Background : A pulmonary tuberculoma is one of the most common causes of a solitary pulmonary lesion. Treating a tuberculoma is still controversial and there are few reports on antituberculosis chemotherapy. In this study, the clinical findings and changes in the size of tuberculomas on a radiograph after completing antituberculosis chemotherapy was investigated. Methods : The medical records, an chest radiographs of 18 pulmonary tuberculoma patients who were admitted to the Gachon medical school, Ghil medical center between April 1998 and August 2001, were reviewed. The symptomatic changes were recorded and the size of the tuberculomas following treatment were compared. To compare the size, the long distance of each tuberculoma on the chest radiographs were measured and the additional radiological findings of calcification, satellite nodules and cavities were investigated. Results : Fifteen patients were men and 3 were women. The median age was 46 (24-74). Among these 18 patients, 14 patients had clinical symptoms. The other 4 patients were diagnosed incidentally as during a routine chest radiograph. The mean size of the tuberculomas on the initial plain chest film was $4.3{\pm}2.3cm$(range : 1.7-10 cm) and after 6 months treatment, it had decreased to $1.68{\pm}2.00cm$(range : 1.5-6.5 cm) (P<0.05). At least 6 months of antituberculosis chemotherapy resulted in the findings of a tuberculoma with a disappearance in 9, a decreased size in 4, and no change in 5 on the chest radiograph. Calcifications were found in 3 patients on the initial chest film and the chest CT and all calcified tuberculomas had disappeared after treatment. Conclusion : Although a pulmonary tuberculoma can remain as an inactive lesion for a long time, if it is confirmed by pathological or bacteriological methods, antituberculosis chemotherapy will be beneficial despite the presence of calcification.

Swyer-James syndrome is a rare disease with patients presenting with unilateral hyperlucent lungs and hypoperfusion due to hypoplasia of the pulmonary artery and bronchiolitis obliterans. A unilateral hyperlucent lung generally develops after a lower respiratory tract infection during early childhood. In extremely rare cases, an association of bronchogenic carcinoma with Swyer-James syndrome has been reported. We report a case of bronchogenic squamous cell carcinoma associated with Swyer-James syndrome that performed right upper lobectomy and lymph node dissection with a relevant literature review.

폐모균증은 드물지만 치명적인 기회감염성 진균증으로 혈액종양, 신부전, 또는 당뇨와 같이 면역기능이 저하된 환자에서 주로 발생한다. 환자는 3년전부터 당뇨병 및 갑상선기능 항진증을 앓아온 32세 남자로 1개월간의 기침, 발열 및 좌측 흉통을 주소로 내원하였다. 기관지 내시경하 경기관지 폐생검상 폐모균증 진단되어 좌폐하엽절제술을 시행하였다. 술후 21일째 흉부방사선 사진 소견상 다수의 국소적인 흉막삼출로 흉강경을 이용한 배약술을 시행하였다. 환자는 술후합병증이 없이 흉강경배액술후 23일째 퇴원하였다. 기왕의 문헌보고에 의하면, 한쪽폐에 국한된 모균증을 가진 수술가능한 환자에서는 조기에 과감한 수술적 처치가 생존율을 높이는 것으로 제안하고 있다.

Capillary hemangioma is the most common vascular tumor in childhood; however, its occurrence in the bronchus is extremely rare. We recently performed a sleeve resection of the left main bronchus on a four-month-old infant with a severe emphysema caused by bronchial capillary hemangioma.

53세 남자 환자가 객혈을 주소로 입워하여 우축 상엽 편평상피세로 폐암으로 진단 받았다. 캄퓨터 단층촬영상 하부 기관에 종양의 침윤이 의심되었다. 우측 하엽과 중엽을 보존하기 위해서 우측상엽과 하부 기관외측을 포함하여 절제하는 기관기관지 성형술 시행하였고, 수술후 우측 폐의 팽창은 완전하였다. 수술 후 1주일째 시행한 기관지 내시경 검사상 우측 중엽과 하엽의 기관지는 뒤틀림 없이 잘 유지되어 있었다. 수술 후 항암치료와 방사선 치료를 받고 현재 환자는 수술 후 1년 7개월 동안 외래 추적관찰 중이다. 저자들은 우측 상엽의 폐암이 기관 하부를 침범한 경우에 우측 기관 소매 전폐절제술의 합병증을 피하고 환자의 폐기능을 보조하면서 침윤된 우측상엽을 포함하여 절제하는 기관기관지 성형술을 시행하여 이에 보고하는 바이다.

Phyllodes tumor of the breast, especially malignant, is a rare tumor which has characteristic cytologic features. We recently experienced a case of fine needle aspiration cytology of malignant phyllodes tumor of the breast metastatic to the lung. The aspirate showed cellular smear with biphasic population of epithelial and stromal cells. Many individual large cells with round hyperchromatic nuclei were found in the necrotic background and stromal cell atypia was also present. Chondrosarcomatous fragments were also seen in cytologic specimens.

Cytologic features of inflammatory pseudotumor of the lung have not been described frequently. We report fine needle aspiration cytologic(FNAC) finding of a case of inflammatory pseudotumor misdiagnosed as adenocarcinoma in a 63-year-old man. The FNAC displayed a mixture of histiocytes, myofibroblasts, pneumocytes, and plasma cells. Some histiocytes and myofibroblasts had large nuclei with irregular nuclear membrane and prominent nucleoli, which mislead the diagnosis on adenocarcinoma on FNAC. The heterogeneous cell population is the unique cytologic features of inflammatory pseudotumor, which are helpful to distinguish it from other circumscribed benign and malignant lesions. Familiarity with these features is essential to avoid misdiagnosis and possible overtreatment.

종격동내의 림프계는 해부학적으로 크게 3구역 즉, anterior compartment, visceral compartment, 그리고 paravertebral sulci 로 나눌 수 있으며, 이 중 식도와 폐로부터 유입되는 visceral compartment가 종양외과학적으로 중요한 의미를 가지고 있다. 두경부 암종에서도 경부의 림프계를 거쳐 종격동의 visceral compartment의 림프계로 전이가 일어날 수 있는데, 본 연제에서는 종격동의 visceral compartment와 관련이 깊은 식도 림프계의 해부학적인 특성과 종격 림프계의 해부, 그리고 두경부 암종의 수술에서 종격 림프절 적출에 대하여 기술하였다. 선천성과 악성 질환에 의한 경우는 비악성 질환에 의한 경우와 치료방침에 많은 차이가 있어 비악성 질환에 의한 기관식도루에 초점을 두고 논하고자 한다.

Congenital bronchial atresia is a rare anomaly, which results from a congenital focal obliteration of a proximal segmental or subsegmental bronchus, with normal development of the distal structures. The short atretic segment leads to the accumulation of mucus within the distal bronchi, forming a bronchocele and air trapping of the alveoli supplied by these bronchi. The diagnostic CT features include the presence of a branching opacity and the bronchocele, which radiate from the hilum and are surrounded by an area of hyperlucency.

The lungs are one of the most common visceral sites for metastatic disease. The identification of a metastasis from a second primary lung tumor is clinically important for patients with pulmonary metastases of an extrathoracic origin. Although the cytologic features of metastatic tumors involving the lung have been extensively described, making the cytologic diagnosis is usually not easy in the absence of clinical information. However, the immunohistochemical staining for many tumor markers and the different expressions of cytokeratin 7 and 20 are very useful in the diagnosis. This review presents the cytomorphological spectrum of metastatic tumors along with the immunohistochemical findings.
