Primary Renal Sarcoma is rare tumor comprising only 1% of all renal tumours. Synovial sarcomas are generally deep-seated tumors arising in the proximity of large joints of adolescents and young adults and account for 5-10% of all soft tissue tumours. Primary synovial sarcoma of kidney is rare and has poor prognosis. It can only be diagnosed by immunohistochemistry. It should be considered as a ...

We report a rare case of a primary mediastinal synovial sarcoma. A 44-year-old man had a well-defined tumor in the left posterior mediastinum involving the left lower lobe of the lung, as detected on chest computed tomography, and underwent an en bloc excision and a left lower lobectomy. Grossly, the tumor measured 8.0 cm in the greatest diameter, with a solid and tan-white cut surface. Histolo...

Ewing Sarcoma is the second most common primary bone cancer. To date, only a few cases of cutaneous have been published. We present unique case Sarcoma, which presented as blue to violaceous mass on young woman’s chest. The lesion clinically did not align with previous reports but pathology and immunohistochemical stains confirmed diagnosis. Because may masquerade benign tumors, dermatologists ...

A 22-year-old man with primary osteogenic sarcoma of the superior mediastinum is reported. This case is the second instance of primary osteogenic sarcoma of the mediastinum and the first case of superior mediastina...

Primary sarcoma of the lung and/or pleural cavity is a rare finding accounting for <0.5% of all thoracic malignancies. Histologically, mesothelioma predominates in this subcategory of neoplasms; its relationship to asbestos exposure and cigarette smoking is well documented. Other tumor types include fibrosarcoma, malignant fibrous histiocytoma, angiosarcoma, leiomyosarcoma, synovial sarcoma, an...

OBJECTIVE To report two new cases of Ewing's sarcoma/primitive neuroectodermal tumor of the kidney, one of them with tumor thrombus in cava. METHOD Characterization of two new cases and literature review by PubMed search. RESULTS We report the cases of two men diagnosed with primary renal Ewing's sarcoma, who have been treated with nephrectomy and adjuvant chemotherapy, being in complete ...

Synovial sarcoma occurs predominantly in the soft tissues of the extremities, but is exceedingly rare in the mediastinum. It has overlapping histological and immunophenotypic features with other tumours in the differential diagnosis. We report a case of a patient who had an incidental finding of such a tumour. Because of the rarity of this tumour in the mediastinum, optimal therapy is unknown a...

Synovial sarcomas are generally deep-seated tumors that most often occur in the proximity of large joints of adolescents and young adults. We describe two cases of primary renal synovial sarcoma that were treated successfully by radical nephrectomy. Synovial sarcoma originating from the kidney is extremely rare and the histogenesis is uncertain. Surgical resection and ifosfamide based chemother...

Endometrial stromal sarcoma (ESS) is a relatively rare uterine sarcoma, especially extrauterine ESS. Furthermore, retroperitoneal ESS are extremely rare. Up to now, there are only four cases of primary retroperitoneal ESS reported in the literature. We report one case of primary retroperitoneal undifferentiated endometrial stromal sarcoma after concurrent chemoradiation therapy for cervical can...
