On the issue of differential diagnosis of primary vaginal leiomyosarcoma, benign metastatic leiomyoma with transformation of one node into leiomyosarcoma and primary peritoneal leiomyosarcoma

Abstract

Differential diagnosis of primary leiomyosarcoma of the vagina/omentum, “benign metastatic leiomyoma” with transformation of one node into leiomyosarcoma, primary peritoneal leiomyosarcoma can present certain difficulties. Due to the rarity of peritoneal leiomyomatosis with malig-nant transformation in postmenopausal women, as well as the rarity of vaginal leiomyosarcomas, we present a clinical case of this kind of differ-ential diagnosis based on a pathohistological examination of material obtained during surgery in a woman with a giant pelvic mass.
