title: Nuclear hypersegmentation in the myeloma cells of a patient with multiple myeloma.
abstract: A patient with multiple myeloma in whom the bone marrow plasmablasts showed extensive lobulation is described. In addition to numerous lobes, some of the nuclei had a cerebriform appearance, similar to that observed in Sézary cells. The possible relation of this phenomenon to the expression of the altered function of the malignant cells is discussed.
