[Waldenström's syndrome and chromosome aberrations].

The AA. present a case of Waldenström syndrome with chromosomic alterations. The cytogenetic study demonstrated that 3% of metaphases are represented by maps with 47 chromosomes for a supernumerary sub-metacentric chromosome like the A-3 group. On 12% of euploid maps they found similary the sub-metacentric chromosome a-3 group like (chromosome MG) and, at the same time, the lack of an element of the 18-group.
