Pulmonary hamartoma is a common benign tumor of the lung, but endobronchial hamartoma is a rare tumor. Although bronchoscopic rcemoval or removal by bronchotomy or sleeve resection with preservation of the lung may be possible, when irreversible lung damage has occurred because of chronic obstruction and pneumonitis, pulmonary resection may be indicated. We herein report a case of endobronchial hamartoma which was treated by left upper lobectomy. A 42-year-old female with 3-week history of cough and left chest pain visited our hospital. Bronchoscopy showed total occlusion of the orifice of the left upper lobe bronchus by a lobulated endobronchial tumor and bronchoscopic biopsy was failed due to bleeding. A left upper lobectomy was performed because of severe consolidation of the left upper lobe by chronic obstruction. The patient was discharged on postoperative 14th day.

Necrotizing bronchial aspergillosis usually occurs in the immumocompromised host. Aspergillus invades bronchial epithelium and forms endobronchial mass or endobronchial stenosis. A 78-year-old male patient with diabetus mellitus complaining of dyspnea and cough was admitted to our hospital. Plain chest X-ray and chest computed tomogram showed a large endobronchial mass and total collapse of left upper lobe of the lung. Bronchoscopic biopsy of the endobronchial mass revealed chronic inflammation. To confirm the endobronchial mass, we performed sleeve lobectomy of left upper lobe of the lung. Histologically the mass was diagnosed as necrotizing bronchial aspergillosis. We report a case of necrotizing bronchial aspergillosis in an elderly man who has diabetus mellitus with review of the literature.

The remaining lung infarction is a rare but life-threatening complication after a thoracic operation and trauma. We report a case of this rare complication after the left upper lobectomy due to pulmonary aspergilloma. The infarction of the remaining left lower lobe occurred due to kinking of the pulmonary vessels after the left upper lobectomy and the completion pneumonectomy was performed in the post-operative second day. Therefore, prompt diagnosis and treatment may be necessary to prevent morbidity and mortality associated with pulmonary infarction from torsion of pulmonary artery and vein.

Since sclerosing hemangioma of the lung was first described by Liebow and Hubbell in 1956, there have been several reports on cases occurring as a solitary nodule; however, sclerosing hemangiomas occurring as multiple nodules are extremely rare. The histogenesis of this tumor remains controversial and there are several hypotheses of the etiology. Three separate nodules were found in a 57-year-old housewife, one found in the right middle lobe, one in the apicoposterior segment of the left upper lobe, and one in the superior segment of the left lower lobe. The only symptom or sign presented was a dry cough. Apicoposterior segmentectomy of the left upper lobe and wedge resection of the superior segment of the left lower lobe were performed. The postoperative course was uneventful and the patient was discharged on the postoperative 15th day.

In comparison to parenchymal hamartoma, endobronchial hamartoma is rare benign neoplasm of the lung. Most parenchymal hamariomas are asymptomatic and are found incidentally. However, endobronchial hamartomas are frequently discovered through respiratory symptoms as a result of bronchial irritation or obstruction. A 47-year-old male patient was admitted to our hospital due to dry cough f month prior to admission. On bronchoscopic examination, a polypoid mass was found completely obliterating the anterior segmental bronchus of the left upper lobe. We report a case of endobronchial chondroid hamartoma, which was resected by anterior segmentectomy of the left upper lobe.

Epithelioid hemangioendothelioma (HE) is a very rare malignant tumor that is pathologically benign tumor originating from endothelial cell but clinically presents metastasis and recurrence. A 29-year-old asymptomatic man, preoperatively diagnosed as lung cancer in the left lower lung, underwent a lobectomy, a wedge lung resection of left upper lung, and partial resection of diaphragm. Left lower lobar lesion was confirmed as pulmonary epithelioid hemangioendothelioma, but the lesions of the left upper lung and diaphragm were remained calcified by spontaneous regression of HE. We report a case of subcutaneous metastasis that occurred two times at 10 months and 19 months after previous surgical treatment of pulmonary EH.

A 69-year-old man was admitted due to blood-tinged sputum. The preoperative examination revealed 5${\times}$2.8cm sized nodular mass on left upper lobe of the lung. The patient underwent left upper lobectomy and radical Iymph node dissection under impression of lung cancer. Postoperative pathologic examination revealed as primary choriocarcinoma of the lung. The patient expired at postoperative 58 days despite meticulous postoperative care. We planned on immediate adjuvant chemotherapy but was delayed due to postoperative pneumonia and the choriocarcinoma progressed rapidly. Primary choriocarcinoma is an extremely rare clinical entity in lung cancer with no established therapeutic guidelines available. We report a case of the primary pulmonary choriocarcinoma which was diagnosed postoperatively.

Background: To clarify the clinical significance of the aortic nodes in resected non-small cell lung cancer of the left upper lobe. Material and Method: One hundred fifty six patients with resected non-small cell lung cancer of the left upper lobe were studied. Patients who received preoperative induction therapy, non-curative operation or defined as operative mortality were excluded from this study. Result: In N2 left upper lobe tumors, aortic nodes comprised 52.7% of the metastatic mediastinal lymph nodes. In single station N2 disease, a frequently metastasized station was aortic node (64.3%). 5-year actuarial survival according to the N status was 65.0% in N0, 30.4% in N1, and 17.9% in N2. There was no statistically significant difference in survival between N1 and N2 diseases (p=0.06). The patients with metastasis to aortic node alone had a comparatively good prognosis (5-year survival: 35.6%) than other N2 diseases (5-year survival: 4.6%) (p=0.01) and had a similar survival outcome as N1 diseases (p=0.97). Considering the aortic node as N1 node, 5-year survival according to the N status was 65.0% in N0, 31.2% in N1, 4.6% in N2 and significant survival difference was observed between N1 and N2 disease (p=0.00). In multivariate analysis, the male sex (hazard ratio 6.892, p=0.011) and the involvement to the aortic node alone (hazards ratio 2.799, p=0.009) were the significant factors affecting postoperative survival. Conclusion: According to the our data, involvement to the aortic node alone in left upper lobe tumors should be grouped with N1 disease because this combined category reflects the surgical outcome more accurately.

We describe the case of primary pulmonary paraganglioma in a 37-year-old woman who presented recurrent, severe cough. Computed tomography revealed a lobulated inhomogeneous enhanced mass with endobronchial protruding lesion suspected to be lung neoplasm, located in the upper lobe of the left lung. Bronchoscopic biopsy showed chronic inflammation with granulation tissue which was not in accord with the radiologic findings. Subsequently, a left lower sleeve lobectomy was peformed. Histological analysis of the resected tumor proved to be compatible with pulmonary paraganglioma. Primary pulmonary paragangliomas are very uncommon tumors. So we report this case with literature review.

WDFA(Well-differentiated fetal adenocarcinoma) histologically resembles pulmonary blastoma. It is also thought to be a subtype of pulmonary blastoma, which has differentiated epithelial features resembling the fetal lung among its epithelial features and sarcomatous features. We recently encounted a patient who underwent surgery for WDFA. A 19-year-old man had a mass shadow in the upper lobe of the left lung. The tumor was diagnosed as pulmonary blastoma as a result of fine needle aspiration biopsy, and left upper lobe lobectomy was performed. No sarcomatous features was observed on postoperative histologic assessment, and the patient was diagnosed as having WDFA. This case is reported with a discussion of the literatures.
