title: Karyotypic evolution in a B-cell lymphoma.
abstract: A B-cell lymphoma in the lung of a 59-year-old woman showed a near-pentaploid karyotype and chromosomal changes indicating a t(8;14) in cells from a pleural aspirate. Cells from metastases to the skin and a second pleural aspirate were pseudodiploid, but showed separate further complex cytogenetic changes. Among these was a 14q+ chromosome, but the #8 chromosomes apparently were normal. It is suggested that there was a loss of the derivative 8q- chromosome from the t(8;14) followed by homozygozity of the normal #8 chromosome.
