A chest x-ray of 68 year old male showed pneumonic consolidation of right lower lung field with blunting of right cardiac border. Computerized tomography of chest revealed infiltrative mass with V-shaped calcification just below right main bronchus. This finding has to be made into differential diagnosis of numerous pulmonary diseases including, mycobacterial disease, neoplasm, lymphadenopathies, and foreign bodies. Initial bronchoscopic findings suggest endobronchial mass lesion on right intermediate bronchus but endobronchial biopsy fail to prove malignant cell or underlying illness. But repeated endobronchial biopsy shows metallic material in the right Intermediate bronchus and we remove it with alligator jaws forcep under bronchoscopy. He was well after discharge.

Mucoepidermoid tumor arising from the bronchial tree as one of the bronchial adenoma is a extremely rare in incidence. And its clinical and histopathologic behavior has been reported as varying degree of benign to extremely malignant. Because symptoms are usually related to the bronchial obstruction or obstructive pneumonitis followed by endobronchial growth of tumor, frequently error is made in diagnosis of this tumor as entity of obstructive lung disease. We present a case of mucoepidermoid tumor with review of relevant literatures arising from the right middle lobe bronchus extending to intermediate bronchus in 47 years old housewife and was surgically removed by middle and lower Iobectomy.

Mucoepidermoid carcinoma arising in the tracheobronchial tree is an extremely rare tumor. Usually it remains as locally invasive neoplasm, although malignant change is described. Histologically, it is characterized by an admixture of vacuolated, mucus producing cells and sheets of epithelial cells with a cohesive pattern which resemble squamous cells. Its clinical and histopathological behaviors were reported as varying degrees of benign to extremely malignant. We had experienced two young patients with low-grade mucoepidermoid carcinoma of the right and left upper lobar bronchi. A 15-year-old man who had had intermittent hemoptysis for 1 year underwent right upper lobectomy. And the other 18-year-old man had suffered from obstructive pneumonitis for 6 months underwent left pneumonectomy. The postoperative courses were uneventful, and the bronchoscopy and chest CT which were done at 6 months later revealed no regional recurrence.

Occult bronchial foreign body is that long-standing foreign body lodge in bronchial tree. Occult bronchial foreign bodies arc rare in adults, whereas tracheobronchial aspiration of foreign bodies occurs commonly in children. A 65-year-old man with chronic cough, sputum production, and fever was transferred for treatment of right middle and lower lobc collapse and obstructive pneumonitis as evidenced by imaging studies. The patient was treated with right middle-lower bilobectomy because fiberoptic bronchoscopic removal of the foreign body failed. We report this case with review of literatures.

Background: The objective of this research is the computed axial tomography (CT) imaging grading of radiation induced pneumonitis (RP) and its correlation with clinical and radiotherapeutic parameters. Materials and Methods: The chest CT films of 20 patients with non-small cell lung cancer who have undergone threedimensional conformal radiation therapy were reviewed. The proposed CT grading of RP is supported on solely radiological diagnosis criteria and distinguishes five grades. The manifestation of RP was also correlated with any positive pre-existing chronic obstructive pulmonary disease (COPD) history, smoking history, the FEV1 value, and the dosimetric variable V20. Results: The CT grading of RP was as follows: 3 patients (15%) presented with ground glass opacity (grade 1), 9 patients (45%) were classified as grade 2, 7 patients (35%) presented with focal consolidation, with or without elements of fibrosis (grade 3), and only one patient (5%) presented with opacity with accompanying atelectasis and loss of pulmonary volume (grade 4). Both univariate and multivariate analysis revealed as prognostic factors for the radiological grading of RP the reduction of FEV1 and the V20 (P=0.026 and P=0.003, respectively). There was also a significant (P<0.001) correlation of radiological grading of RP with FEV1 and V20 (spearman rho 0.92 and 0.93, respectively). Conclusions: The high correlation of the proposed radiological grading with the FEV1 and the V20 is giving a satisfactory clinical validity. Although the proposed grading scale seems relevant to clinical practice, further studies are needed for the confirmation of its validity and reliability.

Benign endobronchial tumors are rare diseases with an incidenced of between 1 and 5% of all Jung tumors. An endobronchial fibroepithelial polyp is an extremely rare form of benign bronchial tumor. Clinically, an endobronchial fibroepithelial polyp causes an airway obstruction and obstructive pneumonitis as does other endobronchial tumors. Therefore, it is important to differentiate an endobronchial fibroepithelial polyp pathologically from other benign endobronchial tumors and bronchogenic carcinomas. Here, we report a case of an endobronchial fibroepithelial polyp, in a 25-year-old man who had suffered from chest discomfort upon deep breathing with a brief review of the relevant literature.

48세 남자와 46세 여자 환자가 기관지 결석증과 페쇄성 폐렴으로 내원하였다. 기관지 내시경을 이용한 기관지 결석 제거를 시도하였으나 실패 후 개흉술을 통한 폐중엽 절제 수술을 시행 받았다. 병리학적 검사상 기관지 결석증을 동반한 흥부 방선균증으로 진단되었다. 기관지 결석증을 동반한 기관지 흉부 방선균증은 매우 드물게 발생되는 것으로 저자들은 이를 치험하였기에 보고하는 바이다.

성인에서의 잠복 기관지 이물은 소아의 기관지내 이물 흡인과 달리 매우 드물며 아직까지 기관지나 폐의 연관손상 정도와 잠복기간에 따른 치료전략이 정립되어 있지 않은 상태다. 과거력상 반복적인 기침과 객담, 발열을 경험하였으나 30년 전에 사인펜 뚜껑이 기도내로 흡인되었던 사실을 인지하지 못하던 40세 남자 환자가 동일 주소와 영상검사상 우중엽 및 하엽의 허탈과 폐쇄성 폐간질염 소견으로 전원되었다. 처음엔 기관지경 이물 제거와 내과적 치료를 계획하였으나 제거가 불가능하였고 결국 개흉후 양엽 절제를 통해 치료하였다. 저자들은 본 증례가 잠복성 기관지 이물의 다양한 임상상 축적에 중요한 정보를 제공하였다고 생각한다.
