title: Clonal chromosome rearrangements in a uterine myoma.
abstract: A cytogenetic study of a myoma of uterus with extensive hyaline, myxoid, and cystic degeneration revealed a clonal karyotype with a complex structural rearrangement involving chromosomes #3, #12, #14, #17, and #22. The modal chromosome number of the tumor was 45 due to monosomy #22. Analysis of seven additional myomas of the uterus including five tumors with typical histology and two with degenerative changes showed no clonal abnormalities. Single metaphases with a trisomy and a translocation were detected in two tumors. We conclude that although many uterine myomas appear to have normal karyotypes, clonal chromosome abnormalities are present in some of these tumors.
