The initial cytogenetic analysis of a biphasic synovial sarcoma revealed complex anomalies involving six different chromosomes: 46,Y,t(X185;4)(p11;q11;p13;q12),t(2;5)(q35;q11). After fluorescence in situ hybridization (FISH) analysis, using chromosome X‐specific plasmid library and YAC probes, the situation appeared to be even more complex, with an insertion of part of the X chromosome short arm into the der(5)t(5;18). In spite of these complex chromosomal rearrangements, the Xp11 breakpoint could be mapped to within the ornithine aminotransferase ( OAT )LI cluster, very similar to that reported previously for the standard t(X 18)(p11;q11) in synovial sarcomas. These findings suggest common pathogenetic pathways in these cytogenetically different but morphologically similar tumors. Genes Chrom Cancer 9:288‐291 (1994). © 1994 Wiley‐Liss, Inc.
