Primary lung cancer has increased markedly in its incidence and prevalence rate recently in Korea. In frequency, it occupies the second rank cancer preceded by stomach cancer in korean male. From February 1986 to December 1992, we have operated on 55 cases of primary lung cancer in Korea Veterans Hospital and followed them. The results are as follows; 1. The peak incidence of age of primary lung cancer was 6th decade and 5th decade and those were 87.3% of study group, mainly in male. 2. Symptoms were cough [63.6%], dyspnea [41.8%], chest pain and discomfort [38.2%], blood tinged sputum and hemoptysis [21.8%]. Symptoms were frequently encountered before hospitalization and asymptomatic cases were 9.1% of study group. 3. Methods of diagnostic confirmation were bronchoscopic biopsy [52.7%], percutaneous needle aspiration[PCNA][21.8%], sputum cytolgy [12.7%], open biopsy [12.7%]. 4. Histopathologically, squamous cell carcinoma [76.4%] was the most frequent cancer and adenocarcinoma [10.9%], giant cell cancer [7.3%], and the others in order. 5. Methods of operation were pneumonectomy [32.7%], bilobectomy [18.2%], lobectomy [27.3%], lobectomy and segmenectomy [1.8%], exploration [20%], and overall resectability was 80%. 6. Operative mortality was 5.5% [3 cases] and there were 5 cases of complication. 7. Postoperative long-term follow up reveals that the cumulative survival rates in 6 months, 12 months, 26 months, 34 months, 43 months, 64 months were 89.5%, 71.7%, 66.7%, 57.2%, 50.8%, 42.3% respecively.

Pulmonary lymphangiomyomatosis is rare but extremely interesting condition caused by progressive widespread smooth muscle proliferation in the perilymphatic regions throughout the lungs. The patient was a 25-year-old female. She had angiofibromas in the face, and angiomyolipoma in the left kidney which was removed 5 years earlier. Three years ago she started having severe dyspnea with bilateral pneumothoraces. Treatment was initiated with bilateral closed thoracotomies followed by open thoracotomy through median sternotomy and lung biopsy, which revealed the diagnosis of pulmonary lymphangiomyomatosis. Recurrence of pneumothorax was treated by repeated chemical pleurodesis with tetracycline. She has been in good condition during medroxyprogesterone administration for 3 years.

배경: 흉부전산화단층촬영이 보편화되면서 기존의 단순흉부촬영에서는 발견되지 않았던 작은 폐결절이 발견되는 경우가 많아졌다. 이렇게 발견된 폐결절중 크기가 작거나 폐실질 내부에 위치한 결절은 육안 및 촉진으로 확인이 어려운 경우가 많아 생검을 시행하는데 어려움이 따른다. 본원에서는 흉부 전산화단층촬영 유도하에 Hook wire를 사용하여 위치선정을 시행한 후 흉강경하 폐쐐기절제술을 시행하였다. 대상 및 방법: 2006년 12월부터 2010년 6월까지 31명의 환자(남자 17명, 여자 14명)에서 34개의 폐결절을 대상으로 흉부전산화단층촬영 유도 하에 Hook wire를 사용하여 위치선정을 한 후, 흉강경하 폐쐐기절제술을 시행하였다. Hook wire의 이탈 여부, 개흉술 전환 빈도, 위치선정 후 수술 시작까지의 시간, 수술시간, 수술 후 합병증, 대상 병변의 조직학적 진단 등을 분석하였다. 결과: 34예 중 12예는 간유리 병변이었으며 22예는 고형의 폐결절이었다. 병변 크기의 중앙값은 8 mm (범위: 3~23 mm)였으며 병변 깊이의 중앙값은 12.5 mm (범위 1~34 mm)였다. 위치선정 후 마취 시작까지 걸린 시간의 중앙값은 86.5분(41~473분)이었으며, 수술시간의 중앙값은 103분(25~345분)이었다. 1예에서 wire의 흉강 내 이탈이 있었으나 성공적으로 목표 병변을 절제하였다. 4예에서 흉막유착으로 인해 개흉술을 시행하였다. 그러나 목표 병변을 찾지 못해 개흉술로 전환한 예는 없었다. 조직학적 진단에서 전이성 암이 15예로 가장 많았으며, 원발생 폐암 9예, 비특이적 염증소견 3예, 결핵성 염증소견 2예. 림프절 2예, 활동성 결핵 l예, 비정형 샘 증식증 1예 및 정상폐조직 1예로 보고되었다. 결론: 폐실질 내에 위치한 간유리 음영 및 폐결절의 정확한 조직학적 진단을 위해 본원에서는 흉부전산화단층촬영 유도하 Hook wire를 삽입하여 폐결절의 위치를 선정한 후 폐 생검을 시행하였다. 저자들은 이 방법이 정확하면서 최소침습적이고 합병증 발생 및 진료비 상승을 최소화할 수 있는 유용한 술기라고 생각한다.

Glandular papilloma of the lung is one of three histologic types of solitary endobronchial papillomas. It is known as an uncommon benign neoplasm. No malignant glandular papillomas have been reported. Herein, the first case of granular papilloma with malignant transformation is reported. A 74-year-old man with huge right lung mass extended upper and lower lobe was admitted to the hospital complaining of progressive cough and dyspnea. An open lung biopsy was performed. Microscopically, the tumor showed papillary growth pattern with thick fibrovascular cores. The stroma of the fibrovascular cores shown the infiltration of lymphoplasmacytic cells and proliferation of capillaries. The epithelial cells surrounding the papillary fronds were cilliated columnar cells with focal cellar atypia, and frequent mitoses. Suspicious pleural invasion foci were identified. The Ki-67 labeling index was about 24.3% and p53 labeling index was about 31.7%. Glandular papilloma is known as a benign neoplasm, which is lack of atypia and mitosis. In present case, there were several indications of malignant transformation, such as cellular atypia, frequent mitosis, architectural distortion, and pleural invasion. Pathologists must be aware that glandular papilloma can have a changes of malignant transformation. Further studies about disease behavior and molecular characteristics are needed.

Eighty-four patients with pulmonary metastases from gestational choriocarcinoma were treated at the Catholic Medical Center between August, 1985 and August, 1991. Among these 13 patients underwent thoracotomy with resection of pulmonary lesions and the results obtained were follows. 1] The ages of the patients ranged from 26 to 47 years, with a mean age of 31 years. 2] The frequency of chemotherapy before operation ranged from zero to 46, with a mean frequency of 13.6. 3] Four patients were operated upon for a solitary metastasis of the lung; 6 patients, for unilateral multiple metastases and 3 patients, for bilateral pulmonary metastases. 4] Eight patients underwent wedge resection; 1 patient, segmentectomy; 2 patients, lobectomy; 3 patients, open lung biopsy. The lung lesions of eleven patients showed hemorrhagic necrosis[among these, 2 patients combined with pulmonary tuberculosis]; one was non-necrotic choriocarcinoma; another one was metastatic lung carcinoma from endocrine cancer of unknown origin. 5] Among twelve patients who had managed with chemotherapy before thoracotomy three patients were in remission; among 13 patients who had undergone thoracotomy 6 patients were in remission. 6] The median survival time of these patients was 25.8 months with 3 postoperative deaths. Subsequently, in the patients with pulmonary metastases from choriocarcinoma, if the primary tumor is under control, there are no other metastases, and the patients should be able to tolerate the planned operation, it is necessary to undergo aggressive thoracotomy for diagnostic purposes; for therapeutic purposes only when the pulmonary lesion is the only remaining source of increased hCG excretion; for reduction of tumor volume to shorten hospitalization or to reduce the quantity of drugs.

The malignant fibrous histiocytoma was the most common soft tissue sarcoma in late life adult. It was first described in 1964 by 0' Brien and Stout. It's histiogenesis had been considered to be of histiocytic origin. It Involves the extremities, retroperitoneum and trunk. It usually metastasizes to the lung. but primary lung lesion is extremly rare and it's prognosis was poor. We have experienced a case of MFR, which was confirmed by open lung biopsy. So we report a case of MFR of the lung with review of literature.

Nodular lymphoid hyperplasia (NLH) is a benign lymphoproliferative disease that can affect the lung. Because of its rarity, little is known about the etiology and natural history of NLH. Most cases are usually asymptomatic and found incidentally on imaging studies. Imaging finding of NLH has shown most commonly as a solitary lesion, although multifocal pulmonary nodules may be seen. Surgical resection has proved curative in the cases previously described. We report a rare case of NLH in a 55 year-old man who presented with bilateral multiple pulmonary nodules on chest radiography. Open biopsy was performed from the upper and lower lobe of the left lung. The lesions were pathologically diagnosed as pulmonary NLH. Multifocal residual nodules in both lungs remain stable without spontaneous regression during the 3 years of follow-up.

Pulmonary alveolar proteinosis(PAP) is a rare disease in which the alveolar spaces are filled with an eosinophilic, PAS-positive material, whereas the interstitial architecture of the lung usually remains unaffected. Although a definitive diagnosis is usually made by an open lung biopsy, bronchoalveolar lavage(BAL) cytology may play a decisive role in the diagnosis and therapy of these patients and may spare a patient a more invasive diagnostic procedure. The author presents a patient in whom BAL cytology specimen contained the characteristic globules of amorphous proteinaceous PAS-positive material accompanied by background of rare macrophages and inflammatory cells. Ultrastructural study using BAL specimen can confirm the diagnosis of PAP.
