title: Ph chromosome and B-cell malignancy-associated chromosomal aberrations in non-leukaemic immunoblastic B-cell lymphoma.
abstract: A 62-year-old female with a microK phenotypic immunoblastic B-cell lymphoma with bone marrow involvement but without leukaemia is reported. Bone marrow cells, cytogenetically studied at diagnosis, showed a Philadelphia chromosome due to a (9p;22q) translocation, deleted chromosomes 3 and 6, a 14q+ marker, and two extra chromosomes 18. The Ph chromosome is previously only once reported in a well-characterized B-cell lymphoma, whereas the latter aberrations are common findings in B-cell malignancies.
