Endometrial polyp: another benign tumor characterized by 12q13-q15 changes

Abstract

Clustering of aberrations to specific chromosome regions of benign tumors may indicate the location of genes related to the proliferative process. Although few endometrial polyps have been cytogenetically investigated, 6p21 band appears to be involved consistently in the chromosome changes. We report two cases of this type of benign tumor with chromosome rearrangements in 12q14-15, allowing identification of a second cytogenetic subgroup in endometrial polyps.
