Breakpoints in benign lipoma may be at 12q13 or 12q14

Chromosomal investigations in two unrelated lipoma samples are reported. The breakpoint involving 12q in chromosomal rearrangements could be assigned to band 12q13 in one case and 12q14 in the other case. Evidence is provided that cytogenetically distinct breakpoints on 12q may be found in lipoma cells, resolving previous disagreements based on interpretational difficulties.
