Successful Resection of a Giant Pulmonary Colloid Adenocarcinoma via Median Sternotomy.

We report on a giant pulmonary colloid adenocarcinoma successfully resected using a median sternotomy approach. A 69-year-old woman visited our hospital owing to a giant mass detected on chest radiography. A giant cystic mass measuring 115 × 90 mm was detected in the right upper lung using computed tomography.

Extralobar sequestration with a pulmonary arterial feeding vessel.

Extralobar sequestrations are rare congenital malformations of the lung. They are usually located between the diaphragm and left lower lobe and receive their blood supply from the aorta. We report a case of extralobar sequestration in an atypical location with a pulmonary arterial feeding vessel.

Metachronous Thin-Walled Cavity Lung Cancers Exhibiting Variable Histopathology.

We report a case of metachronous thin-walled cavity lung cancers exhibiting variable histopathology. A 70-year-old man visited our hospital because of a thin-walled cavity located in the right upper lobe, detected by chest computed tomography. Right upper lobectomy was performed and a histological diagnosis of squamous cell carcinoma was made.

Empyema and pyogenic spondylitis caused by direct Streptococcus gordonii infection after a compression fracture: a case report.

Background: Empyema and pyogenic spondylitis are common diseases that are often caused by oral pathogens in direct or hematogenous infection. However, there exists no report describing empyema and pyogenic spondylitis caused by oral pathogens after a compression fracture of the vertebral body. Herein, we report a case of empyema and pyogenic spondylitis caused by direct Streptococcus gordonii infection after a compression fracture of the vertebral body.

A solitary fibrous tumor arising from the thymus.

Solitary fibrous tumors (SFTs) are localized mesenchymal lesions which most frequently arise in the pleura but have also been observed in many other sites. SFTs arising from the thymus are relatively rare, however, and only a few cases have been reported to date. We report such a case in our current study.

Hepatocyte growth factor prevents pulmonary ischemia-reperfusion injury in mice.

Background: Ischemia-reperfusion (IR) injury after lung transplantation leads to significant morbidity and mortality in recipients, which remains the major obstacle in clinical lung transplantation. To reduce pulmonary graft dysfunction and improve prognosis after lung transplantation, prevention of IR-induced lung injury in the peri-operative period is required. In the present study, we investigated the effects of recombinant hepatocyte growth factor (HGF) on pulmonary IR injury using a murine model system.

Suppression of acute and chronic rejection by hepatocyte growth factor in a murine model of cardiac transplantation: induction of tolerance and prevention of cardiac allograft vasculopathy.

Background: Although treatment with immunosuppressive agents has contributed to overcoming acute rejection and improving the midterm survival of transplanted hearts, cardiac allograft vasculopathy (CAV) has remained the main cause of primary graft failure. Recent approaches have shown that hepatocyte growth factor (HGF) exhibits cardiotrophic functions. We therefore addressed whether HGF would regulate acute and chronic rejection in cardiac transplantation.

Chest wall myxoma protruding into the thoracic cavity.

Myxoma protruding from the chest wall into the thoracic cavity is very rare. We report our experience in treating a 42-year-old man admitted for a painless mass on the anterior chest wall. Magnetic resonance imaging showed a sharply defined 5 x 4 x 4 cm mass protruding from the chest wall into the thoracic cavity, which we excised surgically.
