Synovial sarcoma is a malignant soft-tissue tumor that most commonly occurs in the extremities of young adults. There have been several cases of synovial sarcomas of the pleural and lung reported, but synovial sarcoma arising from the chest wall in childhood is very rare. Here we report a case of synovial sarcoma arising from the chest wall in a 3 year-old female patient. The tumor was completely resected. No adjuvant therapy was given. The patient is well 3 years after the operation.

Pleuropulmonary blastoma (PPB) is a rare intrathoracic neoplasm, found solely in childhood. The usual symptoms are dyspnea, chest discomfort, recurrent respiratory infections, fever, dry cough, and chest pain. The progress of PPB is usually aggressive and its progress is generally poor. Lymphatic spread to the hilar and mediastinal nodes can occur Distant metastasis is found in brain, bones, and intra-abdominal organs. Surgical resection is the treatment of choice. When the disease Is too extensive for surgical resection, neoadjuvant chemotherapy can be used. We report 2 cases of pleuropulrnonary blastoma in children successfully treated with multimodal therapy.

Background: A better understanding of the histopathology and molecular biology of lung cancer might improve our capability to predict the outcome for any individual patient. The purpose of this study was to evaluate several histopathologic and molecular markers in order to assess their prognostic value in stage I non-small cell lung cancer. Materials and Methods: One hundred ten patients at the Kyungpook National University Hospital were enrolled in the study. Histopathologic factors and molecular markers were selected. Results: Univariate analysis showed that the T stage, differentiation, visceral pleural invasion, and survivin expression were significantly associated with recurrence. Multivariate analysis demonstrated that differentiation and survivin overexpression emerged as independent prognostic factors of recurrence. Conclusion: In resected stage I non-small cell lung cancer, poor differentiation and survivin overexpression have been identified as independent predictors of poor disease-free survival.

Pericardial mesothelioma is a rare neoplasm in dogs. This report describes a case of pericardial mesothelioma in a 13-year-old Shih Tzu that presented with a clinical history of dyspnea. Hemorrhagic pericardial effusion and chylous pleural effusion with reactive mesothelial cells were identified by radiograph and cytology. Necropsy revealed multiple round nodules throughout the pericardium and regional lymph nodes in addition to chylothorax. Histopathology revealed invasive neoplasm on the pericardial surface with metastasis to the lymph nodes. The neoplastic cells were immunopositive to both cytokeratin and vimentin. Diagnosis of pericardial mesothelioma with regional lymph node metastasis was made.

The solitary fibrous tumor (SFT) is a mesenchymal neoplasm that is described as spindle-shaped tumor cells on a collagenous background originating from pleural tissues. Recently, extrapleural SFT has been reported in nearly all sites, including the sublingual gland, parotid gland, nasal cavity and paranasal sinuses. Complete surgical excision is primary treatment for SFT, but diagnosing SFT is not often made until immunohistochemical evaluation after surgical resection. We report that the patient, 45-year-old male, was considered as a case of inflammation polyp arising from left nasal cavity with initial biopsy, however, it has turned out to be SFT after surgical treatment.

The occurrence of hiatal hernia after total gastrectomy with Roux-en-Y reconstruction is rare. We report the case of a 76-year-old man who presented with dyspnea, vomiting, and fever around 8 days after total gastrectomy with Roux-en-Y reconstruction. Abdominal computed tomography revealed a hiatal hernia containing part of the small intestine in the left thoracic cavity. Emergent reduction and repair of the hiatal hernia were performed later. Operative findings revealed that the Roux limb was incarcerated in the left pleural cavity. Esophagojejunostomy leakage, perforation of the small intestine with transient ischemic change, and pyothorax were also found. Thus, feeding jejunostomy, thoracoscopic decortication, and diversion T-tube esophagostomy were performed. Considering that the main cause of hiatal hernia is blunt dissection with division of the phrenoesophageal membrane, approximating the crus with 1 or 2 figure-8 sutures, according to the size of the defect, to prevent the incidence of hiatal hernia after total gastrectomy may be performed.

Paraneoplastic limbic encephalitis (PLE) is a rare syndrome characterized by memory impairment, affective and behavioral disturbances and seizures. Among many different neoplasms known to cause PLE, small cell lung cancer (SCLC) is the most frequently reported. The pathogenesis is not fully understood but is believed to be autoimmune-related. We experienced a patient with typical clinical features of PLE. A 67-year-old man presented with seizure and disorientation. Brain magnetic resonance imaging demonstrated high signal intensity in the bilateral amygdala and hippocampus in flair and T2-weighted images suggestive of limbic encephalitis. Cerebrospinal fluid tapping revealed no evidence of malignant cells or infection. Positron emission tomography/computed tomography showed a lung mass with pleural effusion and a consequent biopsy confirmed the diagnosis of PLE associated with SCLC. The patient was subsequently treated with chemotherapy and neurologic symptoms gradually improved.

Background : Solitary fibrous tumors of the pleura (SFTP) is one of rare neoplasms that originated from submesothelial mesenchyme. Clinical course or extent of surgical resection is not well known. Material and Method: We retrospectively reviewed all the clinical records of the patients who had undergone surgical resection of benign and malignant SFTP, Result: Twenty two (male female 14 : 8) patients were enrolled and mean age was 50.2(range 25∼83). Number of symptomatic patients at the time of diagnosis was 13 (59%) and the most common symptom was dyspnea. Operative approach was carried out through thoracotomy (n=14) or video-assisted thoracic surgery (n=8). Mass excision was performed in 12 cases and en bloc resection including adjacent structure in 10 cases. In all cases complete resection was performed. There was no operative mortality. Malignant SFTP were 11 cases and benign SFTP 11 cases. Local recurrences (n=2) or distant metastasis (n=6) occurred only in malignant SFTP. Conclusion: Number of symptomatic patients, on bloc resection, and recurrence was more in malignant SFTP. Although complete surgical resection is known as treatment of choice for SFTP, further study should be performed about systemic therapeutic modalities pre- or postoperatively to control recurrence and metastasis.

Solitary fibrous tumor (SFT) is an uncommon spindle cell neoplasm that is usually presented as a pleural origin localized tumor. There are few cases, found in thyroid. Twenty six cases found in thyroid have been reported since 1993, and two of these were malignant. We report another malignant case in this study; a 55 years old man visited out-patient clinic due to palpable mass of anterior neck, and pathologically diagnosed as malignant SFT of thyroid after surgical resection. In this study, we focus on the clinical features of this uncommon disease along with other literature reviews.

We present a case of a 47-year-old woman with benign solitary fibrous tumor of the pleura originated in the diaphragm which was discovered incidentally on a chest radiograph. Chest radiograph, sonograph, computed tomographic scan and magnetic resonance image studies proved a well circumscribed and lobulated fibrous tumor of the pleura. During the subsequent right thoracotomy, the tumor was found to be encapsulated and consisted of firm mass. It was connected to the diaphragm with $5{\times}4$cm area by pedicle. Most of the tumor was free of adhesion. It was excised completely together with attached diaphragm. The tumor measured $23.5{\times}13.5{\times}8.0$cm and the pathologic diagnosis was benign solitary fibrous tumor and the attached diaphragm was free of disease.
