title: Trisomy 4 as the sole cytogenetic abnormality in a Waldenström macroglobulinemia.
abstract: We report a case of Waldenström macroglobulinemia with trisomy 4 as the sole cytogenetic abnormality. Trisomy 4 has been reported previously in Waldenström macroglobulinemia, but only in conjunction with multiple chromosomal aberrations. Trisomy 4 has been reported in other hematologic malignancies including acute myeloid and lymphoid leukemias.
