Endometrial polyps with predominant stromal component are characterized by a t(6;14)(p21;q24) translocation

Cytogenetic investigation of endometrial polyps revealed the presence of a t(6;14)(p21;q24) as the sole abnormality in three cases. All tumors showed a histopathological pattern of predominant stromal hyperplasia with scarce representation of glandular elements, suggesting that a cytogenetic subgroup characterized by the t(6;14) translocation can be associated with endometrial polyps with a preponderant component of mesenchymal origin.
