Abnormal karyotypes from 13 human cases of Ewing's sarcoma are reported in this paper. The t(11;22) was seen in 9 cases, with 2 additional cases containing only a del(22). Other abnormalities included trisomy of 1q, translocations to 19p13, deletions of 3p and 6q, and homogeneously staining regions.
