Immature teratoma can be viewed as intermediate between mature teratoma and embryonal carcinoma. Unlike the mature teratoma, elements of the three perm cell layers are incompletely differentiated and not arranged in organoid fashion In some area, more mature forms of these tissues may also be seen, Although this tumor is clearly malignant, they may not display clear-cut cytologic features of malignancy. The clinical prognosis is poor. We have experienced one case of recurrent immature teratoma. In first operation[1987, April], tumor of anterior mediastinum was removed with wedge resection of ant. segment of RUL % med. segment of RML. In 2nd operation[1990, June], recurrent teratoma of right inner thoracic wall was resected with partial 5th rib resection and wedge resection of lat. segment of middle lobe. Two months later, the 3rd operation[1990, September] was done, which was a removal of mass on thoracic wall near sup, segment of RLL and partial rib resection of 3rd, 4th & 5th. In November 1990, last operation[4th operation] was made. It was enucleation of walnut sized tumor located between medial segment of RML, and 4th. intercostal space, well encapsulated with endothoracic fascia and invaded into lung parenchyme, Adjuvant chemotherapy was done after each operation, but radiotherapy[5000 Rad] was done only after 1st operation. There was no evidence of recurrence after last operation. The patient is well-being still now.

This report describes the case of a 57-year-old man with an anterior mediastinal tumor. Four years previously, he underwent laparoscopic anterior resection for sigmoid colon cancer. Thirty months after that procedure, bilateral pulmonary metastasectomy was performed. Twelve months later, follow-up computed tomography revealed a 1-cm pulmonary nodule on the upper lobe of the right lung and a solid mass on the anterior mediastinum, and the patient was also observed to have an elevated serum carcinoembryonic antigen (CEA) level. Repeated pulmonary nodule resection and total thymectomy were performed. Immunohistochemical staining of the anterior mediastinal tumor revealed adenocarcinoma, and his serum CEA level returned to normal after the operation. These findings strongly suggested metastatic thymic adenocarcinoma from a colorectal cancer.

A 3-year-old boy with purulent otitis media received a chest radiograph as the part of a routine work up. The patient was normal appearing, in no acute distress. The patient's lung and heart sounds were clear and normal. The patient's abdomen was soft, non-distended, and non-tender. An anterior cardiophrenic mass was incidentally identified on the lateral chest radiograph. A computed tomography scan demonstrated a diaphragmatic hernia with bowel loops in the retrosternal space. An exploratory operation revealed a diaphragmatic defect (4 cm in diameter) on the left side of the falciform ligament, through which transverse colon was protruded. There was no hernia sac, and the defect was closed with interrupted No. 2 silk sutures. The child was discharged on the 8th postoperative day without any complications. During 6 months of follow-up period, recurrence was not noticed.

After the new house symptoms recently, room environment pollution problem of building syndrome and so on is becoming research about ways to solve this being risen. Is taking advantage of nature data by building materials by one of this way, but Friendly Environmental performance examination for structure material is insufficient misgovernment being real condition that put emphasis in ability as most embellishment and in finish. Environmental examination is insufficient misgovernment on factor itself as structure material. Also, being real condition that radon that is responsible for lung cancer occurrence next to smoke in building materials such as concrete and so on is happened, the danger is reported much through mass communications and research paper etc. Therefore, this research measured radon release amount and the carbon dioxide adsorption rate for physical special quality measuring and Friendly Environment Efficiency that follow to 'KS F 4004 Concrete bricks' regulation after manufacture Concrete Bricks utilizing charcoal that is nature material by sand. This study finding carbon dioxide density appeared and displayed effect that charcoal Controls radon release that happen in Concrete Bricks to maximum 74% that decrease to best 95% though decreased the charcoal addition rate increases.

Pulmonary aspergillosis may present with three different features, according to the immune status of the host. These forms are invasive aspergillosis, allergic bronchopulmonary aspergillosis (ABPA) or aspergilloma. Bronchial involvement is an uncommon type of invasive pulmonary aspergillosis. We encountered an unusual case of an endobronchial aspergillosis that completely obstructed the left upper lobe, which was initially thought to be lung cancer. We report this case along with a review of the relevant literature.

Thymomas are one of the most common neoplasms of the mediastinum derived from thymic epithelium. It is common that invasive thymoma invades the lung, pericardium, and great vessels. Airway compression by mass effect also occurs, but direct polypoid tumor growth into the airway is extremely rare. Only 20 cases of invasive thymoma with endobronchial polypoid growth have previously been reported globally. However, there is no case report of invasive thymoma with endotracheal growth. Herein, we report a rare case of invasive thymoma with endotracheal polypoid growth in a 28-year-old woman.

Diaphragmatic paralysis can be demonstrated through diaphragmatic elevation on chest X-ray after thoracic lung surgery or the placement of chest tubing. Additional causes of diaphragmatic paralysis are iatrogenic, mass, atelectasis, etc. For the diagnosis of diaphragmatic paralysis, it required some studies (fluoroscopy, computed tomography [CT], magnetic resonance imaging). Diaphragmatic hernia of the liver is a rare clinical entity, usually found after trauma in adults. Congenital diaphragmatic hernia in neonates requires surgery. Non-traumatic diaphragmatic hernia of the liver in an adult is a rare right-sided diaphragmatic hernia. On developing any symptoms, surgery must be performed. When diaphragmatic hernia is incidentally found in adults without trauma, it is placed under observation for a time period. We diagnosed the diaphragmatic herniation of a right hepatic lobe by 16-slice CT scan without surgery.

Chronic obstructive pulmonary disease(COPD) is characterized by a not entirely reversible limitation in the airflow. An airflow limitation is progressive and associated with an abnormal inflammatory response of the lung to gases and harmful particles. In COPD, the weight loss is commonly observed and there is a negative impact on the respiratory as well as skeletal muscle function. The pathophysiological mechanisms that result in weight loss in COPD are not fully understood. However, the mechanisms of weight loss in COPD may be the result of an increased energy expenditure unbalanced by an adequate dietary intake. The commonly occurring weight loss and muscle wasting in COPD patients adversely affect the respiratory and peripheral muscle function, the exercise capacity, the health status, and even the survival rates. Therefore, it is very valuable to include management strategies that the increase energy balance in order to increase the weight and fat free mass. A Better understanding of the molecular and cellular pathological mechanisms of COPD can improve the many new directions for both the basic and clinical investigations. The Nutritional supply is an important components of a multidisciplinary pulmonary rehabilitation program. Future studies combining an exercise program, the role of anabolic steroids, nutritional individualization, a more targeted nutritional therapy, and the development of new drugs including anti-cytokines is needed for the effective management of COPD.

Objective: To assess differences in serum proteins in esophageal squamous cell carcinoma patients. Methods: 144 esophageal squamous cell carcinoma patients and 50 healthy volunteers were included in this study, with surface-enhanced laser desorption-ionization time-of-flight mass spectrometry and weak cation exchange magnetic beads. Follow-up allowed the relations between serum proteins and prognosis to be analyzed. Results: A total of 93 protein peaks were detected (molecular weight range: 1500-30000), 10 demonstrating statistically significant differences. There were no differences in protein peaks between 92 patients with a survival more than 2 years and 52 patients with survival less than 2 years. There were two significantly different protein peaks between 45 stage II patients with a survival more than 2 years and 14 stage II patients with survival less than 2 years. There was one significantly different protein peak between 22 stage III patients with a survival more than 2 years and 29 stage III patients with survival less than 2 years. Conclusion: Differences of serum proteins in esophageal squamous cell carcinoma are related to prognosis of patients. The protein fingerprint can be helpful for clinical diagnosis and treatment.

A 16 year-old female grey pony was presented to Animal and Plant Quarantine agency for diagnosis in Feb 2, 2015. At necropsy, multiple pigmented masses, likely melanomas, were detected peri-anally and under the tail. Further metastatic spread to the spleen, liver, lung and lymph nodes was also identified. Histopathologically, anaplastic and pleomorphic melanocytes were observed in the mass. By immunohistochemistry, PNL2, S100 and PGP 9.5 protein were detected, but Melan A was not expressed in the neoplastic melanocytes. Based on the pathological and immunohistochemical examination, we diagnosed this case as malignant melanoma in a grey pony. To the authors' knowledge, this is the first report of equine malignant melanoma in republic of Korea.
