Cytogenetic and fluorescence in situ hybridization (FISH) studies in a case
of follicular lymphoma grade III showed a "jumping translocation" of chrom
osome 1q21-qter to chromosomes Xq28 and 18q23, which resulted in a partial
trisomy 1q as the only chromosome aberration. This case represents, to the
best of our knowledge, the first report of a jumping translocation in a mal
ignant lymphoma occurring as the sole aberration. (C) Elsevier Science Inc.
