Among varieties of the mediastinal tumors, benign developmental cysts [Entergenous cysts] occur about 10% of them. From the primitive foregut, tracheobronchial tree and esophagus develop at 3 weeks of its embryonal age, and bronchogenic cyst arises from accessory or supernumerary lung bud. Usually it remains isolated with surrounding structures, and causes no specific symptoms. But few cases of bronchogenic cysts have fistulous communication with esophagus causing compressive symptoms. We report a case of unusual complicated case of bronchogenic cyst with review of literatures.

Echinococcal or hydatid cyst is one of the most important zoonoses and commonly seen throughout the world, especially sheep and cattle raising areas, but rare in Korea. The causative organism, Echinococcus granulosus, is a small tapeworm and dogs are the usual source of infestation. Lung is the second most common focus for this disease, after liver. Recently, with increasing numbers of Koreans visiting to those endemic countries especially Middle East, the reports of hydatidosis are increasing. Authors experienced two cases of pulmonary hydatid cyst in the 31 year old male and 44 year old male who had a history of spending 2 * 3 years in Middle East. we found them in incidental routine chest X-ray.

Hydatid disease is a parasitic infection that is caused by the larval stage of Echinococcus granulosus. This disease is distributed worldwide, but it is rare in Korea. A 34-year old foreign male worker from Mongolia presented with cough and chest discomfort. Computed tomography of. the chest showed a cystic mass in the upper lobe of the right lung. The cyst was surgically resected, and the pathological study confirmed a hydatid cyst. The patient was given albendazole postoperatively to prevent a relapse. We report here on a surgical case of pulmonary hydatid disease along with a review of the literature.

A 16-year-old female Bengal tiger (Panthera tigris tigris) infected with Paragonimus kellicotti was described. Noticeable clinical symptom was not observed before death. At autopsy, numerous cysts were found on the pleural surface of the lung. The cysts were spherical, approximately 1.0 cm in diameter, bulge the pleura, and dark red-brown in color. Such cysts were also found in the deeper lung parenchyma, and usually contained adult flukes in pairs. Histopathologically, the cyst was lined with stratified squamous epithelium which arose from metaplasia of bronchial epithelium. Partial hyperplasia and necrotic foci accompanied with inflammatory cells were often observed in the squamous epithelium. The outer part of the cyst was consisted of fibrous connective tissue in which leukocytes were infiltrated. Catarrhal pneumonia was manifested in the adjacent lung tissues.

Bronchogenic cysts are uncommon congenital lesions which are derived from primitive foregut. Most of the bronchogenic cysts may occur at the tracheal bifurcation, both main bronchi, the lung parenchyme and the mediastinum. We experienced a case of bronchogenic cyst with a esophageal stalk. The diagnosis was made by simple chest x-ray and confirmed by bronchoscopy and chest CT. On the chest CT findings, 6.8X4.8 cm-sized oval shaped mass was located on the right posteroinferior side of the carina, elevating the right main bronchus and the thin wall of the mass was enhanced with contrast materials. On the operative findings, the esophagus and the cyst were connected with a stalk and the cyst was filled with mucinous materials. And on the histological findings, the mass was lined with pseudostratified ciliated columnar epithelium. Thus we report this case of bronchogenic cyst with review of literatures.

Intrathoracic cyst was considered rare entity but one of the important diseases in the field of thoracic surgery. Authors had experienced 17 cases of intrathoracic cysts that were treated in the department of thoracic and cardiovascular surgery of Pusan NationalUniversity Hospital for 10years from January, 1983. to December,1992. The summary is as follows: Their age distribution was from 2 years and 9 months to 59 years of age, mean age 27.2 years. There were 8 males and 9 females. The type of intrathoracic cyst was 10 cases of Bronchogenic cyst, 2 cases of Pericardial cyst and 4 cases of Non specific cyst. The anatomical locations of intrathoracic cysts were 6 cases of anterior mediastinum, 2 cases of middle mediastinum, 3 cases of posterior mediastinum and 6 cases of lung parenchyme. The most common symptom was coughing and followed by general weakness, fatigue, chest pain & discomfort and hemoptysis and 6 patients were asyptomatic. The successful complete removal was done at all cases.Postoperative complications were developed in 5 patients but there was no case of hospital mortality.

The bronchogenic cysts result from an abnormal budding or branching of the tracheo-bronchial tree from the primitive foregut. Bronchogenic cysts may be pulmonary or mediastinal. The most common location for a mediastinal bronchogenic cyst is in relation to the carina. They are usually solitary. They usually are thin walled and contain fluid that is most often clear. The cyst is lined by ciliated columnar epithelium. The bronchogenic cyst i~ usually asymptomatic. They can cause pressure symptoms. When they become infected, symptoms do occur. We report 3 cases of bronchogenic cysts experienced at the Department of Thoracic and Cardiovascular Surgery, Kyungpook National University Hospital. Case I, a man of 20 year-old, had a cyst at the site between aortic arch and left pulmonary artery. He complained cough and dyspnea. The cyst wasn`t communicated with tracheobronchial tree. Case II was 55-year-old male who had had hemoptysis. A huge cyst was located within the lower lobe of left lung and removed by pulmonary lobectomy. There were not any symptoms in Case III that was 6-year old girl. That cyst was located just next to the right main bronchus.

Sclerosing hemangioma is a rare, benign neoplasm of the lung, usually presented as a solitary pulmonary nodule in an otherwise asymptomatic middle-aged woman. Cytologically it shows papillary, sheet, and cyst-like arrangements representing three main histologic patterns of papillary, solid, and angiomatous ones, respectively. Herein, we report the fine needle aspiration cytology of 5 cases of sclerosing hemangioma of the lung. The most characteristic finding is cyst-like spaces Intimately related to the papillary or solid cell nests. The tumor cells are relatively monotonous round to oval, small to medium in size. They have small amount of eosinophilic cytoplasm. The nuclei are uniform, round and have small but conspicuous nucleoli. The tumor cells in one of the presenting cases are large with abundant cytoplasm and show moderate nuclear pleomorphism. The nuclear chromatin, however, is fine and even without exception, even in the case showing nuclear pleomorphism. Major differential diagnoses based on the cytologic findings are well-differentiated papillary adenocarcinoma, bronchioloalveolar carcinoma, and carcinoid tumor.

A lung cyst is an air-filled lucent structure surrounded by a thin wall. The presence of multiple intrapulmonary cysts is defined as cystic lung disease. Although cystic lung disease is rare, incidental detection has increased significantly in recent years by screening using computed tomography. There are many conditions that can mimic lung cysts and cause cystic lung disease. Clinical, radiographic, and histologic findings are all necessary for a proper diagnosis, and multidisciplinary approaches are frequently required. The aim of this report is to review the causes and characteristics of cystic lung disease to better understand and improve treatment.

The congenital cystic adenomatoid malformation of the lung is a rare disease, and is one of the most common congenital lung diseases which require prompt surgical intervention. The prognosis depends on its tissue type, prompt diagnosis and surgical intervention. The lesion consists of enlarged, variable sized multiple cyst with overgrowth of terminal bronchioles, like hamartoma. This disease can be associated with other vascular anomalies or other congenital defect especially in type II lesion We recently experienced one case of congenital cystic adenomatoid malformation The patient was 2 months old infant who showed respiratory distress without associated anomaly. After right upper lobe lobectomy, the patient was recovered uneventfully.
