[Ectopic Hilar Thymoma Associated with Morvan Syndrome after Extended Thymectomy for Myasthenia Gravis].

Morvan syndrome is a rare autoimmune neurological disease characterized by peripheral nerve hyperexcitability, autonomic dysfunction and encephalopathy. Morvan syndrome is often associated with thymoma as a paraneoplastic condition. Here we present a rare case of Morvan syndrome with ectopic hilar thymoma after extended thymectomy for myasthenia gravis.

[Metastatic Atypical Meningioma of the Lung;Report of a Case].

A 56-years-old woman, who had undergone a complete resection for atypical meningioma (grade 2 of World Health Organization classification)8 years before was admitted to our hospital to treat a mass on the right middle lobe detected by chest X-ray. The mass was resected successfully by video-assisted thoracoscopic surgery and pathological diagnosis of the tumor was a metastatic atypical meningioma. We experienced a rare case of extracranial pulmonary metastasis of meningioma.

[Pulmonary Metastasis of Sacral Chordoma Fifteen Years after Resection of Primary Site;Report of a Case].

A 71-years-old man, who had undergone resection for sacral chordoma 15 years before, was admitted to our hospital to treat a nodule in the right middle lobe detected by computed tomography. The nodule was resected and was histologically diagnosed as lung-metastasis of chordoma.

[Gastrointestinal Stromal Tumor with Metastasis of Chest Wall and Both Lungs].

A 60-years-old male, who had undergone surgery for gastrointestinal stromal tumor of small intestine 8 years before, was admitted to our hospital for surgical treatment of left 10th rib metastasis. Three months after the 1st operation new metastatic lesions appeared at hypodermic tissue at right anterior chest wall and left upper lobe of the lung and we performed 2nd operation to resect these lesions. Five months after 2nd operation, we performed 3rd operation to resect another metastatic pulmonary lesion at right upper lobe.

[Metastatic Ovarian Granulosa Cell Tumor of the Diaphragm Resected by Video-assisted Thoracoscopic Surgery;Report of a Case].

A 75-years-old woman, who had undergone a total abdominal hysterectomy and bilateral salpingo-oophorectomy for ovarian granulosa cell tumor( OGCT) 6 years ago, was admitted to our hospital to treat a mass on the right diaphragm detected by computed tomography. The mass was resected successfully by video-assisted thoracoscopic surgery and pathological diagnosis of the tumor was a metastatic OGCT of the diaphragm. To our knowledge, this is the 3rd case report of metastatic OGCT of the diaphragm.

[Open Drainage for Mediastinitis after Endobronchial Ultrasonography-guided Transbronchial Needle Aspiration].

A 61-year-old man had been diagnosed as lung cancer (cT4N2M0, stage IIIB) and radiochemotherapy was performed. After the treatment, endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA) was done to identify the histrogical type and to detect the oncogenic driver mutation. After EBUS-TBNA, he developed a high grade fever and the findings of the chest computed tomography (CT) suggested the infection of puncture site in mediastinum.

[Solitary Mediastinal Lymph Node Metastasis From Hepatocellular Carcinoma].

A 40-years-old Japanese female suffering from misswallowing and hoarseness, who had undergone hepatectomy due to hepatocellular carcinoma(HCC) 4 years before, revealed solitary subaortic mass in the chest computed tomography scan and fluorodeoxyglucose-positron emission tomography. The mass was surgically resected by video assisted thoracoscopic surgery and pathological examination revealed lymph node metastasis of HCC. Symptoms of recurrent nerve palsy disappeared after surgery.

[Rib Metastasis from Intracranial Hemangiopericytoma: Report of a Case].

A 65-year-old man had undergone the surgical treatment for intracranial hemangiopericytoma(HPC) in 2011. In June 2013, the X-ray abnormality in health examination was pointed out. Chest Computed tomography shows a 30 mm-sized tumor lesion with bone destruction in the 6th left rib bone.

[Subpectoral lipoma developing to cervix; report of a case].

A 54-year-old Japanese female, who presented slight swelling of the supraclavicular region due to soft indolent mass without neurological impairment, was admitted to our hospital to receive surgical treatment. Computed tomography (CT) and magnetic resonance imaging (MRI) revealed subpectoral mass surrounded by the minor pectoral muscle, the subscaplar muscle, and the bony thorax, and spread to cervix passing through between the right clavicle and the bony thorax, indicating similarity of the intensity and the density to subcutaneous fatty tissue, and then the mass was guessed to be extremely rare subpectoral lipoma. The lipoma was dissected successfully from adjacent subclavian artery and vein, brachial nerve, and surrounding muscles through sub-and supra-clavicular small skin incision without cut of the clavicle.

Phase II study of carboplatin and weekly paclitaxel combination chemotherapy in advanced non-small cell lung cancer: a Kansai Clinical Oncology Group study.

The objective of this phase II study was to evaluate the efficacy and toxicity of carboplatin and weekly paclitaxel combination chemotherapy in previously untreated, advanced non-small cell lung cancer (NSCLC). Patients received paclitaxel at a dose of 70 mg/m(2) on days 1, 8, 15, and carboplatin with the target dose of area under the curve (AUC) of 6 on day 1 every 28 days. Forty-six patients were enrolled.

Malignant peripheral nerve sheath tumor of small round cell type with pleomorphic spindle cell sarcomatous areas.

An unusual case of malignant peripheral nerve sheath tumor (MPNST) arising in the posterior mediastinum of a 59-year-old man is reported. Histopathologically, the tumor showed an admixture of a dense proliferation of small round cells resembling a primitive neuroectodermal tumor (PNET) and a pleomorphic spindle cell sarcomatous area. Abortive rosettes, primitive neural tube-like structures, and a few glandular structures were found in the small round cell area.

Pulmonary metastasectomy for 165 patients with colorectal carcinoma: A prognostic assessment.

Objective: The purpose of this study was to analyze our entire experience with pulmonary resection for metastatic colorectal carcinoma to determine prognostic factors and critically evaluate the potential role of extended metastasectomy.

Methods: We analyzed the postoperative survival of 165 patients who underwent curative pulmonary surgery at eight institutions in the Kansai region of western Japan (Kansai Clinical Oncology Group) from 1990 to 2000.

Results: Overall survivals at 5 and 10 years were 39.
