    Journal: Cancer Genet Cytogenet; 1986 Apr 01; 21(3):185-208. PubMed ID: 3004699.
    Abstract:
    Small, round, blue-cell tumors (SRCT), including rhabdomyosarcoma, Ewing's sarcoma of bone and soft tissue, mesenchymal chondrosarcoma, small cell osteosarcoma, hemangiopericytoma, neuroblastoma, peripheral neurectodermal tumor (peripheral neuroepithelioma of bone and soft tissue), and the malignant small cell tumor of the thoracopulmonary region described by Askin (Askin's tumor), are often difficult to distinguish by light microscopy. We have evaluated the cytogenetics of these tumors by studying 24 tumor explants in short-term culture and 22 tumor cell lines. In Ewing's sarcoma (a tumor of unknown histogenesis), and in peripheral neuroepithelioma and Askin's tumor (tumors with evidence of neural origin), we have observed an indistinguishable t(11;22) translocation.
