摘要
Cytogenetic analysis of a malignant giant cell tumor of the sacrum from a 62-year-old female revealed the following chromosomal complement: 47,XX,-1,-11,+22,del(2)(p22),t(7;7) (p22;q32),+ der(1)t(1;11;21)(p32;q13;q22),+ der(19)t(19;?)(q13.4;?),der(8)t(8;?)(p11;?), der(7)t(17;?)(p13;?). Metaphase cells with 92-127 chromosomes sharing identical structural abnormalities detected in the near-diploid cells were also observed. Several of these abnormalities have previously been described in the benign giant cell tumors supporting a direct relationship between these benign and malignant neoplastic counterparts.
