A 9-year-old male presented with a renal tumor that showed a cystic structure with calcification on computed tomography. A pathological analysis of the resected tumor suggested clear cell sarcoma of the kidney (CCSK). Thus, this patient suffered atypical CCSK with significant calcification and gross necrosis. A novel chromosomal abnormality was also identified in the tumor.
We report a case of primary clear-cell sarcoma (CCS) in the mediastinum. In October 2011, a 63-year-old man was admitted to our hospital for surgical resection. The tumor was completely excised by video-assisted thoracoscopic surgery. The tumor was well encapsulated and did not invade the pleura. Histological examination led to a final diagnosis of primary CCS in the mediastinum. The patient re...
Clear cell sarcoma is an aggressive soft tissue sarcoma and highly resistant to conventional chemotherapy and radiation therapy. This devastating disease is defined by EWSR1-ATF1 fusion gene resulting from chromosomal translocation t(12;22)(q13;q12) and characterized by melanocytic differentiation. A marine-derived antineoplastic agent, trabectedin, inhibits the growth of myxoid liposarcoma and...
BACKGROUND Clear cell sarcoma of tendons and aponeuroses is a rare, high grade malignant soft tissue tumor resembling melanoma and soft tissue sarcomas. Clinical and Imaging Presentation: The median age at presentation is 27 years and the most common location are the foot and the ankle. MR imaging typically shows a benign looking, well defined, homogenous mass; on T1-weighted MR images, it is u...
Clear cell renal sarcoma is a rare tumor and comprises 4% of primary pediatric malignant renal tumors. It is known as an aggressive tumor with poor prognosis. Clinically and radiographically, it resembles Wilms tumor. We present a case of a child with an abdominal mass that was diagnosed as clear cell sarcoma of her right kidney.
Clear cell sarcoma of soft tissue is a rare, aggressive soft tissue tumor, which is morphologically similar to malignant melanoma but has no precursor skin lesion and, instead, has a characteristic chromosomal translocation. It is critical, yet challenging, to recognize clear cell sarcoma of soft tissue because the outcome is very different to that of metastatic melanoma. We report a case of cl...
