  • 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.

  • Epithelial-myoepithelial carcinoma (EMC) of lung is a minor subset of salivary type carcinoma of lung of known low grade malignancy. Histologically, two-cell components forming duct-like structure with inner epithelial cell layer and outer myoepithelial cell layer are characteristics of EMC. In salivary gland, dedifferentiation of conventional low grade malignancy has been reported and is thought to be related with poor prognosis. However, precise histomorphology and prognostic factors of pulmonary EMC have not been clarified due to its rarity. Herein, we reported a rare case of EMC presented as endobronchial mass in a 53-year old woman, which showed predominant solid lobular growth pattern and lymph node metastases.

  • Over the past few years, video-assisted thoracic surgery [VATS] has been used increasingly for intrathoracic pathologic problems as a less invasive operative techniques. Today it is viewed as a sparing and safe alternative to thoracotomy for a wide spectrum of indications. Using video-assisted operative thoracoscopy, we performed consecutive 150 operations on 148 patients during the initial 2 years of our experience from July 1992 with the following indications: pneumothorax [n=53], hyperhidrosis [n=29], mediastinal mass [n=23], pleural disease [n=13], diffuse parenchymal or interstitial lung disease [n=12], benign pulmonary nodule [n=7], metastatic lung mass [n=3], primary lung cancer [n=3], bronchiectasis [n=2], malignant pericardial effusion [n=2], endobronchial tuberculosis [n=1], esophageal achalasia [n=1], and pulmonary parenchymal foreign body [n=1]. There were no death, and overall complicaton rate was 24.0%[n=36]. The most prevalent complication was persistent air leakage [longer than 5 days] in 14 cases [9.3%]. Persistent pleural effusion [longer than 5 days] occurred in 6 cases [4.0%]. Six patients were converted to an open thoracotomy because of inability to control the operative bleeding [n=3], failed adhesiolysis in bronchiectasis [n=2], and radical excision of an lung cancer [n=1]. Pneumothorax recurred in 3 cases[2.0%]. Other complications were Horner`s syndrome, diaphragm tears, temporary phrenic nerve palsy, hoarseness, subsegmental atelectasis, transient respiratory difficulty, and esophageal mucosal tear. The advantages of this minimally traumatizing operative technique lie in improved visualization, decreased pain, shortened hospital stay, and less postoperative morbidity. The indications of VATS has been extended increasingly to intrathoracic pathologies, but its role in the managements of primary lung cancer and esophageal disease remains to be defined.

  • 59세의 여자 환자가 반복되는 폐렴 및 흉수를 주소로 내원하였다. 흉부 전산화 단층촬영상 우폐하엽 기저분절에 기관지 확장을 동반한 폐허탈 및 염증성 침윤소견이 관찰되었으며, 기관지내의 종괴소견은 관찰되지 않았다. 굴곡성 기관지경 검사상 우하엽 기저분절 기관지 입구에 점액성의 백색 표면을 보이는 돌출성 종괴가 관찰되었고 관강은 좁아져 있었으며 감자 생김상 세기관지 폐포암으로 확진되었다. 환자는 우하엽 절제술을 시행받았으며 수술후 증상없는 상태로 12개월째 추적관찰중이다. 세기관지 유두종은 극히 드문 양성 폐종양으로 알려져 있고 국내에는 아직 보고된 바가 없어 문헌 고찰과 함께 보고하는 바이다.

  • Background: Bronchoscopy is a useful diagnostic and therapeutic tool. However, the clinical use of high-flow nasal cannula (HFNC) in adults with acute respiratory failure for diagnostic and invasive procedures has not been well evaluated. We present our experiences of well-tolerated diagnostic bronchoscopy as well as cases of improved saturation in hypoxaemic patients after a therapeutic bronchoscopic procedure. Methods: We retrospectively reviewed data of hypoxaemic patients who had undergone bronchoscopy for diagnostic or therapeutic purposes from October 2015 to February 2017. Results: Ten patients (44-75 years of age) were enrolled. The clinical purposes of bronchoscopy were for diagnosis in seven patients and for intervention in three patients. For the diagnoses, we performed bronchoalveolar lavage in six patients. One patient underwent endobronchial ultrasonography with transbronchial needle aspiration of a lymph node to investigate tumour involvement. Patients who underwent bronchoscopy for therapeutic interventions had endobronchial mass or blood clot removal with cryotherapy for bleeding control. The mean saturation ($SpO_2$) of pre-bronchoscopy in room air was 84.1%. The lowest and highest mean saturation with HFNC during the procedure was 95% and 99.4, respectively. The mean saturation in room air post-bronchoscopy was 87.4%, which was 3.3% higher than the mean room air $SpO_2$ pre-bronchoscopy. Seven patients with diagnostic bronchoscopy had no hypoxic event. Three patients with interventional bronchoscopy showed improvement in saturation after the procedure. Bronchoscopy was well tolerated in all 10 cases. Conclusion: This study suggests that the use of HFNC in hypoxaemic patients during diagnostic and therapeutic bronchoscopy procedures has clinical effectiveness.

  • 섬유상피성 용종은 중배엽성 기원의 양성 종양으로, 기관지 내에 생기는 경우는 매우 드물다. 또한 이 종괴는 악성화 가능성이 거의 없어, 최소한의 내시경적 절제술이 치료법으로 추천된다. 기관지내 종괴의 감별 진단에 양성의 섬유상피성 용종이 포함될 수 있음을 염두에 두어 불필요한 외과적 광범위 절제를 방지해야겠다.

  • 환자는 37세 여자로 잦은 심한 기침을 주소로 내원하였다. 수술 전 시행한 흥부 전산화 단층 촬영상좌상엽 기관지 입구부의 폐종양으로 의심되는 종괴가 발견되었다. 좌상엽 기관지를 거의 완전히 막고 있는 종괴의 기관지 내시경을 통한 조직 생검 결과는 육아조직을 포함한 만성염증 소견을 보였다. 수술적 절제를 시행하였으며 좌상엽 절제술 후 기관지 절단면의 종양 조직 침범 소견이 보여 소매절제술을 시행하였다. 절제된 종양의 수술 후 조직학적 소견은 원발성 폐부신경절종의 특징을 보였다. 부신경절종은 교감신경절에서 발생하는 종양으로 폐의 실질에서 발생하는 원발성 폐부신경절은 매우 희귀한 질병이다. 이에 저자들은 소매절제술을 시행하여 좋은 결과를 얻었기에 치험 결과를 보고 하는 바이다.

  • 과립 세포종은 흔치않은 양성 종양으로 주로 피부, 혀, 유방에 생기는 것으로 알려져 있다. 이 종양은 각기 다른 장기에 동시 다발적으로도 생길 수 있으며, 한 장기에 여러 군데 생기기도 하는 것으로 알려져 있다. 기관지 계통에서의 빈도는 잘 알려져 있지 않으며, 폐에 발생할 확률은 현재까지 보고된 증례가 약 100예에 지나지 않을 정도로 드문 질환으로 알려져 있다. 폐렴증상을 주소로 33세의 남자환자가 내원 후 기관지 내시경 검사에서 기관지 내 종양이 발견되어 실시한 조직검사상 과립 세포종으로 확인되었다. 환자는 좌측 주 기관지 절개 후 종양 적출술을 받은 다음 기관지 단-단 봉합술을 받았다. 퇴원 후 현재까지 특별한 재발의 징후 없이 1년째 외래 추적 관찰 중이다.
