A 58-year-old woman visited our hospital with the chief complaint of an abnormal chest shadow. Chest CT showed an 18-mm ground-glass opacity in the right upper lobe, which became enlarged over time, and lung cancer was suspected. At the same time, a tracheal bronchus originating directly from the trachea was observed. She underwent thoracoscopic right upper(More)
BACKGROUND Video-assisted thoracoscopic surgery (VATS) for clinical stage I non-small cell lung cancer (NSCLC) has been widely used as a less invasive surgical procedure, but the resection method is still controversial. We retrospectively compared the surgical outcomes of lobectomy, segmentectomy and wedge resection. PATIENTS AND METHODS A total of 411(More)
A 60-year-old female underwent right upper lobectomy of the lung and lymph node dissection under a diagnosis of cancer in the upper lobe of the right lung. Pathological examination showed stage IIIA adenocarcinoma with mediastinal lymph node metastasis. One month after the operation, adjuvant chemotherapy with carboplatin (CBDCA) and paclitaxel (PTX) was(More)
BACKGROUND/AIM Podoplanin is a candidate cancer stem cell marker in squamous cell carcinoma (SCC). Several studies have reported the prognostic value of podoplanin expression in tumor cells in lung SCC but few have focused on its expression in cancer-associated fibroblasts (CAFs). The aim of this study was to analyze the prognostic significance of(More)
A 66-year-old man was diagnosed as lung cancer. We performed right upper lobectomy and lymphnode dissection. On the 1st postoperative day, a chest radiograph showed an opacification in the right upper lung field. Computed tomography (CT) showed a stenosis of the middle lobe bronchus and infiltrative shadow of the middle lobe on the 3rd postoperative day.(More)
We report 3 cases of patients with bronchogenic cyst arising in the posterior mediastinum. The patients were a 19-year-old male, a 36-year-old female and a 33-year-old female, whose cysts were detected as abnormal shadows in the chest. In 2 of them, neurogenic tumors were suspected preoperatively. We performed thoracoscopic resection for the 3 tumors.(More)
We report a 58-year-old man who suffered from shortness of breath on exertion with wheezing. A chest enhanced computed tomography (CT) scan showed an irregular tumor in the middle mediastinum involving the right main pulmonary artery, vena cava superior and right main bronchus. Transbronchial lung biopsy and endobronchial ultrasound-guided transbronchial(More)
Herein, we report a patient with a rare disease, intrapulmonary schwannoma. The patient was a 61-year-old woman who had a 20 mm × 18 mm nodule, with a clear boundary and homogeneous content, on the central side of S4 in the right lung on chest CT. On PET with 18- fluorodeoxyglucose scanning, 18-fluorodeoxyglucose accumulations with a maximal standardized(More)
We report a rare case of thymic metastasis of breast cancer. A 68-year-old woman, who had undergone surgery for cancer in her right breast and had been free of recurrence for 22 years, was noted to have an abnormal shadow on a chest X-ray at a regular medical checkup. Further workup, including chest CT, revealed a 22 × 18-mm mass in the anterior(More)
We performed robot (da Vinci)-assisted thoracoscopic extended thymectomy (rThx) for myasthenia gravis with thymoma. The patient was a 66-year-old woman who complained of palpebral heaviness. Robotic operation was performed in the supine position by placing four ports in the right chest wall under 10 mmHg CO(2) insufflation using three arms and one assist(More)
