Hemangiopericytoma is a rare vascular tumor derived from the pericyte and usually occures in the lower extremities and the retroperitoneum. Complete excision is treatment of choice. Regular follow up is strongly recommended due to its potential malignancy which is recurrence and metastasis. We experienced surgical excision of metastatic pulmonary hemangiopericytoma from retroperitoneal hemangiopericytoma completely excised 10 years ago.

We experienced one case of endobronchial hamartoma on left lower lobar bronchus in sixty year old male patient. Less than 1 % of lung tumors are benign, and the prevalence of endobronchial hamartoma is reported to be from 3 % to 40 %. The mean age was 52.9 years, and equal gender prevalence.Symptoms were related to intraluminal growth, including fever, chill, productive cough, hemoptysis, exertional dyspnea, recurrent pneumonia and so on. Bronchoscopic finding was tumor present as polypoid mass in the lumen of a left main stem bronchus,distal to 3 cm from carina. Biopsy was done. The histopathologic pattern showed several nodules of loose myxoid tissue and islands of cartilage. We performed partial resection of the affected bronchus,1cm anterior to the superior segmental bronchial opening to just distal from superior segmental orifice. Including superior segmentectomy, partial resection of the left lower lobar bronchial resection and end-to-end anastomosis with 4-0 Poly dioxanone sutere materials interruptedly. We report this case with the brief review of literatures.

Desmoid tumors are benign neoplasms with high rates of recurrence. A case of huge desmoid tumor of the intrathoracic and intraabdominal space is presented. The patient was treated with resection, which involved hepatic left lobectomy and diaphragmatic resection and partial pericardiectorny and wedge resection of left lower lobe of lung. The resulting defect over the pericarium and diaphragm was reconstructed by bovine pericardium and Marlex mesh. Prevention of presumed local recurrence of desmoid tumors requires wide excision margin.

Primary pulmonary liposarcoma is extremely rare disease. It has poor prognosis with early multiple metastases and frequent local recurrences. Surgery is the choice of treatment for liposarcoma. Incomplete resection would result in rapid and aggressive growing of the tumor. We report a case of primary pulmonary liposarcoma which was successfully treated with complete resection without local recurrence and distant metastasis for 10 months.

이 논문에서는 우리나라 사망원인의 1위인 악성신생물 중에서 2000년부터 가장 빈도가 높은 폐암에 대하여 우리나라와 OECD 국가들 간에 사망률과 잠재수명손실연수(PYLL)에 통계학적으로 차이기 있는가를 살펴보아서 폐암에 대한 국가 간 비교와 폐암 사망구조의 문제점을 파악하여 보건정책, 보건교육, 보건자원배분 등에 자료를 제공코자 한다.

We describe the case of a 58-year-old woman who has coexisting intrapulmonary and mediastinal leiomyomas. Initially, she was seen with a single mass in the right lower hilar area in a simple chest roentgenogram. But computed tomography demonstrated another mass in the right posterior mediastinum. Microscopic examination and immunohistochemical staining of the resected specimens showed the characteristics of the leiomyoma.

Endodermal sinus tumor[EST] of the mediastinum is a rare germ cell neoplasm. It usually arises from the ovaries and testes but also arises from multiple extragonadal site including the mediastinum. Characteristically, alpha feto protein level is high and used for monitoring the clinical course. EST of the mediastinum is poor prognosis because of its direct invasion. The patient was 18 month old female with chief complaints of cough and fever. In the chest X-ray and CT, large encapsulated, 7x6cm sized, mass of anterior med-iastinum was found, and we could excise it completely because it was well encapsulated and not invaded but only adhered to aortic arch, pericardium and left upper lung. And confirmed it as EST by histopathology. Pre-operative alpha feto protein[AFP] level as 41,748ng/ml and decreased to 2, 663ng /ml at 14th postoperative day, 644ng /ml at 31th postoperative day. From 17th post-operative day, chemotherapy was started and keep going now.

Metastases to the liver can be found in various malignancies, most commonly originating from the colon, rectum, pancreas, stomach, esophagus, breast, lung, and melanoma. Surgical resection of liver metastasis is generally considered to be the definitive therapy fore cure. However, many patients are unable to undergo surgical resection due to medical comorbidities or multifocal extent of malignant disease affecting the liver. Among patients not eligible for surgery, other therapies exist for treatment in order to down stage the disease for surgical resection or for palliation. Radioembolization of hepatic metastases has shown to improve outcomes among patients with variety of malignancies including more common malignancies such as colorectal cancer. Yttrium-90 (Y-90) radioembolization has been successfully used in the management of hepatic metastases. A small series of metastatic sarcoma to the liver treated with radioembolization showed a promising response. We report a case of metastatic gastric leiomyosarcoma to the liver treated with Y-90 glass microspheres therapy using the radiation segmentectomy approach, previously described for hepatocellular carcinoma.

Mucinous adenocarcinoma (MAC) is a rare malignant neoplasm that occasionally occurs in the large intestine (colon), followed by the pancreas, ovary, lung, prostate, and breast. It is characterized by large amounts of extracellular epithelial mucin that contains tumor cell nests. We herein present a unique case of MAC originating from minor salivary gland, the second to be reported in literature in South Korea. We report a case of MAC in the tongue considered to be developed from minor salivary gland with a review of literature.

Mediastinal paragangliomas are rare tumors that have only been reported in individual cases or limited case series. Surgical resection of these tumors can be challenging, as they are highly vascular and intimately related to the great vessels. Surgery is usually performed via median sternotomy with or without cardiopulmonary bypass. We present the case of a mediastinal paraganglioma that was resected via a left-sided posterolateral thoracotomy. Histopathology revealed a completely resected 38-mm paraganglioma with a positive station 5 lymph node, indicative of locally aggressive disease. Hereditary paragangliomas are associated with malignant transformation; therefore, genetic testing is important. These tumors do not respond well to chemoradiotherapy, and consequently lifelong surveillance for early detection of recurrence is recommended.
