간은 117.3분(35~255분)이었다. 평균 출혈량은 113.9 ml (0~1,000 ml), 평균 수술 후 재원기간은 8.0일(1~69일)이었다. 술 전 내시경적 절제술이 실패하여 수술이 의뢰된 환자가 5명 있었다. 수술 후 합병증은 13명(12.6%)에서 발생하였고, 수술과 관련된 사망은 없었다. 위 점막하종양의 대부분은 간질유래성증양으로 58명(56.3%)이며, 이중 현재까지 크기가 5 cm 이상이고 복강경 위절제술을 시행한 2명이 재발되었다. 복강경 수술 군과 개복 수술 군에 따라 수술 시간 및 출혈량, 합병증에는 차이가 없었지만, 두 군 간에 환자의 증상(P<0.001), 종양의 크기 (P<0.001), 수술방법 중 쐐기형 절제술 시행(P=0.037), 술 후 연식섭취 시간(P<0.001), 술 후 퇴원 일(P=0.002)에는 차이가 있었다. 위 점막하종양의 복강경 위절제술은 26예 이상의 수술 경험이 필요하고, 이러한 학습 곡선을 극복함으로써 수술 시간, 출혈량을 줄일 수 있다. 결론: 5 cm 미만의 위 점막하종양에서는 복강경적 치료방법이 개복술보다 안전하고, 효과적인 치료방법으로 생각되며, 다양한 형태의 위 점막하종양을 복강경적 절제술로 시행 할 경우에는 학습 곡선을 먼저 극복하기 위해 노력하는 것이 권장된다.

Gastric glomus tumor is a rare mesenchymal tumor that originates from modified smooth muscle cells of the glomus body. Glomus tumors are commonly observed in peripheral soft tissue, such as dennis or subungal region, but rarely in the gastrointestinal tract. A 39-year-old woman was admitted due to epigastric soreness. Upper gastrointestinal endoscopy revealed a subepithelial mass measuring 3.5 cm with central ulceration at the lesser curvature-posterior wall of the antrum. Characteristically, contrast enhanced abdominal computed tomography scan demonstrated high enhancement of the submucosal mass up to the same level of the abdominal aorta in the arterial phase; this enhancement persisted to delayed phase. Due to the risk of bleeding and malignancy, wedge resection of the submucosal tumor was performed. Histologic findings were compatible with a glomus tumor.

We report a supratentorial primitive neuroectodermal tumor (sPNET) in 17-year-old primipara in the second trimester her pregnancy. Magnetic resonance imaging revealed a left frontoparietal mass with solid and cystic component. Gross-total resection was achieved via a left frontoparietal craniotomy. It was decided to suspend the radiotherapy and chemotherapy until the 30 weeks of gestation. But, a sudden uncal herniation was developed due to the reccurrence of the tumor and bleeding into the tumor at the 25 weeks of gestation and the patient died after urgent decompressive surgery. sPNETs is an extremely rare brain tumor in pregnancy and only two cases were reported in the literature to date. There is no universally agreed treatment protocol for sPNETs during pregnancy and a multidisciplinary approach is required in treatment. In the present study, the clinical, histopathological features and therapeutical difficulties of sPNETs diagnosed during pregnancy was discussed with the literature review.

Undifferentiated sarcomas are rarely identified in the intracranial region. A 23-year-old man was admitted with a chief complaint of headache. Initial magnetic resonance images showed signs of low-grade glioma in the frontal lobe. Stereotactic biopsy was performed, and a diagnosis of diffuse astrocytoma was confirmed. Three months later, the patient presented with a high-grade tumor as seen on imaging studies. He underwent total resection of the tumor and histopathological tests identified an undifferentiated sarcoma. The patient died eight months later due to massive tumor bleeding. To the best of our knowledge, this is the first report of undifferentiated sarcoma arising from low-grade glioma without any chemotherapy or radiotherapy.

The authors present a case of 68-year-old woman who underwent resection of a metastatic adenocarcinoma in the left parietooccipital area. The intraoperative course was uneventful; however, after closure of the scalp incision, increased bleeding from the suture line was noted. A computerized tomography scan that was performed immediately after operation revealed acute epidural hemorrhage with mass effect under the bone flap. The patient developed disseminated intravascular coagulation and immediate re-exploration was performed. This patient was successfully treated owing to early recognition of the condition and immediate treatment with transfusion. Neurosurgeons should be alert that hypercoagulabe state is common in cancer patients and consumptive coagulopathy can occur after resection of metastatic brain tumor.
