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.

The purpose of this study is to evaluate children who underwent hepatic resection for primary malignant hepatic tumor in the period from January 1994 to December 2001. A total of 8 patients, seven with hepatoblastoma (HB) and one with hepatocellular carcinoma (HCC), were studied. One HCC was resectable at the initial diagnosis, but five cases of unresectable HB received two cycles of transarterial chemoembolization (TACE) before operation. One patient with an unresectable HB with bone marrow metastasis was operated after one cycle of TACE and one cycle of systemic chemotherapy based on CCG-823F protocol. Another unresectable HB patient received systemic chemotherapy instead of TACE before operation. Postoperative chemotherapy was administered to all of the patients after complete surgical resection on CCG-823F protocol. All 6 patients who underwent TACE and neoadjuvant chemotherapy showed marked reduction in tumor volume and a clear outline of the lesion. Major complication was not noticed. Mean alpha-fetoprotein (${\alpha}$-FP) level at diagnosis, after neoadjuvant chemotherapy and after postoperative chemotherapy was 9,818 (42-35,350), 664, and 10.1 ng/mL, respectively. Half life of the ${\alpha}$-FP after complete resection was 5.1 days (3.0-8.7 days). Median follow up period was 57.1 months (10-97 months) and all the patients are alive with NED. In conclusion, preoperative chemotherapy, especially TACE, is effective, safe, and useful to treat initially unresectable hepatoblastoma, and serial level of the serum ${\alpha}$-FP is a useful tumor marker for diagnosis and monitoring therapeutic responses.

We report a rare case of primary intradural extramedullary myxopapillary ependymoma of the spinal cord. A 45-year-old woman was admitted to the author's institution with a history of progressive paraparesis[grade IV/IV] with back pain. Neurologic examination revealed decreased sensation below T12 sensory dermatome level. Magnetic resonance imaging[MRI] revealed an intermediate enhanced intradural extramedullary tumor extending from T12. Total resection of the tumor was achieved by T12 laminectomy. Intraoperatively, there was no finding of attachment to rootlet and dura. Histopathological examination identified the tumor as a myxopaillary ependymoma. To the best of my knowledge, this is the first reported case of primary intradural extramedullary ependymoma in Korea.

A 6-year-old spayed female French Bulldog presented with a left-sided chest wall tumor. Physical examination revealed that the tumor was firmly adhered to the chest wall. A preoperative punch biopsy of the tumor revealed a grade 2 soft tissue sarcoma (STS). On computed tomography, the tumor's dimensions were assessed as 6.5 × 5.7 × 3.5 cm, and it exhibited invasiveness near the tissue surrounding the ninth rib. The tumor size was large in comparison to the dog's chest wall area. Hence, if the traditional wide-margin resection surgery were to be performed, primary wound closure seemed impractical and could potentially result in respiratory function complications. Therefore, considering the extent of tumor invasion and grade, deep margins were established to include the removal of the eighth to tenth ribs, and a 1-cm lateral margin was designated to enable primary wound closure. To reconstruct the chest wall, polypropylene mesh was attached to the adjacent ribs and the remaining muscles were sutured and covered over the mesh. The dog exhibited a rapid recovery beginning the day after the operation. Postoperative biopsy confirmed that the tumor was a grade 2 STS, and the surgical margins were evaluated as incomplete. The owner chose to pursue follow-up observation instead of chemotherapy. In this study, the surgical approach was chosen based on the importance of functional recovery after surgery. Recent research indicates that the tumor grade is more critical for postoperative prognosis than the extent of surgical margins when removing an STS.

Sleeve resection is safe, effective, and appropriate treatment for a wide range of endo-bronchial lesions including neoplasms of low grade malignant potential and selected cases of bronchogenic carcinoma. Five cases of bronchoplastic procedures were performed for primary bronchogenic carcinoma patients at Department of Thoracic and Cardiovascular Surgery, Chonbuk National University Hospital from Aug. 1983 to Oct. 1987. Of the 5 patients, four were male and one patient was female and ages ranged from 51 years to 66 years old. Histopathologically, 4 cases were squamous cell carcinoma and one case small cell carcinoma. Operative procedures of the 5 patients were as follows: Right upper sleeve lobectomy, 1 case; Left upper sleeve lobectomy, 1 case; left lower sleeve lobectomy, 1 case; Left lower lobe and lingular segment sleeve resection, 2 cases. The early and late postoperative complications of the above operations were pneumonia, atelectasis, bronchopleural fistula, empyema, brain metastasis, and local recurrence of primary tumor.

Primary malignant fibrous histiocytoma (MFH) of the chest wall is extremely rare and is characterized by aggressive features, including a high incidence of local recurrence and distant metastasis. Surgical resection of the chest wall is the primary modality of management. However, surgical treatment is not generally recommended in patients with evidence of distant metastasis. Here, we present a case of chest wall MFH along with a schwannoma mimicking distant metastasis in the right upper arm. The patient was treated by radical en bloc resection and survived for more than 9 years without recurrence.

Primary cardiac fibroma of the left ventricular myocardium is a rare tumor of the heart which is usually located within the anterior wall and /or septum of the left ventricle and is the second most common cardiac tumor in infant and children. Although the tumor is benign histologically, it may cause severe cardiac dysfunction and sudden death. A 30-day-old neonate with a huge intramural fibroma involving the posterolateral wall of the left ventricle underwent it`s partial resection under extracorporeal circulation on April 1992.

Tracheal stenosis is being encountered more frequently as ventilatory support and cuffed tubes are increasingly used for treatment of respiratory failure. We experienced 13 cases of tracheal stenosis treated surgically at department of Thoracic and Cardiovascular Surgery, school of medicine, Kyung Hee university during the 4 years. The causes of tracheal stenosis were prolonged endotracheal intubation 5 cases, tracheostomy 3 cases, tracheal tumor 2 cases, thyroid tumor 1 case and congenital double aortic arch 1 case. The methods used to manage the tracheal stenosis were tracheal resection % end to end anastomosis 8 cases, 2 cases of subglottic stenosis were underwent primary laryngotracheal anastomosis, Lt. aortic arch division 1 case, and stent insertion 2 cases. In two cases, who had 6 cm in length of tracheal stenosis, we were underwent tracheal resection k end to end anastomosis with supralaryngeal release procedure. Postoperative courses were uneventful except one case with tracheal tumor.

Objective : The objective of this study was to evaluate the characteristics and surgical outcome of the conus medullaris tumors. Methods : We retrospectively reviewed 26 patients who underwent surgery for conus medullaris tumor from August 1986 to July 2007. We analyzed clinical manifestation, preoperative MRI findings, extent of surgical resection, histopathologic type, adjuvant therapy, and outcomes. Results : There were ependymoma (13), hemangioblastoma (3), lipoma (3), astrocytoma (3), primitive neuroectodermal tumor (PNET) (2), mature teratoma (1), and capillary hemangioma (1) on histopathologic type. Leg pain was the most common symptom and was seen in 80.8% of patients. Pain or sensory change in the saddle area was seen in 50% of patients and 2 patients had severe pain in the perineum and genitalia. Gross total or complete tumor resection was obtained in 80.8% of patients. On surgical outcome. modified JOA score worsened in 26.9% of patients, improved in 34.6%, and remained stable in 38.5%. The mean VAS score was improved from 5.4 to 1.8 among 21 patients who had lower back pain and leg pain. Conclusion : The surgical outcome of conus medullaris tumor mainly depends on preoperative neurological condition and pathological type. The surgical treatment of conus medullaris tumor needs understanding the anatomical and functional characteristics of conus meudllaris tumor for better outcome.

Primary tumors of the heart are extremely rare, and about 25 per cent of primary cardiac tumors are malignant. Recently, We experienced a case of primary cardiac liposarcoma occurred on the right ventricular outflow tract and extended into the main pulmonary artery. The patient was 57 year-old man and the chief complaints was severe exertional dyspnea. Emergency operation to relieve the right ventricular outflow tract obstruction was performed under cardiopulmonary bypass. The tumor was 5$\times$4$\times$3 cm in size and infiltrated into the right ventricle and ventricular septum. The tumor in the main pulmonary artery was removed without any difficulty but the on the right ventricular outflow tract was difficult to remove completely. The patient was recovered without any specific problems. After successful surgical resection and postoperative radiotherapy the patient discharged with good condition. Herein, the clinical characteristics of cardiac liposarcoma, the problems in differential diagnosis, the prognosis and current therapy are reviewed.
