title: Consistent involvement of band 12q14 in two different translocations in three lipomas from the same patient.
abstract: We studied cytogenetically three distinct lipomas from a patient with multiple subcutaneous lipomas in the left shoulder area. A breakpoint at 12q14 was involved in structural rearrangements in the three lipomas resulting in two different reciprocal translocations, i.e., t(3;12)(q28;q14) in two and a t(1;12)(q34.2;q14) in the third. These results confirm the consistency of involvement of the breakpoint at 12q14 in lipomas and give support to the hypothesis that multiple lipomas evolve from different stem cells.
