Lymphomatoid granulomatosis (LYG) is an angiocentric and angiodestructive neoplastic proliferation of B and T lymphocytes commonly involving the lungs. Epstein-Barr virus is commonly detected in lesional cells. We report a case of a 54-year-old female with underlying monoclonal gammopathy of unknown significance who presented with a 4 week history of dyspnea and cough. Computed tomography scan of the chest showed multiple lung nodules as well as endobronchial narrowing causing atelectasis at the left upper lobe. Bronchoscopic findings revealed obstruction at the lingula segment due to endobronchial mass as a rare presentation. Bronchoscopic biopsy was diagnosed with LYG grade 1. After treatment, the endobronchial mass and lung lesions were completely resolved. However, the patient eventually evolved to malignant lymphoma after 1 year.

Report of right atrial thrombus complicating pulmonary embolism after cardiac surgery is rare. A 54-year-old woman operated on the atrial septal defect 10 months ago was admitted for left pleuritic pain and dyspnea. Multiple segmental perfusion defects were detected in lung perfusion scan. Transesophageal echocardiography showed a large mobile right atrial mass attached to the free wall of the right atrium with a stalk. Despite the intravenous heparinization for 13 days, follow-up echocardiography revealed the right atrial mass had not diminished in size. The mass which was confirmed as an organizing thrombus was excised under cardiopulmonary bypass. The patient recovered uneventfully and was discharged on warfarin therapy.

Pulmonary artery sarcoma (PAS) is a rare and fatal disease that often mimics chronic thromboembolic pulmonary hypertension (CTEPH); therefore, diagnosis of PAS is often delayed. Herein, a healthy 74-year-old man was presented with a 4-month history of dyspnea. Chest computed tomography showed wall thickening and stenosis in the main pulmonary artery as well as in both proximal pulmonary arteries. In order to differentiate between unusual CTEPH, vasculitis, and PAS, we performed right heart catheterization and pulmonary angiography. The mean pulmonary arterial pressure was 21 mmHg, and there was severe pulmonary artery stenosis. Thrombi on the pulmonary arterial wall lesions were observed in intravascular ultrasound and optical coherence tomography. Furthermore, the patient had a history of deep vein thrombosis. Therefore, we diagnosed unusual CTEPH. After 6 months of rivaroxaban anticoagulation therapy, a chest X-ray revealed a left lower lobe lung mass, and a positron emission tomography later showed hypermetabolic lesions in the main pulmonary artery wall, in both pulmonary arteries walls, in the lung parenchyma, and in the bones. A biopsy of the right proximal humerus lesion revealed undifferentiated intimal sarcoma. Pulmonary sarcoma is rare, but should be considered when differentially diagnosing main pulmonary artery wall thickening and stenosis. A positron emission tomography may aid in this diagnosis.

Pulmonary function test has been know to be greatly affected by body indices, such as sex, age, height, body weight, body surface area (BSA) and body mass index (BMI), so hat this study was focused to see the relationship between body index and flow-volume curves. Subjects were 156 (male 90, female 66) and they were examined for pulmonary function test in terms of body index and correlation/multiple regression analysis of flow-volume curves at Presbyterian Medical Center from March to August, 2009. The followings results after analyzing the correlation between body index and flow-volume curves. Although flow-volume curve FEF25-75% showed close correlation with age, body weight, and body surface area, but not with body mass index. In addition, multiple regression analysis was performed to see how each body index affects flow-volume curve FEF25-75%, and FEF25-75% dispersion was explained as 74.5% with age only, 94.2% with age and height, and 96% with age, height, and sex. Therefore, sex, age and height that are mainly used for predictive formular of pulmonary function test and nomogram were important factors for pulmonary function test itself, and further study must be done for other body index.

We report here on an uncommon case of metastatic choriocarcinoma to the lung, brain and lumbar spine. A 33-year-old woman was admitted to the pulmonary department with headache, dyspnea and hemoptysis. There was a history of cesarean section due to intrauterine fetal death at 37-weeks gestation and this occurred 2 weeks before admission to the pulmonary department. The radiological studies revealed a nodular lung mass with hypervascularity in the left upper lobe and also a brain parenchymal lesion in the parietal lobe with marginal bleeding and surrounding edema. She underwent embolization for the lung lesion, which was suspected to be an arteriovenous malformation according to the pulmonary arteriogram. Approximately 10 days after discharge from the pulmonary department, she was readmitted due to back pain and progressive paraparesis. The neuroradiological studies revealed a hypervascular tumor occupying the entire L3 vertebral body and pedicle, and the tumor extended to the epidural area. She underwent embolization of the hypervascular lesion of the lumbar spine, and after which injection of polymethylmethacrylate in the L3 vertebral body, total laminectomy of L3, subtotal removal of the epidural mass and screw fixation of L2 and L4 were performed. The result of biopsy was a choriocarcinoma.

Pulmonary blastoma is a very rare, primary, malignant neoplasm of the lung. The tumor typically is large, well-defined mass and arises in the periphery of the lung. Histologically, it resembles fetal lung tissue evoking the concept that these tumors are drived from the primitive pluripotential pulmonary blastema, but controversy also exit about the nature of this tumor. Clinical evaluation is inconsistant and unreliable as to the diagnostic determination of the tumor type and degree of malignancy. Therefore, diagnosis is usually based on histologic findings. The prognosis after adequate resection appears to be better than for other malignant tumors of the lungs. We experienced a case of pulmonary blastoma occurring in 56-year-old female. She was hospitalized for evaluation of an abnormal shadow in the left lower lung field which found incidentally on chest roentgenogram. We approached the lesion though left posterolateral thoracotomy and performed the left lower lobectomy. The microscopic findings of resected specimen revealed characteristic appearance of pulmonary blastoma. The postoperative course was uneventful without complication.

Pulmonary hamartoma is an uncommon benign tumor consisting of a mixture of loose fibromyxoid tissue, cartilage, fat, and cleft-like spaces lined by cuboidal or ciliated epithelium. Cytologically, the presence of a mesenchymal component is essential for the diagnosis of pulmonary hamartoma. We report the fine needle aspiration cytologic findings of two cases of pulmonary hamartoma. Case 1 was a 71-year-old woman with a mass, measuring $1.8{\times}1.5cm$ in the upper lobe of the right lung. Case 2 was a 51-year-old woman with a mass, measuring $2.3{\times}2.0cm$ in the lower lobe of the right lung. Fine needle aspiration cytology of both pulmonary masses revealed several sheets of loose fibromyxoid tissue fragments with focal cartilaginous differentiation and a few clusters of bland cuboidal epithelial cells on the bloody background. The diagnosis was histologically confirmed by needle biopsy.

Purpose: The purpose of this study was to examine the impact of body mass index (BMI) and waist circumference (WC) for pulmonary function in normal-weight and obese women. Methods: Data from women aged ${\geq}40$ years were obtained from the 2011 Korean National Health and Nutrition Examination Survey. Obesity was measured by BMI and WC and pulmonary function was measured by forced vital capacity (FVC), forced expiratory volume in 1 second ($FEV_1$), and a ratio between forced expiratory volume in 1 second ($FEV_1$/FVC). Multiple linear regression analysis was performed for assessment of the association between FVC, $FEV_1$, $FEV_1$/FVC and obesity variables. Results: BMI showed positive association with FVC, $FEV_1$, $FEV_1$/FVC, and WC showed positive association with $FEV_1$ and $FEV_1$/FVC in normal-weight women. BMI and WC showed negative association with FVC, $FEV_1$ in obese women. A 1 unit increase in BMI showed an association with a 25-mL reduction in FVC and a 19-mL reduction in $FEV_1$. A 1-cm increase in WC showed an association with a 6-mL reduction in FVC and a 4-mL reduction in $FEV_1$. Conclusions: BMI and WC showed negative association with pulmonary function in obese adult women. Therefore, obese women with reduced pulmonary function should be encouraged to lose weight for improvement of their pulmonary function.

The primary pulmonary lymphomas are uncommon, accounting for 0.5% of primary lung tumor and 0.4% of all malignant lymphomas. The majority of primary pulmonary lymphomas are of B-cell originating from bronchus associated lymphoid tissue(BALT). Angiocentric lymphoma is a rare type of primary pulmonary lymphomas characterized by polymorphic lymphoid infiltrates, which make it even more difficult to differentiate from benign infiltration. The radiographic findings are variable, depending on the stage of evolution of the disease. The prognosis of angiocentric lymphoma is poor, nearly two-thirds of the patients with grade 2 or 3 angiocentric lymphomas were died within a year of diagnosis. We report a case of primary pulmonary angiocentric lymphoma manifested as a mass of right lower lobe.

The majority of lung cancers associated with hyperamylasemia are adenocarcinomas. Here we report an unusual case of a 54-year-old male patient who complained of dyspnea, anterior chest wall discomfort and facial edema for one month, presenting with a huge mediastinal mass and hyperamylasemia complicated by pericardial effusion. Histological evaluation of mediastinal mass revealed small cell carcinoma and pericardium showed nonspecific inflammation with fibrosis. The serum amylase had an electrophoretic mobility similar to that of salivary gland enzyme. There were no evidence of a salivary or pancreatic causes of hyperamylasemia. After chemotherapy, parenchymal lung lesions improved and hyperamylasemia disappeared. For the management of pericardial effusion, a pericardial window was formed. We concluded that the striking increase in serum amylase was due to the ectopic production of this enzyme by the tumor.
