Endobronchial inflammatory myofibroblastic tumor is a rare primary lung disease. A 39-year-old woman with dyspnea and a productive cough underwent complete surgical resection of a small-sized inflammatory myofibroblastic tumor that invaded the left main bronchus and the carina with lung-saving modified left one-stoma-type carinoplasty. We report this case with a review of literature.

Pulmonary hamartoma is relatively common among the benign tumors of lung, and is credited to Albrecht who In 1904 described a disorganized arrangement of tissue normally present In an organ. But hamartoma has rare incidence of total pulmonary tumors, and especially endobronchial origin is extremely rare. We have experienced three cases of pulmonary hamartoma Including one bronchial origin. First case was a 27 years old woman who had multiple hamartomas, located all in right middle lobe and middle lobectomy was performed. Second case, a 56 years old woman, had endobronchial hamartoma, l x l .5x l .8cm in size and located at right intermediate bronchus. Right pneumonectomy was Inevitable because of It`s proximal location near the hilum. Third case, a 55 years old man, revealed sclerosing hemangioma microscopically, 4x4x5 cm In size, in right lower lobe and right lower lobectomy was performed. Postoperative course of all of them were uneventful and discharged with good general condition on the ~ 4th to 26th day postoperatively.

Acute airway obstruction after hemoptysis occurs due to the presence of blood clots. These conditions may result in lifethreatening ventilation impairment. We report a case of obstruction of the large airway by endobronchial blood clots which were removed using bronchoscopic cryotherapy at the bedside of intensive care unit. A 66-year-old female with endometrial cancer who had undergone chemotherapy, was admitted to the intensive care unit due to neutropenic fever. During mechanical ventilation, the minute ventilation dropped to inadequately low levels and chest radiography showed complete opacification of the left hemithorax. Flexible bronchoscopy revealed large blood clots obstructing the proximal left main bronchus. After unsuccessful attempts to remove the clots with bronchial lavage and forceps extraction, blood clots were removed using bronchoscopic cryotherapy. This report shows that cryotherapy via flexible bronchoscopy at the bedside in the intensive of intensive care unit is a simple and effective alternative for the removal of endobronchial blood clots.

호지킨병이 기관지내 종물의 형태를 띠는 경우는 매우 드문 것으로 보고되고 있다. 저자들은 호흡곤란을 호소하면서 흉부방사선 촬영 소견상 우중하엽 무기폐를 보였던 23세 남자 환자에게서 기관지내시경을 시행하여 우측 주기관지를 막고 있는 용종형 종괴를 발견하고 기관지내시경하 생검을 시행한 결과 호지킨병 중에서 결절성 경화형으로 진단하여 전신 항암요법을 시행한 결과 증세호전 및 병변의 소실을 보였기에 문헌고찰과 함께 보고하는 바이다.

폐실질에 존재하는 결핵종의 경우 정해진 기간동안 치료하면 크기가 감소하지 않더라도 치료를 종료하고 다시 조직검사를 시행하지 않는 경우가 일반적이어서 치료 중 결핵종 내의 조직 소견의 변화를 평가한 보고가 국내에서는 없는 실정이다. 이에 저자들은 세균학적 및 조직학적으로 확진된 종양형 기관지결핵에서 치료 중 반복적으로 기관지내시경 검사 및 조직검사를 시행하여 치료반응을 평가한 예로, 15개월 간의 치료에도 불구하고 육안적으로 종괴가 관찰되고 조직소견상 만성육아종성염증이 지속되었으나 치료 종료 후 자연적으로 기관지내 종괴가 소멸된 환자를 경험하였기에 이를 보고하는 바이다.

Aspergillus causes a variety of clinical syndromes in the lung including tracheobronchial aspergillosis, invasive aspergillosis, chronic necrotizing pulmonary aspergillosis, allergic bronchopulmonary aspergillosis, and aspergilloma. Aspergilloma usually results from ingrowths of colonized Aspergillus in damaged bronchial tree, pulmonary cyst or cavities of patients with underlying lung diseases. There are a few reports on endobronchial aspergilloma without underlying pulmonary lesion. We have experienced a case of endobronchial aspergilloma associated with foreign body developed in an immunocompetent patient without underlying lung diseases. A 59-year-old man is being hospitalized with recurring hemoptysis for 5 months. X-ray and computed tomography scans of chest showed a nodular opacity in superior segment of left lower lobe. Fiberoptic bronchoscopy revealed an irregular, mass-like, brownish material which totally obstructed the sub-segmental bronchus and a foreign body in superior segmental bronchus of the lower left lobe. Histopathologic examinations of biopsy specimen revealed fungal hyphae, characteristic of Aspergillus species.

This study aims to analyze dose distribution and treatment time of endobronchial brachytherapy (EBBT) by changing the position step size of the dwell position. A solid water phantom and an intraluminal catheter were used in the treatment plan. The treatment plans were generated for 3, 5, 7, and 10 cm treatment lengths, respectively. For each treatment length, the source position step sizes were set as 2.5, 5, and 10 mm. Three reference points were set 1 cm away from the central axis of the catheter, along the axis, for uniform dose distribution. Volumetric dose distribution was calculated to evaluate the dosimetric effect. The total radiation delivery time and total dwell time were estimated for treatment efficiency, which were increased with position step sizes. At half-life time, the differences between the position step sizes in the total radiation delivery time were 18.1, 15.4, 18.0, and 24.0 s for 3, 5, 7, and 10 cm treatment lengths, respectively. The dose distributions were more homogenous by increasing the position step sizes. The dose difference of the reference point was less than 10%. In brachytherapy, this difference can be negligible. For EBBT, the treatment time is the key factor while considering the patient status. To reduce the total treatment time, EBBT can be performed with 2.5 mm position step size.

호흡곤란을 주소로 내원한 42세 여자환자가 단순 흉부 촬영상 좌측 폐의 무기폐 소견을 보였다. 기관지 내시경과 흉부 컴퓨터 단층촬영상 좌측 주기관지에 종괴가 발견되었다. 조직검사상 종괴는 기관지 평활근종으로 진단되었다. 개흉술을 실시하여 좌측 주기관지절개를 하고 종괴를 제거하자 중엽은 정상적으로 환기가 되었다. 또한 하행대동맥에서 좌폐하엽으로 공급되는 이상동맥이 발견되어 좌폐하엽 절제수술을 동시에 실시하였다. 병리검사상 좌폐하엽은 내엽형 폐격리증으로 진단되었다. 저자들은 기관지 평활근종과 내엽형 폐격리증이 공존하는 드문 질환을 치험하였기에 보고하는 바이다.

기관지흉막루는 수술적 치료를 고려해야 하나 대부분의 환자들이 전신상태가 불량하고 기저질환으로 인해 수술을 시행할 수 없는 경우가 많다. 이런 환자들에게 있어서 굴곡성 기관지내시경을 이용하여 누공을 폐쇄시키는 다양한 방법들이 시도되고 있다. 저자들은 폐렴 및 농흉이 동반된 고령의 환자에서 흉관삽입 후 발생한 원위부 기관지 흉막루를 굴곡성 기관지내시경을 이용한 EWS 삽입으로 치료에 성공한 1례가 있어 보고하는 바이다.
