Cytogenetic analysis of two adult fibrosarcomas revealed clonal chromo
somal rearrangements including unbalanced translocations between chrom
osomes 2 and 19, with the same segment, 2q21-qter, translocated onto 1
9p13 in one tumor and 19q13 in another; and partial monosomy of 10q du
e to add(10)(q22) and del(10)(q22q25) seen in one tumor each. This is
the first description of nonrandom chromosomal changes in adult fibros
arcoma. (C) 1998 Wiley-Liss, Inc.
