미분화성 다형성 육종은 중간엽조직에서 기원하는 고등급의 연조직 육종이다. 소장에서 기원한 미분화성 다형성 육종은 매우 드물며 산발적인 증례 보고가 대부분이다. 소장 미분화성 다형성 육종의 증상은 대개는 비특이적이며, 일부에서는 장중첩증으로 발현되어 간헐적 복통을 일으키기도 한다. 미분화성 다형성 육종은 공격적인 성장을 보이는 종양으로 진단 당시에 원격 전이를 동반한 경우가 많다. 가장 흔한 원격 전이 부위는 복막이며, 그 외에도 임파선, 복강 내 고형 장기, 폐나 뇌 등으로 전이할 수 있다. 저자들이 아는 한도에서는, 기관지 내 전이는 현재까지 보고된 바 없다. 저자들은 장중첩증으로 발현한 소장의 미분화성 다형성 육종이 기관지 내로 전이한 드문 증례를 경험하였기에 이를 보고하고자 한다.

A 61-year-old woman came to the hospital with dyspnea and pleural effusion on chest radiography. She underwent repeated thoracentesis, transbronchial lung biopsy, bronchoalveolar lavage, and thoracoscopic pleural biopsy with talc pleurodesis, but diagnosis of her was uncertain. Positron emission tomography showed multiple lymphadenopathies, so she underwent endobronchial ultrasound-guided transbronchial needle aspiration of mediastinal lymph nodes. Here, we report a case of malignant pleural mesothelioma that was eventually diagnosed by endobronchial ultrasound-guided transbronchial needle aspiration. This is an unusual and first case in Korea.

A 62-year-old man with a chronic cough presented with atelectasis of the left upper lobe on chest X-ray. Chest computed tomography showed an atelectasis in the left upper lobe with bronchial wall thickening, stenosis, dilatation, and mucoid impaction. We performed bronchoscopy and found a well-circumscribed mass on the left upper lobe bronchus. The mass was removed by flexible bronchoscopy using an electrosurgical snare and diagnosed with lipoma. An endobronchial lipoma is a rare benign tumor that can be treated by a surgical or endoscopic approach. We report the successful removal of endobronchial lipoma via flexible bronchoscopic electrosurgical snare.

Melanoma can occur as a metastasis within subcutaneous tissue, lymph nodes, or viscera without a detectable primary tumor. Among patients with metastatic melanoma of unknown primary lesion, those with endobronchial metastasis are exceedingly rare. Herein we report a case of an endobronchial and pulmonary metastasis in a patient with melanoma originating from an unknown primary site. The patient without a previous history of melanoma presented with blood-tinged sputum. Fiberoptic bronchoscopy revealed a black polypoid tumor obstructing the posterior basal segmental bronchus of the right lower lobe. A final diagnosis of the malignant melanoma was made based on an immunohistochemical study of the bronchoscopic biopsy specimen. Skin, ophthalmic, oral, and nasal examinations failed to identify occult primary lesions. Subsequent evaluation including positron emission tomography/computed tomography scans did not uncover any abnormalities other than the metastatic pulmonary melanoma. We also describe the characteristic bronchoscopic features of melanoma.

In 1904, Albrecht first used the term "hamartoma" to refer to a congenital abnormal mixing of the normal components of an organ and is applied also to tumors found in many organs other than the lung. Though the term "hamartoma" of the lung have been used with the connection to the presence of cartilage, tumors that do not contain cartilagenous compont is also considered hamartoma. The authors experienced one case of endobronchial hamartoma. The patient, a 42-year-old woman, a teacher in a primary school, was admitted to our hospital with frequent attacks of hemoptysis. Bronchogram on the left disclosed abrupt blocking of bronchial filling at the bifurcation between postero-basal and lateral basal segmental bronchial substantiating a mass in the bronchial lumen. Left lower lobectomy was performed. The answer of pathology was benign endobronchial hamartoma. Postoperative course was uneventful. Discharged on 19th postoperative day.

The origin of hamartoma from the Greek words for "error" and "tumor" is credited to Albrecht who in 1904 described a disorganized arrangement of tissues normally present in an organ and applied also to tumors found in many organs other than the lung. The hamartoma is the most common benign tumor of the lung and revealed accidentally as asymptomatic coin lesion on routine chest X-ray, but the incidence is very low and especially endobronchial origin extremely low. We have been successful surgical experienced one case of a 36-year-old female having endobronchial hamartoma, 4x2.Sx2 cm in size and located at right main bronchial lumen near the carina, which consists of a hard, nodular surfaced mass and adhered to the cartilaginous portion of the right upper lobe bronchus by dense fibrous band and migrate to trachea on expiration or coughing. This case was not suspected by chest X-ray or bronchogram and confirmed bronchoscopy with biopsy. Right pneumonectomy was inevitable because of bronchiectatic change of right bronchus due to tumor obstruction. She was discharged with relatively good general condition on 21 days postoperatively.

Pulmonary mucormycosis is an uncommon opportunistic fungal infection associated with diabetis mellitus, leukemia, lymphoma & other debilitating diseases. Their clinical presentations depend on the associated underlying disorders. Generally patients with leukemia and lymphoma often have rapidly progressive clinical course, and may cause diffuse parenchymal disease refractory to medical and surgical therapies. However, some diabetics with pulmonary mucormycosis have a striking tendency to develop a localized endobronchial disease in major airway which is amenable to therapy with surgery and Amphotericin B. We have experienced a case of endobronchial mucormycosis complicating lung abscess associated with diabetic ketoacidosis, which was cured without specific antifungal therapy or surgery. A brief review of the literature was given.

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.

The prevalence of lung diseases caused by nontuberculous mycobacteria (NTM) is increasing worldwide. Unlike pulmonary tuberculosis, endobronchial NTM diseases are very rare with the majority of cases reported in patients with human immunodeficiency virus infection and acquired immune deficiency syndrome. We reported a rare case of endobronchial Mycobacterium avium disease associated with lobar atelectasis in a young immunocompetent patient and reviewed the relevant literature.
