RESUMO
Specific chromosome rearrangements in different types of solid tumors have been described recently in a number of studies. However, the frequency and diagnostic importance of these chromosome rearrangements are currently under intensive investigation. The objective of this study is to provide a preliminary report on the types of clonal chromosome abnormalities observed in sarcomas of bone and soft tissues. Included in this report are osteosarcoma [five], synovial sarcoma [three], Ewing sarcoma [two], leiomyosarcoma [one], and spindle cell sarcoma [one]. Cytogenetic analysis revealed clonal chromosome rearrangements in all of the tumors studied. Our findings correlated well with previously reported cytogenetic data on various types of solid tumors
