Recurrent Prolapsed Giant Uterine Polyp Comprised of Adenomyotic Cysts

The commonest pathologic diagnosis of large prolapsed polyps is leiomyoma. Benign or malignant adenomyomatous polyps follow. Adenomyotic cyst is a rare form of adenomyosis. To our knowledge, a recurrent prolapsed giant uterine polyp comprised of adenomyotic cysts and with different pathogenesis from the original polyp has not been reported in the literature. This case report describes a 29 year old woman with meno/metrrorrhagia, who was found to have a large recurrent uterine polyp prolapsed into the vagina at two and a half years after removal of an initial large uterine polyp. The initial polyp was a large uterine leiomyoma protruding through cervix. The recurrent giant polyp was comprised of adenomyotic cysts. Thus, this case report demonstrates that a prolapsed giant polyp of the uterine corpus can be caused by enlarged adenomyotic cysts inside the polyp. The pathogenesis of a recurrent uterine polyp may be different from that of the initial polyp.
