A 31-year-old female was referred from other hospital due to migrating chest pain, mild cough, and blood-tinged sputum for three days before admission. Laboratory tests were unremarkable. Chest computed tomography revealed an elliptical necrotic mass at the left anterior mediastinum, measuring $7{\times}3{\times}4cm$. With the impression of mediastinal abscess or loculated empyema, thoracoscopic resection was performed. There was severe pleural adhesion around the mass. The mass could be resected by the wedge resection of the adhesed upper lobe tissue of left lung around the mass. Final pathologic diagnosis was ectopic pancreas.

Background and Objectives： Adenoid cystic carcinoma (ACC) is an aggressive, often indolent tumor, with a high incidence of distant metastasis (DM). Relatively little has been written about the factor that influence distant spread and subsequent survival because it is uncommon and has protracted clinical course. We attempted to reemphasize the biologic behavior of ACC by investigating the relationship between the clinical features and prognosis. Materials and Methods : We have retrospectively studied 24 determinate patiens who received definitive treatment in our hospital between 1984 and 1995 for ACC in all salivary sites. Inclusion criteria were no prior treatment elsewhere other than excisional biopsy and eligibility for follow-up of at least 5 years. Variables assessed for their impact on distant metastasis included age, gender, size, node status, stage, histologic pattern, locoregional treatment failure. Results : Treatment failure occurred in a total of 16 of 24 determinate Patients (64%), 12 of whom had DM (50%). This was usually associated with locoregional recurrence (8 patients), but DM was the only indication of failure in 4 whose primary tumor was controlled. Of the 12 patients with known DM, the lung was recored as the only involved site in 7 Patients, lung was involved in addition to other sites in 1, bone and liver metastasis occurred in 2 respectively. Disease-free intervals varied from 3 month to 14 years (median 3 years). The only significant factors influencing survival were the size of the primary tumor, locoregional recurrence. Conclusion : The high incidence of DM with locoregional failure confirms the importance of aggressive initial surgery. combined with irradiation, for high-stage tumors or involved surgical margins. Large tumor size and locoregional recurrence, rather than microscopic appearance, were predictive of DM.

Pulmonary lymphangioleiomyomatosis is a rare disease occurring almost exclusively in woman of reproductive age. It is characterized by rapid deterioration of respiratory functions and results in death within an average of 10 years. This disease is caused by a progressive proliferation of atypical smooth muscle in the pulmonary lymphatic vessels, blood vessels, and airways leading to the development of distal cystic changes which causes frequent recurrent pneumothoraces. We experienced a case of pulmonary lymphangioleiomyomatosis in a 30-year old woman who had a history of bilateral, recurrent pneumothoraces. The patient underwent lung biopsy through right thoracotomy which revealed the diagnosis of pulmonary lymphangioleiomyomatosis. We report a case with a review of the literature.

Lymphangioleiomyomatosis (LAM) is a rare disease that affects females of reproductive age. It is characterized by the abnormal proliferation of smooth muscle cells in the lung and along the axial lymphatics. We report a case of lymphangioleiomyomatosis presenting as a lung mass. The patient visited the emergency room because of dyspnea upon exertion. The chest X-ray showed a lung mass in the right lower lung field and a pneumothorax in the left lung. Chest computed tomography revealed a $5{\times}3cm$ sized mass in the right lower lobe and multiple thin-walled small cysts scattered in both lungs. Transbronchial biopsy of the lung mass was performed. The biopsy specimen showed atypical smooth muscle cell proliferation and cystic dilatation of the terminal bronchioles, which confirmed the diagnosis of lymphangioleiomyomatosis. To the best of our knowledge, this is the first case of lymphangioleiomyomatosis presenting as a lung mass.

Bilateral interstitial infiltration in chest radiography, which may be fine granular, reticular or of ground glass opacity, is the typical radiographic findings of Pneumocystis jiroveci pneumonia. Recently, atypical radiographic features, including cystic lung disease, spontaneous pneumothorax or nodular opacity, have been reported intermittently in patients with P. jiroveci pneumonia. We report the case of a 29-year-old woman with a transplanted kidney whose simple chest radiography and HRCT scan showed numerous miliary nodules in both lungs, mimicking miliary tuberculosis (TB). Under the presumptive diagnosis of miliary TB, empirical anti-TB medication was started. However, Grocott methenamine silver nitrate staining of a transbronchial lung biopsy tissue revealed P. jiroveci infection without evidence of TB. These findings suggest that even in TB-endemic area other etiology such as P. jiroveci as well as M. tuberculosis should be considered as an etiology of miliary lung nodules in mmunocompromised patients.

Lymphoid interstitial pneumonia (LIP) is a rare benign lymphoproliferative interstitial lung disease. LIP has been associated with autoimmune disorders, HIV, viral infections, and so on. Once underlying systemic diseases have been excluded, a diagnosis of idiopathic LIP can be made. Although 6 cases of pathologically confirmed LIP have occurred in Korea, thus far none has been associated with primary Sjogren's syndrome. A 44-year-old man was admitted to hospital due to a dry cough and dypsnea on exertion that had been ongoing for 2 months. A chest radiography showed multiple and variable-sized cystic lesions, on both lungs and both interstitial infiltration and consolidation in both lower lung fields. Tests for autoantibody showed positive results of anti-nuclear antibody and anti-Ro/La antibody. The patient underwent a video assisted thoracoscopic surgery biopsy and pathologically confirmed LIP. We report the first known case of LIP-associated with primary Sjogren's syndrome in Korea.

Objectives : Virus infection through the respiratory tract causes various inflammatory diseases such as pneumonia, cystic fibrosis, and obstructive pulmonary disease, causing enormous social damage. Therefore, it is very important to develop a treatment and prevention of infectious diseases. In this study, we investigated the effect of water extracts of Liriope muscari (WELM), known to improve lung function, on the inflammatory response of lung carcinoma cell line A549 cells induced by the viral double stranded RNA mimetic Polyinosinic:polycytidylic acid (Poly I:C). Methods : The cell viability by WELM treatment was analyzed using MTS assay in A549 cells. After inducing an inflammatory response to WELM-treated A549 cells with Poly I:C, the degree of apoptosis was confirmed through bright field microscopy. Interferon beta (IFN-β) mRNA expression level in A549 cells was analyzed by quantitative reverse transcription PCR (qRT-PCR). Results : WELM treatment has no significant effect on cell viability of A549 cells. We confirmed that pre-treatment of WELM effectively reduces the Poly I:C-induced apoptotic cell death in A549 cells. In addition, it was confirmed that the mRNA expression level of IFN-β, a pro-inflammatory cytokine increased by Poly I:C treatment, was significantly suppressed by WELM treatment in A549 cells. Conclusions : These results provide the evidence that WELM is effective at inhibiting inflammation on respiratory viral infections and suggest that Liriope muscari might be a valuable natural substance in the prevention and treatment of infectious diseases.

This is the result of the annual statistic analysis of thoracic and cardiovascular surgical cases in 1991, Korea. 14,715 cases of surgery[thoracic 8,995/cardiovascular 5,720] were done by 53 institutes replied. The order of frequency of cell type in primary lung cancer was squamous [62.3%] / adeno [23.9%] / small [6.4%] / adenosquamous [3.0%], and in mediastinal tumor, neurogenic[27.l%] / thymoma [27.1%] / teratoma[26.4%] / congenital cystic[12.0%]. Surgery for tuberculosis was decreased to 15.8% of overall infectious disease from the recent 6 year`s average 35.7%. In general thoracic surgery, the single most frequent operation was closed thoracostomy[4,047 cases] for pleural pathology. The ratio of congenital to acquired heart disease was 2:1, and acyanotic to cyanotic was 3:1. The order of frequency of congenital acyanotic heart disease was VSD [45.6%] / ASD [25.6%] / PDA [20.4%] / PS [2.9%], and that of cyanotic heart disease was TOF [42.6%] / PA [12.9%] / TGA [9.9%] / DORV [8.8%]. In 1,364 cases of valvular surgery, single mitral pathology was the most frequent candidate[729 cases, 53.4%]. In 243 cases of coronary surgery, bypassing graft materials were great saphenous vein[41.6%], internal mammary [39.5%], and artificial vessel[18.9%]. There were no specific differences in aortic surgery, assisted device implantation, and antiarrhythmic surgery as compared to previous study. This nation-wide inquiry will be continued and reported annually by KTCS Society.

Objective : Hydatid cyst disease is caused by the parasite Echinococcus granulosus. It is rarely seen in the vertebral system, occurring at a rate of 0.2-1%. The aim of this study is to present 12 spinal hydatid cyst cases, and propose a new type of drainage of the cyst. Methods : Twelve cases of spinal hydatid cysts, surgical operations, multiple operations, chronic recurrences, and spinal hydatic cyst excision methods are discussed in the context of the literature. Patients are operated between 2005 and 2016. All the patients are kept under routine follow up. Patient demographic data and clinicopathologic characteristics are examined. Results : Six male and six female patients with a median age of 38.6 at the time of surgery were included in the study. Spinal cyst hydatid infection sites were one odontoid, one cervical, five thoracic, two lumbar, and three sacral. In all cases, surgery was performed, with the aim of total excision of the cyst, decompression of the spinal cord, and if necessary, stabilization of the spinal column. Mean follow up was 61.3 months (10-156). All the patients were prescribed Albendazole. Three patients had secondary hydatid cyst infection (one lung and two hepatic). Conclusion : The two-way drainage catheter placed inside a cyst provides post-operative chlorhexidine washing inside the cavity. Although a spinal hydatid cyst is a benign pathology and seen rarely, it is extremely difficult to achieve a real cure for patients with this disease. Treatment modalities should be aggressive and include total excision of cyst without rupture, decompression of spinal cord, flushing of the area with scolicidal drugs, and ensuring spinal stabilization. After the operation the patients should be kept under routine follow up. Radiological and clinical examinations are useful in spotting a recurrence.

Bronchogenic cysts are anomalous cystic lesions of foregut and usually located in the lung or mediastinum. Generally intramuscular cysts of the esophagus are considered as enterogenous foregut malformations. We report a young adult with an intramural bronchogenic cyst causing dysphagia and heartburn. It was located in the muscular layer of the esophagus and was removed without any damage to the mucosa. Histopathologic findings revealed that it was a bronchogenic cyst.
