Primary intrathoracic neoplasms occur frequently, and the most frequent intrathoracic tumors are of pulmonary or bronchogenic origin. Second in frequency are mediastinal tumors, and least frequency or comparatively rare are the neoplasms arising from the wall of the thorax and extending into the thoracic cavity. Of all intrathoracic tumors, fibroma is extremely rare. Recently, we have experienced a huge rapid growing intrathoracic fibroma originating from thoracic wall, which is removed successfully and confirmed histopathologically. Authors present one case of fibroma and discussion with a brief review of the relevant literatures.

We report a case of invasive pulmonary aspergillosis invading the mediastinum and the left atrium. A 70-year-old woman was hospitalized for dyspnea. She had been well controlled for her diabetes mellitus and hypertension. The chest X-ray disclosed mediastinal widening, and the computed tomography scan of the chest showed that there was a large mediastinal mass and this lesion extended into the left atrium and right bronchus. The cardiac echocardiography showed that a huge mediastinal cystic mass compressed in the right atrium and a hyperechoic polypoid lesion in the left. The pathology from the bronchoscopic biopsy observed abundant fungal hyphae which was stained with periodic acid-Schiff and Gomori's methenamine silver. Despite the treatment with antifungal agents, she died from cardiac tamponade after three months. Invasive pulmonary aspergillosis, which involves the mediastinum and the heart, is very rare in immunocompetent patients.

Complete resection of an apicoposterior mediastinal mass is essential due to the mass effect, which exerts pressure on adjacent organs. Recently, the use of minimally invasive surgery has had many advantages. In this report, we describe a case in which a large apicoposterior mediastinal hypervascular mass was managed using a purse-string suture technique during robotic-assisted thoracoscopic surgery (RATS). The patient, a 77-year-old woman, was diagnosed with a 6.2-cm apicoposterior mediastinal hypervascular solid mass originating from the branches of the right subclavian artery. The patient underwent RATS for treatment. To obtain an adequate view of the apex of the thoracic cavity, a needle aspiration was performed, followed by the application of a purse-string suture technique. This was done to reduce the size of the tumor and to prevent catastrophic events such as seeding or spillage of the cystic mass. The mass was histopathologically diagnosed as a schwannoma. The patient was discharged on the first postoperative day without experiencing any complications.

Cystic hygroma is a benign tumor of lymphatic origin encountering most frequently in young children, and composed of softly fluctuated mono or multilocular cystic masses which developed from embryonic outpouching of the venous system. The majority of these tumors are found at the anterolateral neck region particularly posterior .triangle, and occasionaly axilla, mesentery and spleen etc. In the mediastinum, the incidence of hygroma is very rare and also of mediastinal neoplasms. Recently, we have experienced 2 cases of mediastinal cystic hygroma connected up lateral neck and to anterior chest wall respectively, which were surgically removed successfully and confirmed histopathologically. Authors present the cases and discussion with a brief review of the relevant literatures.

Primary malignant melanoma of the mediastinum is extremely rare : To date, there have been only 8 cases reported in the literature. We report a case of a 50-year-old woman presented with an anterior mediastinal mass. The mass invaded the lung parenchyme of right upper lobe, which was wedge-resected with the mass. Microscopically, spindle or polygonal tumor cells with prominent nucleoli and intracytoplasmic melanin pigments are characterized and Fontana stain confirmed the presence of melanin pigment. Immunohistochemical studies showed diffuse positive staining for HMB45, S100 protein and vimentin, which further suggested melanoma.

Ectopic mediastinal parathyroid adenomas or hyperplasias account for up to 25% of primary hyperparathyroidism cases. Most abnormal parathyroid glands are found in the superior mediastinum within the thymus and can be removed through a cervical incision; however, a few of these glands are not accessible using standard cervical surgical approaches. Surgical resection has traditionally been performed via median sternotomy or thoracotomy. However, recent advancement in video-assisted thoracic surgery techniques has decreased the need for sternotomy or thoracotomy to remove these ectopic parathyroid glands. Here, we report a successful case of video-assisted thoracoscopic removal of a mediastinal parathyroid adenoma.

Neurogenic tumors are common in posterior mediastinal tumors. In most cases, tumors were accidentally showed on simple chest X-ray. In some cases, they were presented by symptoms which were induced by nerve compression or airway compression. But as in our case, neurogenic tumor with spontaneous hemothorax is very rare. A 45-year-old man admitted to emergency room of other hospital because of acute right chest pain and dyspnea. A chest X-ray showed a right pleural effusion. Hemothorax was diagnosed after closed thoracostomy. Following chest CT showed posterior mediastinal mass. The patient was transferred to our hospital. T spine MRI showed dumbbell shaped mass. Diagostic impression was neurogenic tumor. The pathologic result was neurilemmoma after surgical resection.

Chordomas are slowly growing and rare malignant tumors arising from the remnants of the notochord. Furthermore, intrathoracic chordomas presenting as a posterior mediastinal tumor account for only 1∼2％ of all reported chordomas. Incomplete resection of these tumors can lead to local recurrence, distant metastasis and result in a poor outcome, but complete remission can be expected with complete resection and adjuvant radiotherapy. We report a case of thoracic chordoma presenting as a posterior mediastinal tumor which was successfully treated with complete resection and adjuvant radiotherapy without recurrence and distant metastasis for 2 years.

Pneumocephalus after thoracoscopic excision of a mediastinal mass is a very rare complication. It presumably occurs due to dural injury near the spinal root and development of a subsequent subarachnoid-pleural fistula. A 60-year-old woman complained of nausea and headache after thoracoscopic excision of a posterior mediastinal mass. She was diagnosed with pneumocephalus by brain CT and recovered with supportive management.

Extramedullary hematopoiesis is a common compensatory mechanism of chronic anemia, but an asymptomatic posterior mediastinal mass is rarely diagnosed as an extramedullary hematopoiesis after surgical resection. The differential from neurogenic tumors is important, but fine needle aspiration biopsy is not recommended because of the difficulty of approach and risk of bleeding. Although diagnosis and treatment can involve resection via thoracotomy, video-assisted thoracic surgery may also be a useful strategy. We performed video-assisted thoracic surgery on a 59-year-old man for posterior mediastinal extramedullary hematopoiesis, with no evidence of recurrence or related hematologic diseases.
