This report is an analysis of 43 cases of primary mediastinal tumors and cysts which were treated in the Department of Thoracic and Cardiovascular Surgery, Tae Jeon Eul li General Hospital from January, 1986 to April, 1995. There were 19 males and 24 females, and their ages ranged from 4 years to 68 years, with mean age of 31.3 years. The most common symptoms were dyspnea 48.8%, chest disconyort 39.5%, cough )4.9%, and chest pain 23.3%, and the most frequently encountered location of tumor was anterior mediastinum followed by posterior, and middle mediastinum. From the pathologic viewpoint, teratoma was the most frequent type followed by neurogenic tumors, cysts, thymoma, and Iymphoma. The most useful diagnostic method was plain X-ray examination of the chest, and final diagnosis could usually be made only after an operation. All of benign tumors were completely removed and malignant tumors were treated with chemotherapy and radiotherapy after operation There were 7 (16.3 %) cases of postoperative complications, and there was no postoperative mortality.

Primary leiomyosarcoma of the mediastinum is an extremely rare tumor that develops either in the mesenchymal cells of the visceral mediastinum or in the smooth muscle of the great vessels. In the literature, the most significant factor for determining survival is the ability to completely resect the tumor. But there is 30~64% recurrence rate and there is also a lack of data for the role of adjuvant therapy after complete resection. We report here on a case of recurred leiomyosarcoma of the mediastinum that was surgically removed via left thoracotomy 2 years previously and this was misdiagmosed as benign disease.

Primary malignant fibrous histiocytoma of the lung is extremely rare, A 12-year-old child was admitted to the hospital due to an incidentally detected lung mass. A $2.5{\times}2.5 cm$ sized mass located in the right lower lobe was seen on the chest X-ray, the chest computed tomogram and the positron emission tomogram. We resected the mass through a right lateral thoracotomy and the mass was revealed to be a malignant spindle cell neoplasm on the frozen section diagnosis. So, we performed lobectomy of the right lower lobe with systemic dissection of the mediastinal lymph nodes; the final histopathological diagnosis of the mass was malignant fibrous histiocytoma. The patient was discharged on postoperative day 7 and adjuvant chemotherapy was not applied.

Glomus tumor is a distinctive type of perivascular tumor whose cell type is a modified smooth cell that closely resembles the glomus body, and this is where the tumor's name is derived. This kind of neoplasm is a benign and rather uncommon neoplasm that can be found in any part of the body, yet it is most commonly seen in the subungual area. Glomus tumor of the trachea is extremely rare. We present the clinicopathologic findings of a resected glomus tumor of the trachea along with a review of the related literature.

Malignant rhabdoid tumor is a highly aggressive tumor of children, that often arises in the kidney. Some rhabdoid tumors have been reported in various extra-renal location including the central nervous system, liver, skin, and soft tissues. In case of arising in soft tissues, it may be misdiagnosed as rhabdomyosarcoma. It is important to distinguish malignant rabdoid tumor from rhadomyosarcoma, because malignant rhabdoid tumor has more aggressive behavior and poorer survival rate. And this differential diagnosis can be performed by several immunohistochemistry. Here we report a case of malignant rhabdoid tumor that arose in lower abdominal wall with related articles.

Video-assisted thoracoscopic surgery has gained a broad acceptance for various thoracic lesions because it is the minimally invasive surgery with little tissue trauma, less pain, improved cosmetic results and short recovery time. However, there are some limitations for this method, such as restricted visual sensory information to a two-dimensional image and limited maneuverability of the tips of the instruments. To overcome these limitations, advanced technology has been introduced and the da $Vinci^{TM}$ Surgical System (Intuitive Surgical Inc, Mountain View, CA, USA) became available in 2001. In Korea, the da $Vinci^{TM}$ Surgical System was introduced in Severance hospital (Yonsei University College of Medicine) in May 2005, and approved by KFDA in July 2005. Herein, we report the first experience of robot-assisted thoracic surgery with the da $Vinci^{TM}$ Surgical System in extirpation of a large teratoma in anterior mediastinum.

Bronchogenic cysts are usually located in the pulmonary parenchyma or in the mediastinum. When bronchogenic cysts are located in the mediastinum, they are usually near the bronchus or esophagus, and rarely located in the retroperitoneal space. It is difficult to differentiate between bronchogenic cysts and benign cysts prior to surgert. We report here on a patient for who had a mass in the retroperitoneum, with the preoperative diagnosis being a benign neurogenic tumor. Via left open thoracotomy, pathologic reports revealed that the mass was a bronchogenic cyst. We report here on the case of a bronchogenic cyst that was located in the retroperitoneal space of the diaphragm.

Purpose: The purpose of the study was to evaluate the accuracy of two different fluid intake measurement methods (fluid only vs. all dietary intake) in measuring fluid balance compared to body weight change among patients with cancers. Methods: A total of 60 cancer patients in an urban cancer center in South Korea participated in the study. Adult patients who were over 18 years old; having 24-hour I&O order; and taking either normal regular diet or soft blend diet were included. Demographic information and disease related information were also gathered. The data were analyzed using SPSS 18.0 program. Results: Measuring 'fluid only' for oral intake was a more accurate measure than measuring 'all dietary intake' (p=.026 vs. p=.094). Both methods had positive correlations with the amount of weight change (r=.329, p=.010; r=.303, p=.019). Measuring body weight was a more accurate and efficient way of evaluating the fluid balance than 24 hour cumulative I&O. Conclusion: Developing clinical manual for selecting proper patients who needs fluid balance monitoring is imperative. Administering weight check and/or 24 hour cumulative I&O should be considered thoroughly based on solid nursing evidence in future.

Once it is diagnosed, immediate surgical extirpation is desirable for treating left ventricle myxoma that's accompanied with stenosis of the left ventricle outflow tract. This is because this condition may potentially induce fatal complications such as cerebral infarction or myocardial infarction that's triggered by myxoma embolus, or even sudden death due to coronary malperfusion. An 18-year-old male with the chief complaint of NYHA class II exertional dyspnea was found to have a $4{\times}3\;cm^2$ sized mass on transthoracic ultrasonography, which was shown to move down the left ventricle outflow tract on the systolic phase. The mass was immediately extirpated by incision of the left ventricle; the mass was finally diagnosed as a myxoma. The patient was discharged on at the 10th day postoperatively without any complications. On the 22-month follow-up observation made at the out-patient clinic after discharge, there have been no noticeable, significant changes seen on physical examination or the cardiac ultrasonography.

Most of the intraoral infections origin in odontogenic infection. Odontogenic infection spreads out along the least resistant path. In maxilla, the thickness between periapical area and cortical bone is narrower on the buccal side than the palatal side. So infection usually spreads out along the buccal side rather than the palatal side. The failure of root canal treatment more frequently occurs on the buccal root compared to the palatal root. So the palatal abscess is rarer than the buccal abscess. It is difficult to differential diagnosis palatal abscess from salivary gland tumors, benign neural tumors and cysts on the palate. Therefore, when the palatal swelling is observed in children, you need to prevent the systemic spread of infection by early diagnosis of the odontogenic palatal abscess. In these cases, the patient who complained of the pain in deciduous teeth and the palatal swelling was diagnosed with odontogenic palatal abscess. The patient was treated with extraction and antibiotic medication. The palatal abscess was resolved, and we report after treatments.
