Pneumatocele (PC) is a thin-walled cyst of the lung that can occur at all ages and with various etiologies. However, there is no fully accepted consensus for the management of PC in a neonatal intensive care unit. Although the management of PC is generally expectant, it is difficult to decide how long conservative management should be maintained, especially under Korea's medical care environment and the parents' worry and anxiety. We report a male neonate, born at $27^{+5}weeks$ gestation, weighing 1,000 g, who had a post infectious PC caused by methicillin-resistant Staphylococcus aureus sepsis. We treated conservatively for about 100 days (roughly 14 weeks), but unfortunately after a few days of chest retraction, acute exacerbation occurred, video assisted thoracoscopic surgery (VATS) was deemed necessary and performed. The purpose of this publication is to describe the clinical course, aggravation and relief after VATS management with a review of the literature.

기관지기원 물혹은 드물게 발생하는 선천성 질환으로 주로 종격동에 분포하며 기관지와의 소통이 발생하는 경우, 악성으로 전환된 경우를 제외하고는 크기가 갑자기 커지는 경우는 드문 일이다. 1년 전 검진에서 시행한 단순 흉부 촬영에서 이상이 없었던 젊은 남자가 흉부검진에서 종격동 덩어리가 발견되어 급격한 크기의 증가가 확인되었던 증례를 경험하였기에 문헌고찰과 함께 보고하는 바이다.

Wistar 계통 휜쥐를 면역억제하여 주폐포자충을 발현시킨 후, 기간 별로 폐단면 도말검사 표본에서 포낭의 수를 세고 폐 전체를 균질액으로 만들어 주폐포자충의 핵을 세었다. 또한 폐의 7개 부위에 따라서 포낭의 수를 비교하였다 포낭은 실험 3주가 되어서야 도말표본에서 20개의 1000배 확대 시야에서 평균 1개 이상이 검출될 정도로 나타났으나 폐 균질액에서 주폐포자충의 영양형은 실험 1주 후부터 $10^6$ 정도의 수가 계산되었다. 각 개체 별로 비교한 결과 도말검사에서 포낭형을 검출하려면 폐 전체에 적어도 $10^7$ 정도의 병원체가 있어야 된다는 사실을 확인하였다. 또한 20 개 시야에서 50 개 이상의 포낭을 관찰하는 경우에는 $10^9$ 이상의 병원체가 있다고 평가할 수 있었다. 좌우엽의 상, 중, 하 세 부분과 소엽(accessorylobe)의 부위에 따른 포낭의 수에서 어떠한 의미있는 경향을 인정할 수 없었다. 이 실험 자료를 통하여 폐 단면 도말표본에서 포낭의 수를 세는 것을 전체 병원체의 수를 파악하는 방법으로 사용할 수 있다고 판단하였다. 또한 주폐포자충은 감염 초기에 영양형으로 시작하여 일정수가 되어야 포낭형이 출현하는 것으로 추측하였다.

Congenital cystic adenomatoid malformation (CCAM) is an uncommon, nonhereditary anomaly caused by arrest of lung. Patients with CCAM may present with respiratory distress as newborns, or may remain asymptomatic until later in life. CCAM type I is rarely found in association with bronchial atresia (BA) in adults; we present such a case. Case: A 54-year-old female presented with chronic cough and blood-tinged sputum. Physical examination and laboratory tests were unremarkable. Chest radiographs and a CT scan of the chest showed multiple large air-filled cysts consistent with a CCAM in the right lower lobe, and an oval-shaped opacity in the distal right middle lobal bronchus. Based on the radiologic findings, right middle lobectomy and a medial basal segmentectomy of the right lower lobe were performed via a thoracotomy. These lesions were consistent with Stocker's Type I CCAM and BA in the different lobes.

Primary renal tumors are uncommon in dogs with prevalence rate of approximately 1%. Renal carcinoma originating from epithelium of proximal convoluted tubules are more likely to be affected to Middle-aged dogs (average age, 8y), males about twice as often as bitches. A 10-year-old, female, German Shepherd dog with history of anorexia, vomitting and hematuria was referred to the Animal Disease Diagnostic Division in Animal and Plant Quarantine Agency. The dog was necropsied and several organs were collected, fixed in 10% phosphate-buffered formalin, embedded in paraffin wax and sectioned for histopathology. Grossly, the kidneys were bilaterally enlarged ($18{\times}12{\times}8cm$; left, $18{\times}10{\times}8cm$; right). The numerous cysts varying sizes from 3 to 6 cm in diameter were protruding from the surface of both kidney. A large nodule ($10{\times}6{\times}6cm$) was discovered between cardiac and diaphragmatic lobe in the right lung. Immunohistochemical examination revealed strong positive reaction to cytokeratin and ki-67 in the nuclei of the epithelial tumor cells. But showed negative reactions to vimentin and CD10. Based on the pathological and immunohistochemical examination, we diagnosed as the bilateral renal cystadenocarcinoma in German shepherd dog.

기관지성 낭종은 보통 단순 흉부 사진상 폐실질이나 종격동 내에 얇고 때끄러운 벽을 가지며 경계가 뚜렷한 원형의 종괴 흑은 낭포로 발견되고 보통 Hounsfield Number 0-20의 음영을 가진다. 본 증례는 단순 흉부 방사선 소견 상 폐실질내 경계가 불분명한 종괴로 보이고 CT상 Hounsfield Number 26의 연조직 음영을 보여 폐암을 배제하기 위하여 수술까지 하였던 경우였기에 보고하는 바이다.

Lymphangioleiomyomatosis is a rare disease which afflicts young women of childbearing age. We experienced a 32-year-old female who was admitted because of worsening exertional dyspnea after hormonal therapy with Clomifen for five months and intermittent hemoptysis. Chest PA showed diffuse ground glass appearance with some reticular infiltrations. High resolution CT scan showed multiple small thin walled cysts distributed homogeneously throughout the entire lung. Pulmonary function test showed characteristic obstructive pattern despite the restrictive interstitial pattern of chest radiography. Thoracoscopic lung biopsy specimen showed abnormal proliferation of smooth muscle cells in the walls of lymphatic vessels, bronchioles, and pulmonary vessels typical of pulmonary lymphangioleiomyomatosis. Hormonal therapy with medroxyprogesterone was initiated.

This is to report a case of bronchgenic cyst. While most of the bronchogenic cysts reported in the literature so far were located either in the lung parechym or in the mediastinum near the tracheal bifurcation or main bronchi. the cyst presenting in this study was originated in the wall of the esophagus and was reported to be very rare. The cystic tumor was found accidentally by X-ray fluoroscopic examination of the esophagus and stomach in the patient with gastric hemorrhage. X-ray study revealed that the cystic tumor was oval in shape and located in the left posterolateral wall of the esophagus in the thoracic lower third. Two surgical operations, gastrectomy for gastric hemorrhage and the resection of the cystic tumor, were carried out separately. Gastrectomy including the removal of prepyloric ulcer by the Billroth II type procedure was performed in regular fashion, and the cystic tumor was resected radically without any injury of the mucous membrane of the esophagus. The cyst removed appeared to be filled with mucinous material, and histological examination identified the tumor as a bronchogenic cyst with ciliated epithelial internal lining. Postperative course of the patient was uneventful.

55세 여자환자가 좌측 목과 어깨 통증을 주소로 내원하였다. 흉부 전산화 단층촬영상에서 전종격동 종양이 발견되었으며, 폐 혹은 흉강 내에 다른 병변은 보이지 않았다. 감염성 심막 낭종 의심하에 흉강경을 이용하여 종괴 적출술을 시행하였다. 환자는 술 후 2일째에 좌측 횡격막 마비를 제외하고는 특별한 문제 없이 퇴원하였다. 수술 후 병리 소견에서 폐흡충증로 진단 후 프라지퀀탈(praziquantel)을 투여하였고, 이후 특별한 문제 없이 외래 경과관찰 중이다.
