Mediastinal liposarcoma (ML) is a rare mesenchymal tumor, accounting for less than 1% of mediastinal tumors. They have a slow growth, so they may not give symptoms for a long time, until the tumor produces compression of close structures. The treatment of choice is surgery, which can be combined with chemo-radiotherapy. We present a case in which the diagnosis of a ML was made in a 30-year-old ...

mediastinal teratomas are usually asymptomatic tumors, located most commonly in the anterior mediastinum. very rarely, such tumors may rupture into the tracheobronchial tree, lung, pleura or pericardium. computed tomography (ct) is helpful in the diagnosis and differentiation of ruptured and unruptured tumors. we report a case of ruptured anterior mediastinal teratoma in a 20-year-old female pr...

Improvements in cytologic techniques have made needle biopsy much more helpful in diagnosing mediastinal masses. We have added thoracoscopy to the surgical armamentarium. Tumor markers facilitate accurate diagnosis. In the field of imaging, cysts can now be identified almost certainly and aspirated. Magnetic resonance imaging has changed the workup of patients with posterior mediastinal masses....

Although gastrointestinal stromal tumor (GIST) is the most common mesenchymal neoplasm of the gastrointestinal tract, it rarely arises from the esophagus and is thus very rarely the cause of a mediastinal mass. We report a case of esophageal GIST presenting as a mediastinal mass in a 59-yearold male. If such a tumor has extremely exophytic growth, it may result in a huge mediastinal mass withou...

Mediastinal granulocytic sarcoma (GS) is a relatively rare disease. We experienced a case of acute myeloid leukemia (AML) that took a rapid turn for the worse after the resection of a mediastinal GS. A healthy 60-year-old man had been in good general health all his life, but was diagnosed with a mediastinal tumor by his family physician and was referred to our department. The patient underwent ...

Unicentric Castleman's disease is a rare, benign lymphoproliferative disorder that is curable with surgical resection. However, significant bleeding often occurs during surgery because of tumor hypervascularity. We herein present a case of hyaline-vascular-type mediastinal unicentric Castleman's disease, successfully resected using video-assisted thoracoscopic surgery with preoperative emboliza...

The granular cell tumor (GCT) occurs extremely rarely in the mediastinum. Few mediastinal GCT cases have been reported in Japan or other countries. Here, we report a case of a 24-year-old man with superior mediastinal GCT. The mass was located just above the aortic arch. It was firm, oval in shape, and well encapsulated. The tumor was removed completely with video-assisted thoracoscopic surgery...

  Although the most common hematological disturbance in thymoma is pure red cell aplasia, pancytopenia is a very rare paraneoplastic syndrome in this disorder. We only found one case in literature reviews. We report a 36 year old female with an anterior mediastinal mass and severe pancytopenia. With a mediastinotomy incision, biopsy of the tumor was obtained. The report of the pathologist was t...
