BACKGROUND Many successful attempts at removing benign mediastinal tumors with the video-assisted thoracoscopic technique have been reported, but no formal report has been published regarding malignant mediastinal tumors treated with this technique. We report our preliminary experience with video-assisted thoracoscopic removal of mediastinal tumors, benign or malignant. METHODS Seven patients...

Angiomyolipoma is a common tumor of the kidney but has rarely been found in the mediastinum. We report a case of angiomyolipoma of the posterior mediastinum in a 62-year-old woman. She experienced exertional dyspnea and intermittent cough at admission. Computed tomography indicated a tumor located at the left paravertebral and upper posterior mediastinum and MRI imaging demonstrated a mass with...

Capillary hemangioma is a common benign tumor which can occur everywhere in the whole body, however its occurrence in posterior mediastinum is extremely rare, and to the best of our knowledge less than 20 cases have been reported in the English literature so far. Here in we report a 65-year-old lady who presented with prolonged cough and diagnosed to have a posterior mediastinal mass. Before op...

BACKGROUND Expressions of various biomarkers in non-small cell lung cancer (NSCLC) have been linked with the prognosis and involvement of mediastinal lymph nodes. METHODS In this study, we utilized recursive partitioning analysis (RPA) by using P53, c-erb-B2, and P-glycoprotein (PGP) expressions evaluated by immunohistochemistry to estimate retrospectively the likelihood of the occult N2 medi...

We report a case of papillary carcinoma in a mediastinal ectopic thyroid diagnosed by endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). In this case, the tumor was adjacent to the central airway; therefore, we attempted to perform EBUS-TBNA to obtain specimens for a diagnosis of papillary thyroid carcinoma. Surgical resection was conducted, and histological evaluatio...

INTRODUCTION The aim of this study was to identify the role of surgical resection in the treatment of malignant mediastinal neurogenic tumors in children. MATERIALS AND METHODS Thirty-eight consecutive children, who underwent surgical resection of a malignant mediastinal neurogenic tumor between 1986 and 2004, were included in this study. The tumor cell types were neuroblastoma in 23 patients...

We present 2 resected cases of thymic tuberculosis, which had been preoperatively diagnosed as invasive thymoma, using a thallium-201 ((201)Tl) single photon emission computed tomography ((201)Tl SPECT). [Patient 1] A 74-old-male with a 32-year history of steroid therapy for rheumatic arthritis was diagnosed with an anterior mediastinal tumor by routine chest CT scans after onset of myocardial ...

Accurate assessment of the invasion of intrathoracic structures by stage III thymic tumors assists their appropriate management. The present study aimed to evaluate the efficacy of computed tomography (CT) features for the prediction of stage III thymoma invasion. The pre-operative CT images of 66 patients with confirmed stage III thymic tumors were reviewed retrospectively. The CT features of ...

Solitary fibrous tumors are uncommon spindle cell neoplasms originally thought to be restricted to the pleura. We describe a 62-year-old woman who presented with stridor and an anterior mediastinal mass. At thoracotomy, a 10.5 x 6.5 x 5.5 cm, circumscribed, firm mediastinal mass demonstrated no direct cardiac or pulmonary involvement. The tumor consisted of spindle cells organized in a patternl...

Primary mediastinal liposarcomas are extremely rare conditions often resected through standard median sternotomy or lateral thoracotomy. However, the management of a very huge mediastinal tumor involving hemithorax through these two common surgical approaches is always challenging. Herein, we report a case of applying median sternotomy with a sternum transection plus a right fourth intercostal ...
