Multiple karyotypic rearrangements, including t(X;18)(p11;q11), in a fibrosarcoma

The tumor stem line of a soft tissue fibrosarcoma, histologic malignancy grade III, had 43 chromosomes with several clonal chromosome aberrations, including the three balanced translocations t(X;18)(p11;q11), t(2;15)(p23;q26), and t(7;22)(q11;q13), two partly identifiable marker chromosomes, der(3)dic(3;?)(p11;?) and der(5), one small marker of unknown origin, and loss of one chromosome #11, #18, #19, and #21.
