Lung cancer remains a deadly disease with unsatisfactory overall survival. Resveratrol (Res) has the potential to inhibit growth of several types of cancer such as prostate and colorectal examples. In the current study, we evaluated in vitro and in vivo anticancer efficiency of Res in a xenograft model with A549 cells. Cell inhibition effects of Res were measured by MTT assay. Apoptotis of A549 cells was assessed with reference to caspase-3 activity and growth curves of tumor volume and bodyweight of the mice were measured every two days. In vitro cytotoxicity evaluation indicated Res to exert dose-dependent cell inhibition effects against A549 cells with activation of caspase-3. In vivo evaluation showed Res to effectively inhibit the growth of lung cancer in a dose-dependent manner in nude mice. Therefore, we believe that Res might be a promising phytomedicine for cancer therapy and further efforts are needed to explore this potential therapeutic strategy.

Empyema with bronchopleural fistula is an uncommon, but serious problem. Early diagnosis and adequate drainage of the empyema cavity are well established principles for the initial management of this condition and will enable patient to recover from the toxic effects of loculated pus. 37 patients of empyema with bronchopleural fistula were treated at the department of the chonbuk National University Hospital between 1981 and 1988. The age group of fifty and sixty decades occupied 64.8%. Bacteriologic cultures of the pus were postive in 56.8%. The most common organism of the culture was staphylococci(42.9%). And the others were Pseudomonas(19%). Klebsiella(14.3%), and E. doli. No growth of pathologic organism was reported 43.2%. 24 patients of empyema with bronchopleural fistula were nonoperative causes : There were 10 pulmonary tuberculosis, 3 abscess, 9 ascending infection, one bronchiectasis and one tumor, respectively. The remaining 13 were occurred as postoperative complications ; pneumonectomy in 6, lobectomy in 4, decortication in 2, and lobectomy with segmentectomy in 1. When used as the initial mode of drainage, closed thoracostomy was performed to almost all of the patients, but 4 patients were died during this treatment. Main operations were performed except 4 died patients ; open thoracostomy in 21, open thoracostomy with myoplasty in 3, decortication in 5, decortication with resection in 3, and completion pneumonectomy in 1. Open thoracostomy was performed in 21 patients which results were favorable except one death. Permanent open thoracostomy is an old but still useful minor operation in patients with empyema with bronchopleural fistula. The overall mortality rate was 15% (6 patients) and the causes of the death were respiratory insufficiency or sepsis, or both.

Since sclerosing hemangioma of the lung was first described by Liebow and Hubbell in 1956, there have been several reports on cases occurring as a solitary nodule; however, sclerosing hemangiomas occurring as multiple nodules are extremely rare. The histogenesis of this tumor remains controversial and there are several hypotheses of the etiology. Three separate nodules were found in a 57-year-old housewife, one found in the right middle lobe, one in the apicoposterior segment of the left upper lobe, and one in the superior segment of the left lower lobe. The only symptom or sign presented was a dry cough. Apicoposterior segmentectomy of the left upper lobe and wedge resection of the superior segment of the left lower lobe were performed. The postoperative course was uneventful and the patient was discharged on the postoperative 15th day.

The recurrence of an anterior mediastinal mass was discovered incidentally on the chest film for an asymptomatic 72-year-old female. She underwent the mass resection at the same site in 1989 and was diagnosed as a paraganglioma of the anterior mediastinum. She had poorly controlled hypertension which was converted into normal blood pressure after the first operation. During the follow up, the catecholamine levels were within normal limits, and there were no evidence of recurrence of the tumor. However, 6.3 years later, the mass recurred at the same anterior mediastinum. The patient had no hypertension and catecholamine levels were still within normal limits. The recurring mass was successfully removed and had the same histological findings - recurring paraganglioma.

Primary pulmonary arterial sarcomas, especially those originating from the pulmonary valve are extremely rare. A 35 year-old male patient was admitted for exertional dyspnea and fatigue. Large intraluminal mass in the main pulmonary artery and both pulmonary arteries was detected by chest computed tomogram, chest magnetic resonance imaging, echocardiogram, and pulmonary angiogram. We regarded the mass as a primary pulmonary arterial malignant tumor, and resected under cardiopulmonary bypass. The mass was appeared to originate from the posterior cusp of pulmonary valve, and extended from below pulmonary valve to main pulmonary artery and both pulmonary arteries. We resected the mass by pulmonary endarterectomy and replaced the pulmonary valve. The mass was diagnosed as a pulmonary arterial sarcoma in histopathologic examination.

Chylothorax or chylous ascites are rare manifestations of liver cirrhosis. We report a rare case of simultaneous chylothorax and chylous ascites in a patient with hepatitis B virus-related liver cirrhosis. A 76-year-old woman was referred to our hospital with a pleural effusion on her right side. She had no history of recent medical procedures, trauma or tumor. There was no evidence of mass or thoracic duct obstruction in a computed tomography scan. Pleural fluid and ascites were confirmed as chylothorax and chylous ascites by chemistry analysis. Despite thorough conservative care, there was no improvement. Pleurodesis was planned, but hepatic encephalopathy developed suddenly and she did not recover.

We report a case of a 13-year-old girl with acute lymphoblastic lymphoma- leukemia, who presented with a cardiac metastasis in the right ventricle, resulting in a pulmonary embolism. At the time of her leukemia diagnosis, a cardiac mass was incidentally found. The differential diagnosis for this unusual cardiac mass included cardiac tumor, metastasis, vegetation, and thrombus. Empirical treatment was initiated, including anticoagulation and antibiotics. She underwent plasmapheresis and was administered oral prednisolone for her leukemia. Five days later, she experienced sudden hemodynamic collapse and required extracorporeal membrane oxygenation insertion and emergency surgery. These interventions proved futile, and the patient died. Pathology revealed that the cardiac mass comprised an aggregation of small, round, necrotic cells consistent with leukemia. This is the first known case of acute lymphoblastic leukemia presenting as a right ventricular mass, with consequent fatal acute pulmonary embolism. A cardiac mass in a child with acute leukemia merits investigation to rule out every possible etiology, including vegetation, thrombus, and even a mass of leukemic cells, which could result in the fatal complication of pulmonary embolism.

A 1.5-year-old male Golden Retriever was presented with worsening lameness of two month duration. Abnomral findings of blood works and serum chemistry included anemia, thrombocytopenia, hypercalcemia and hyperglobulinemia. Radiography revealed osteolysis of polyostotic regions including right femur and tibia, bilateral ilium, and spinous processes from the 13th thoracic vertebra to 5th lumbar vertebra. Enlarged multiple lymph nodes and mixed echo pattern of muscular region ventral to vertebra were observed with ultrasonography. Because concentrations of both parathyroid hormone and parathyroid hormone related peptide were all within reference ranges, humoral hypercalcemia by tumor was ruled out and extensive osteolysis was considered as the cause of hypercalcemia. Based on radiographic and ultrasonographic study, lymphoma, multiple myeloma and osteomyelitis were included in differential diagnosis. Fungal serologic test was negative. Monoclonal gammopathy was not found on serum protein electrophoresis. Cytological and histopathological examinations of the lytic lesions revealed neoplastic lymphoid proliferation, and B cell type clonal expansion was detected by polymerase chain reaction for the antigen receptor gene rearrangement. The case was diagnosed as B cell lymphoma involving polyostotic regions.

Endobronchial lipomas are rare benign tumors that arise from the lung. They partially or totally obstruct the bronchial lumen, producing a variable degree of collapse, irreversible bronchiectasis, and pulmonary damage. Although bronchoscope, CT and MR are reported to be helpful in establishing the diagnosis, CT is highly specific and sensitive in detecting fatty tumor. They may be removed by endoscope or thoracotomy or lobectomy. We present a case of endobronchial lipoma completely obstructing the right middle lobe and postobstructive irreversible pulmonary change with review of literatures.

Epithelioid hemangioendothelioma, originating from the vascular endothelium, is a very rare and low-grade malignancy. World-wide, about 50 cases of pulmonary epithelioid hemangioendothelioma have been reported. This is more common in female and is usually shown as multiple nodules in both lung fields. A 41-year-old male, who had suffered from right pleuritic chest pain for 3 months, was initially diagnosed as adenocarcinoma under bronchofiberscopic biopsy. At that time, the stage of tumor according to the TNM staging was llla. He received bronchoscopic biopsy again during follow-up period and it was diagnosed as hamartoma. After surgery, the final diagnosis was pulmonary epithelioid hemangioendothelioma.
