We report the case of a woman in her 50s, who presented with an abnormal shadow on a chest radiograph. Computed tomography revealed a left pleural cavity tumor (15 cm in maximum diameter), which ...showed a mixture of cystic and solid components. We performed a thoracotomy for complete en bloc tumor removal, together with a thymectomy. A postoperative histopathological examination confirmed the diagnosis of a type B3 thymoma, Masaoka stage I. At the time of writing this report, no tumor recurrence had been observed over a postoperative period of 24 months. This study describes a rare case of the successful surgical resection of a giant thymoma.
Apical pleurodesis procedures, in addition to the resection of bullae or blebs, proved to lower the recurrence rate in spontaneous pneumothoraces. Here, we describe our thoracoscopic technique of ...making a 360° apical pleurodesis. After resecting responsible bullae or blebs thoracoscopically, we dissect the parietal pleura off the chest wall up, turn it over on the mediastinal side, clip it on the mediastinal pleura and place the lung apex against the rough surface to promote extensive apical pleurodesis. The technique has been performed for 18 patients so far and no late recurrence of pneumothorax has been noted.
A 64-year-old woman underwent polypectomy for a rectal polyp(Isp). Pathological findings were invasion of the submucosa( 3,500 mm diameter), and she underwent anterior resection for rectal cancer(RS, ...pT1b, pN0, cM0, Stage I )without adjuvant chemotherapy. Lung masses were found in her right(8mm)and left lung(7mm). The tumors enlarged during the 4 month follow-up period. We decided to perform left partial pneumonectomy. The tumor was diagnosed as a lung metastasis from colon cancer by pathology. Because the right tumor was located towards the center, performing right pneumonectomy would have been quite invasive and we feared occult metastases. We decided to apply SRT(50 Gy)to the right tumor. The tumor shrunk and became a scar after treatment. There were no complications such as radiation pneumonitis. The patient was in good health without any recurrence for 12 months after SRT. Surgical resection is an optimal method to control lung metastasis from colon cancer if the lesion is operable. However, in the case of a tumor centrally located, surgical resection may cause deterioration of lung function. There are also cases with contraindications for surgery due to co-morbidities. In addition, there is no consensus on observation periods to exclude occult metastases. SRT can be an effective treatment for lung metastases from colon cancer when there are bilateral lung metastases and no metastases outside the lungs.
Background. We report a case of endobronchial metastasis from laryngeal cancer that was removed through snaring before resection of pulmonary metastasis. Case. A 64-year-old woman who had previously ...undergone a laryngectomy for laryngeal cancer was admitted to our institution because of dyspnea. Bronchoscopic examination revealed a tumor of 15mm in diameter in the trachea. Because of the possibility of airway occlusion, this tumor was resected by endobronchial electrosurgical snaring, without bleeding. Conclusion. Endoscopic resection with high-frequency electrosurgical snaring was safe and useful in this case.
We present a rare case of solitary pulmonary papilloma. A 74-year-old woman consulted our hospital because of blepharoptosis. Chest CT and MRI demonstrated a tumor in the thymus and a small mass ...lesion in the lower division of the right lung. We performed extended thymothymectomy and partial resection of the right lower lobe. On postoperative pathologic examination, the tumor in the thymus was diagnosed as thymoma of type B, and the nodule of the lung was mixed squamous cell and glandular papilloma. The postoperative course was excellent, without any complications. Peripheral pulmonary papilloma is rare, with only eight cases being reported in the literature. We have to consider treatment with or without surgery because it is difficult to diagnose the lesion as benign or malignant on preoperative examination. Furthermore, we should strictly observe the postoperative course because papilloma has the possibility of becoming malignant.
We report a case of triple cancer of the pancreas, colon, and peripheral nerve sheath. A 68-year-old woman diagnosed with type 2 diabetes at age 63 had been administered antidiabetic oral medications ...since then. Her HbA1c had been 6.0-7.0 % in NGSP. We found that, in the last 5 months, her HbA1c had increased by 3.5 % and she had lost 9 kg, suggesting the need to check for possibly malignant disease. Contrast-enhanced computed tomography showed 1 tumor each of the pancreas, chest wall. Preoperative colonoscopy showed a tumor of the colon. The first two tumors, diagnosed pathologically as cancer of the pancreas and of the peripheral nerve sheath, were completely resected with no significant metastasis. The third tumor, diagnosed as cancer of the colon, was removed by endoscopic mucosal resection. Symptoms in those with diabetes that include progressive weight loss and deteriorating glycemic control should thus suggest the need to check for possibly malignant disease.
We present a rare case of primary pulmonary collision tumor. A 72-year-old man was pointed out as having an abnormal shadow in the right lung. Chest CT revealed a heterogenous opacity (71×60×22 mm) ...and a nodule (22×20×12 mm) in the right lower lobe. Lung cancer was suspected, and right lower lobectomy was performed. This lesion was histopathologically diagnosed as a collision tumor of adenocarcinoma and squamous cell carcinoma. A clear border was present between the tumors. Both tumors were diagnosed as pT2N0M0, p-stage IB disease. The postoperative course was excellent, without any complications. The patient was followed-up with the oral administration of uracil and tegafur as postoperative adjuvant chemotherapy. Multiple pleural dissemination and pulmonary metastasis nodules appeared 10 months after the operation.
