Solitary plasmacytoma of the bone, and especially of a single rib, is a rare disease. Here we report a 73-year old male patient complaining of continuous chest wall pain around the right 5th rib shaft who underwent a wide excision of the rib tumor with surrounding connective tissue. He was diagnosed with solitary plasmacytoma and will undergo radiation therapy. We report this case with a review of the literature.

A 39-year-old man presented to the department of emergency medicine in Seoul National University Hospital complaining of chest pain, heart palpitation, and headache. Upon arrival, a computed tomography scan showed a 7.0 cm×6.2 cm lesion with the typical features of a paraganglioma. The patient was treated with an alpha-blocker and a beta-blocker prior to surgical intervention. We removed the tumor successfully, and histopathologic findings indicated that the tumor was indeed a paraganglioma. Since intracardiac paraganglioma is a rare disease, we present this case together with a literature review.

We report the case of a 69-year-old woman who was diagnosed with intracardiac schwannoma without symptoms. Preoperative echocardiography and cardiac magnetic resonance imaging showed a mass attached to the interatrial septum. The initial diagnosis was a myxoma or a bronchogenic cyst. The tumor was successfully excised under cardiopulmonary bypass. However, the pathology of the excised tumor was consistent with schwannoma. We suggest that cardiovascular surgeons consider schwannoma to be a possible differential diagnosis for a mass close to the interatrial septum.

Undifferentiated pleomorphic sarcoma (UPS) arising from the descending thoracic aorta is a rare type of tumor. To our knowledge, only a few cases have been reported in the literature. We present computed tomography (CT) and magnetic resonance imaging findings of a 43-year-old male patient with undifferentiated pleomorphic sarcoma of the descending thoracic aorta, which showed enhancement on only magnetic resonance imaging (MRI). MRI with contrast enhancement may be useful in differentiating an aortic tumor from atherosclerotic disease.

Background: Pancreatic cancer is a highly aggressive solid tumor. Patients with metastases from pancreatic cancer have poor survival rates. Here, we report the outcomes of 6 patients for whom resection of lung metastases was performed after a pancreatectomy to treat pancreatic cancer. Methods: We retrospectively reviewed the perioperative clinical data of patients with lung metastases resulting from primary pancreatic cancer who were treated with lung resection between 2008 and 2015. We report 6 cases where lung resection was performed to treat lung metastases after a pancreatectomy. Results: The number of lung metastases was 1 in 5 cases and 2 in 1 case. The surgical procedures performed to treat the lung metastases included 4 wedge resections and 2 lobectomies. The cell type of the primary tumor and metastases was tubular adenocarcinoma in 5 cases and intraductal papillary-mucinous carcinoma in 1 case. All 6 patients survived with a mean follow-up period of 65.6 months, although the disease recurred in 2 patients. Conclusion: Resection of lung metastases resulting from primary pancreatic cancer may lengthen survival, provided the patient can tolerate surgery.

Pleuropulmonary blastoma (PPB) is an unusual intrathoracic blastoma presenting in childhood and charac-terized by a biphasic neoplastic population of undifferentiated, small round blastemal cells and larger spindle-shaped sarcomatous cells with entrapped benign epithelial-lined structures. We experienced the cytologic features of PPB in imprint smear from the pleural-based huge mass of the middle lobe of the right lung in a 4-year-old boy. The smears showed high cellularity composed of small ovoid blastemal elements and scattered spindle mesenchymal tumor cells. Lobectomy and pathologic investigation confirmed the diagnosis. PPB seems to be a tumor in which accurate diagnosis may be achieved by cytoiogy if appro-priate clinical information were given. Timely and accurate diagnosis of PPB by cytology paves the way for attempting preoperative treatment in future cases.

tumors. We report a primary cardiac myxosarcoma in a 40-year-old female patient who was admitted to the hospital because of exertional dyspnea and palpitation. The patient underwent emergency operation immediately after the intracardiac (left atrium) tumor was discovered by an echocardiography. Palliative tumor removal was done and final Pathologic diagnosis was primary cardiac myxosarcoma. She was discharged without complications.

We report a case of meningeal hemangiopericytoma presenting as metastasis in the vertebral body and pedicle of the thoracic spine. Hemangiopericytoma is a rare vascular neoplasm. Although the tumor has a strong propensity for both local recurrence and extracranial metastasis, metastasis to thoracic spine is very rare and only two cases were found in the literature. A 44-year-old woman with paraparesis and pain in the thoracic and lower legs was examined by plain radiographs and magnetic resonance imaging. The intracranial hemangiopericytoma was operated 3 years ago. Magnetic resonance imaging demonstrated a tumor invading the left vertebral body and pedicle of the 11th thoracic spine, and compressing the dural sac. The patient was gradually improved after surgical removal of the lesions and the histologic findings were characteristics of hemangiopericytoma.

Localized fibrous tumor of the pleura is a rare condition. Most follow a benign course and they are round as an incidental finding during routine chest X-ray. A small proportion of these tumors are malignant and have characteristic clinical and histopathological features. In this paper, we report three cases of localized fibrous tumors of the pleura, one malignant associated with asymptomatic hypoglycemia, the others benign. In a malignant case, the tumor was reseated through thoracotomy and the hypoglycemia was relieved immediately. In two benign cases, tumors on small pedicles were resected using video-assisted thoracic surgical technique.
