Lung torsion is a very rare event that has been reported in only 9 cases in the pediatric literature but has not yet been reported in Korean infants. We present a case of lung torsion after tracheoesophageal fistula repair in an infant. Bloody secretion from the endotracheal tube and chest radiographs and computed tomographic scan results indicated lung torsion. Emergency exploration indicated $180^{\circ}$ torsion of the right upper lobe (RUL) and right middle lobe (RML). After detorsion of both lobes, some improvement in the RUL color was observed, but the color change in the RML could not be determined. Although viability of the RML could not be proven, pexy was performed for both the lobes. Despite reoperation, clinical signs and symptoms did not improve. The bronchoscopy revealed a patent airway in the RUL but not in the RML. Finally, the RML was surgically removed. The patient was discharged on the 42nd day after birth.

Lymphangioleiomyomatosis (LAM) is a rare, cystic lung disease that is associated with mutation in the tuberous sclerosis genes, renal angiomyolipomas, lymphatic spread and a remarkable female gender predilection. The pathology of LAM is represented by the proliferation of immature smooth muscle cells in the walls of airways, and venules and lymphatic vessels in the lung. The clinical course of LAM is characterized by progressive dyspnea on exertion, recurrent pneumothorax and collections of chylous fluid. The diagnosis of pulmonary LAM can be made on chest X-ray, a high-resolution CT scan and lung biopsy. We experienced a case of pulmonary lymphangioleiomyomatosis in a 28-years-old female patient who had suffered from progressive dyspnea on exertion, so we report on it along with a brief review of the relevant literature.

A 64-year-old male was admitted due to abruptly developed, severe dyspnea via local clinic. He had been a heavy smoker and alcoholic for a long time. Chest PA showed huge haziness in right upper lung field. Sputum culture for bacteriology was positive for Klebsiella pneumoniae. Immediately, appropriate antibiotics were administered and artificial ventilation was started. On 40th hospital day, simple chest roentgenogram taken due to sudden aggravated dyspnea showed marked hyperlucency in right upper lung field, suggestive of rupture of abscess cavity and resultant pneumothorax. At that time, chest tube was inserted but air leakage from the chest tube persisted. Chest CT scan taken after chest tube insertion showed the tube inserted into a thin-walled cavity in the above lesion. on 84th hospital day, right upper lobectomy with decortication was performed. Pathologically, cavittary lung abscess was diagnosed on the findings of partial re-epithelialization of ciliated columnar epithelium with severe pulmonary vascular occlusion and extensive fibrous pleural adhesions.

Multicentric Castleman disease (MCD) is an uncommon systemic lymphoproliferative disorder that may cause multiple organ damage. Castleman disease-associated diffuse parenchymal lung disease (DPLD) has not been well studied. A 32-year-old man was referred to our hospital for progressive generalized weakness, light-headedness, and dyspnea on exertion for more than one year. Laboratory evaluations showed profound anemia, an elevated erythrocyte sedimentation rate, and an increased C-reactive protein level with polyclonal hypergammaglobulinemia. Chest radiography, computed tomography (CT), and positron emission tomography-CT scan demonstrated diffuse lung infiltration with multiple cystic lesions and multiple lymphadenopathy. In addition to these clinical laboratory findings, bone marrow, lung, and lymph node biopsies confirmed the diagnosis of idiopathic MCD (iMCD). Siltuximab, an interleukin-6 inhibitor, and glucocorticoid therapy were initiated. The patient has been tolerating the treatment well and had no disease progression or any complications in 4 years. Herein, we report this case of human herpesvirus-8-negative iMCD-associated DPLD accompanied by multiple cystic lesions, multiple lymphadenopathy, and polyclonal hypergammaglobulinemia with elevated immunoglobulin G (IgG) and IgG4 levels. We recommend a close evaluation of MCD in cases of DPLD with hypergammaglobulinemia.

Pulmonary hypertension may be associated with variable conditions such as the hyperkinetic state or pulmonary vascular obstruction. In these, stenosis of the individual pulmonary veins without any cardiac or vascular malformation is very rare. We experienced stenosis of individual pulmonary veins in a 10 months old boy who was admitted with recurrent dyspnea and cyanosis and then underwent angiogram and a lung perfusion scan.

We report a rare case of lung disease caused by Mycobacterium terrae in a previously healthy woman. A 45-year-old woman was referred to our hospital due to a chronic cough with sputum. A computed tomography scan of the chest revealed bronchiolitis in conjuction with bronchiectasis in both lungs. Nontuberculous mycobacteria were identified and isolated from the bronchoalveolar lavage fluid collected from each lung. All isolates were identified as M. terrae by various molecular methods that characterized the rpoB and hsp65 gene sequences. Antibiotic therapy using clarithromycin, rifampin, and ethambutol improved the patient's condition and successfully resulted in sputum conversion.

We performed thoracoscopic resection for diagnosis in 41 year-old-female presenting with multiple pulmonary nodules in both lung fields, which was detected incidentally on routine chest x-ray and followed by additional exmaminations including chest CT scan and percutaneous needle aspiration biopsy under the presumptive diagnosis of metastatic cancer. During thoracoscopy, the result of the frozen section analysis of multiple masses revealed strong evidence of leiomyoma. In her past medical history, she had undergone myomectomy, and hysterectomy, 7 year ago and 10 year ago, respectively. Based on permanent, special staining of specimen, estrogen receptor assay and review of past specimen of uterine myoma the final diagnosis was benign metastasizing leiomyomata from uterine myoma, the report was very uncommon in Korean and English literatures. The patient has been followed up for 2 year without special therapy, such as hormonal therapy.

Primary malignant lymphoma of lung is a very rare disease, only 0.34% of all malignant lymphomas. In our case, a 76 year old male patient had a solitary mass without lympha- denopathy at chest CT scan. He underwent right middle lobectomy through a posterolateral thoracotomy incision. Pathologic study confirmed a diagnosis of malignant lymphoma and chemotherapy was started by an oncologist.

Unresolved major pulmonary embolism (UMPE) is an uncommon condition which causes pulmonary hypertension, cor pulmonale and death. An accurate and prompt diagnosis of UMPE is very important in the management of such patients with pulmonary embolectomy. Follow-up lung scans can lead to earlier diagnosis of UMPE especially on patients who have a history of acute pulmonary embolism in the past and. present with pulmonary hypertension, respiratory insufficiency and cor pulmonale. We report a case of UMPE strongly suggested by follow-up lung scans and subsequently confirmed by pulmonary angiography and postmortem examination.

Primary malignant lymphomas of the lung are rare neoplasms representing 3.6% of all extranodal lymphomas and less than 1% of pulmonary malignancies, with its distinct clinicopathological features. A 60-year-old symptomatic man, who was a former non-smoker, had a cough and sputum. Chest roentgenogram and computed tomographic scan showed the presence of a posterior mass in the basal segment of the right lung. Transthoracic needle aspiration cytology was inadequate for the diagnosis of cancer. A subsequent right thoracotomy was carried out, which showed a primary pulmonary lymphoma of the bronchus-associated lymphoid tissue.
