Cytogenetics of multiple uterine leiomyomas, parametrial leiomyoma and disseminated peritoneal leiomyomatosis.
Using banding techniques the chromosomes were studied in 15 leiomyomas. The material comprised nine uterine myomas from one patient, one parametrial leiomyoma from a second patient and five tumors from a third patient with disseminated peritoneal leiomyomatosis. The results were considered together with pooled data from the literature. From this it could be concluded that: (1) each leiomyoma was the product of a separate clonal development; (2) different leiomyomas from the same patient sometimes showed an identical abnormal stemline (possibly because of etiological influences); (3) uterine and extra-uterine leiomyomas seemed to follow similar evolutionary pathways in their chromosomal progression.
