For about 20 years we have known from cytogenetic studies that there is a clonal cell population in Hodgkin's disease. Most karyotypes are complexly aberrant and chromosome numbers typically lie in the hyperploid range. Some chromosome regions seem to be preferentially involved, but a chromosome aberration specific for Hodgkin's disease has not yet been determined. Although the existence of a clonal cell population is evident from these cytogenetic studies, there is still an ongoing debate, whether in all cases the pathognomonic Hodgkin and Reed-Stemberg cells belong to one single aberrant clone and thus represent a monoclonal proliferation. This article reviews the current knowledge on cytogenetics in Hodgkin's disease. Moreover, our recent data from simultaneous immunophenotyping and interphase cytogenetics (FICTION) are introduced into the passionate discussion on the monoclonality of the Hodgkin and Reed-Sternberg cells.
