OBJECTIVES The pleural invasion (PL) score is a useful prognostic indicator in lung cancer. However, in many cases, the cancer may exfoliate itself into the pleural cavity and may progress to a malignant pleural effusion without invading the parietal pleura. This stage is not currently evaluated, but it is detectable by means of the pleural lavage cytology(More)
Sternal tumors are uncommon, which often require extended resections with reconstructions. Various techniques have been used, including a choice of prostheses and the use of musculocutaneous flaps for reconstructions. A 74-year-old male presented with a metastatic sternal tumor. He underwent a subtotal sternectomy with partial resection of bilateral(More)
OBJECTIVE Despite recent advances in video-assisted thoracoscopic lobectomy, some technical limitations still remain. Our current study purpose was to determine if the vessel sealing system (VSS) has utility in this procedure. METHOD 112 patients who underwent an anatomic pulmonary lobectomy at our institute were evaluated retrospectively. The burst(More)
Birt-Hogg-Dubé syndrome (BHD) is an autosomal dominant disease caused by mutations of germline folliculin (FCLN) mapped in the chromosome 17p11.2 region. BHD commonly accompanies renal tumors, fibrofolliculomas, multiple pulmonary cysts, and spontaneous pneumothorax. We report a case of a young Japanese woman in whom asymptomatic bilateral pneumothorax was(More)
The measurements of exhaled nitric oxide (ENO) concentrations in several previous reports have been quite disparate but the cause of this variability is unclear. In the present study, we have attempted to elucidate the effects of expiratory pressure upon ENO values by taking measurements at pressures ranging from 2 to 10 cmH2O in control subjects and in(More)
BACKGROUND It is shown that low-dose computed tomography (CT) screening is useful for a reduction in lung-cancer-specific mortality in heavy smokers. However, the information about effectiveness according to the histological types of lung cancer has not been adequately investigated especially small cell lung cancer (SCLC). The present study was performed to(More)
BACKGROUND Lung cancer rarely metastasizes to the breast, and breast metastasis of pulmonary pleomorphic carcinoma has not been previously reported. CASE PRESENTATION The patient was a 66-year-old woman who became aware of a mass in the right breast and visited a physician. She was referred to our department for close examination, upon which she was(More)
