title: Cytogenetic characterization of ten malignant fibrous histiocytomas.
abstract: We examined 10 malignant fibrous histiocytomas (MFHs) using metaphase preparations. Six tumors showed clonal structural and/or numerical chromosomal aberrations, and four tumors had normal karyotypes. For the most part, chromosomes 1, 3, 6, 9, 12, 16, 18, and 20 were involved in structural aberrations. The breakpoint regions most frequently were in 1p32, 3p25, and the centromeric region of chromosomes 1 and 16. There was a conspicuous loss in chromosome 18. We detected ring chromosomes in two tumors. One tumor showed a high percentage of near-haploid cells. Our results show many parallels to data which have already been published. MFHs include a broad spectrum of tumors of widely different histology and clinical course. So it is not surprising to find a cytogenetic diversity of chromosomal aberrations in this study.
