Endobronchial leiomyoma is a rare tumor that accounts for less than 2% of pulmonary benign tumors. A 32 year-old woman was admitted with fever, cough and sputum for a month. She had suffered from intermittent cough over three years. The chest X-ray and chest CT(computed tomography) showed a nodular lesion obstructing the proximal portion of the left lower lobar bronchus and atelectasis of the left lower lobe. Flexible Bronchoscopy detected a mass obstructing the distal portion of the left main bronchus and endobronchial biopsy showed benign smooth muscle cells. There was no abnormal finding in the uterine examination. Therefore this case was diagnosed as primary endobronchial leiomyoma. The lobectomy was performed due to intractable pneumonia and secondary parenchymal destruction. Postoperative course was uneventful and she was discharged in good health.

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.

Purpose: Lymphoma originated from mucosa associated lymphoid tissue(MALT) is most common in gastrointestinal system, and rarely found in salivary gland, thyroid, bronchus or orbit. We experienced a case of MALT lymphoma which was originated from conjunctiva and involving lower eyelid without metastasis. Methods: A 40-year-old man suffered palpable mass on right lower eyelid without pain. Orbital computed tomographic and ultrasonographic findings showed a conical mass($1.9{\times}1.2{\times}0.9cm$ size) inside lower eyelid. The mass was completely excised under local anesthesia and histopathological examination was followed. Results: Microscopic finding showed a multiple follicular colonization. In the follicle, small lymphocytes and plasma cells differentiated to centrocyte-like cell, monocyte B cell, plasma cell were diffusely infiltrated. Immunophenotyping was preformed on fixed section. The majority of the small cells were immunoreactive for the B cell marker CD20. Based on the typical histological findings supported by immunostaining, the mass was defined as MALT lymphoma. After excision, SPECT, abdominal CT was carried out and there were no evidence of extraorbital disease. Conclusion: Biopsy and pathological examination should be performed in patients who complain palpable mass on lower eyelid because of possibility of MALT lymphoma. Although MALT lymphoma is rarely metastasized, it is necessary to evaluate the extraorbital involvement using SPECT or other radiologic exams. For detecting extraorbital involvement, periodic follow-up examination is need.

Leiomyoma of the trachea is a very rare tumor, and the tracheal tumor is frequently misdiagnosed and treated as bronchial asthma. We report here a case of leiomyoma of the trachea which was successfully resected. A 40-year-old woman has sufferred from a repeated episode of asthmatic attack for two years. Intensive therapy for asthma had no beneficial effect on her respiratory symptoms, and wheezing and stridor did not disappear. Chest CT and bronchoscopy revealed a pedunculated mass on the trachea just above the carina. Wedge resection of the trachea and right main stem bronchus including the tumor and end-to-end anastomosis was performed. The result of the pathologic examination of the tumor was tracheal leiomyoma. Her postoperative course was uneventful and postoperative bronchoscopic findings showed clear healing of the anastomosis site.

A 70-year-old man was referred to the department of pulmonology due to blood tinged sputum and an abnormal chest X-ray. The chest X-ray and CT scans revealed a lobulated contour mass-like lesion in the left upper lung field. The bronchoscopic examination showed a whitish and polypoid mass occluding the left upper lobe bronchus. A biopsy specimen from the lesion revealed many aspergillus hyphae. Intravenous and oral itraconozole were administered over a 4 weeks period. Several months later, the size of the mass on chest X-ray increased and a percutaneous lung biopsy revealed a sarcomatoid carcinoma. We reported a case of lung cancer that was obscured by an endobronchial aspergilloma with a review of the relevant literature.

We report on a case of a patient with laryngo-tracheobronchial amyloidosis who complained of cough, sputum, and hoarseness. A chest X-ray showed consolidation in the right middle lobe. A chest CT scan showed diffuse, irregular narrowing of the tracheobronchial tree and atelectasis of the right middle lobe, with calcification of bronchial wall. Bronchoscopic findings were multinodular submucosal thickening of the right vocal cord, and yellowish multinodular submucosal thickening from the lower trachea through both main bronchi, as well as the lingular division of the left upper lobe, the right middle lobe, and the right lower lobe. The right middle lobe bronchus was nearly obstructed. The diagnosis of amyloidosis was made by multiple ronchoscopic biopsies on the right vocal cord and both bronchi. Pathologic findings were characteristic apple-green birefringence under polarized microscopy with Congo-red stain. The patient had no evidence of systemic amyloidosis. The patient is under conservative symptomatic treatment.

A 59-year old female patient was admitted due to massive hemoptysis. 6-months previously, we performed ascending aorta graft interposition for terating Debakey type 1 acute aortic dissection. Chest CT scan showed the fistula between the descending thoracic aorta and the left lower lobe. We performed descending thoracic aorta graft interposition under cardiopulmonary bypass. She recovered well without any postoperative problems. Distal aorto-bronchial fistula after a previous aortic operation is very rare. We report here the good results of treating aorto-bronchial fistula because we recognized this lesion early and performed an early operation.

Primary pulmonary amyloidosis is a rare condition that can be classified into the tracheobronchial, diffuse alveolar septal, and nodular parenchymal type. Tracheobronchial amyloidosis is characterized by deposition of fibrilar proteins in the tracheobronchial tree, and it can be subdivided into diffuse and focal varieties. In this report, a case of diffuse tracheobronchial amyloidosis confirmed by flexible fiberoptic bronchoscopic biopsy is presented. The patient was a 43-year old male with a chief complaint of cough and sputum for 20 days and dyspnea for one day. The chest CT scan showed diffusely thickened walls of both the main and lobar bronchi with calcification. The bronchoscopic findings showed nodular lesions of the trachea, a diffuse bronchial stenosis of both the main bronchi and a pinpoint narrowing of the left upper and right middle lobar bronchus. The biopsy showed submucosal deposits of homogenous eosinophilic amyloid materials and an apple-green birefringence under polarizing microscopy following the Congo-red stain.

An 86 year old woman was admitted complaining of dyspnea and right pleuritic pain with a 5 week durations. A physical examination, chest X-ray, and diagnostic thoracentesis upon admission revealed findings consistent with severe pneumonia and empyema on the right lung. Despite the insertion of a chest tube and negative suction via Emersion pump, the continuous air leakage was sustained, and a bronchopleural fistula (BPF) was found on the chest-CT. A flexible bronchoscopic occlusion with an Endobronchial Watanabe Spigot (EWS) was performed after 56 days of admission. An 5 mm diameter EWS was successfully inserted into the anterior segmental bronchus of the right upper lobe by flexible bronchoscope. There was no aAir leakage detected after this procedure. The patient was discharged 30 days after the EWS occlusion.

A 10-year-old, castrated poodle dog presented with a cough for 2 weeks, and the cough initially developed since very young age. On radiographs, pneumothorax was noticed by characteristics of radiolucent area without pulmonary markings along the thoracic wall and diaphragm, retracted lung lobes from the thoracic wall and severely decreased volume of the left cranial lung lobe with disconnected bronchus. Computed tomography (CT) findings identified several pulmonary air-filled cysts and collapsed lung with abnormal shape and non-tapered end of bronchus, bronchioles at the accessory lobe and left cranial lobe. Also, pneumothorax, pneumomediastinum and subcutaneous emphysema were found. Imaging diagnosis was the spontaneous pneumothorax caused by ruptured emphysematous bullae associated with congenital bronchial cartilage abnormality or bronchial tree malformation. On surgery, hypoplasia of the left cranial lobe, right middle lobe, and accessory lobe with a bulla where air was leaking was identified. The accessory lobe was partially resected and bronchial cartilage hypoplasia was confirmed by histopathologic examination.
