<unk> <unk>  round cells of Ewing Sarcoma Display of<unk>  round<unk>  cells characteristic of desmoplastic<unk>  round cell tumour. In histopathology, a<unk> r (abbreviated SBRCT), also known as a<unk> -round-blue-cell tumor (SRBCT) or a<unk> -round-cell tumour (SRCT), is any one of a group of malignant neoplasms that have a characteristic appearance under the microscope, i.e. consisting of<unk>  round cells that stain<unk>  on routine H&E stained sections. These tumors are seen more often in children than in adults. They typically represent undifferentiated cells. The predominance of<unk>  staining is because the cells consist predominantly of nucleus, thus they have scant cytoplasm. __TOC__
