Ovarian adenomyoma following gonadotrophin treatment for infertility

An ovarian adenomyoma developed in a 38-year-old infertile patient following treatment with exogenous gonadotrophins. Laparoscopic excision was performed. Histological examination showed thick muscular bundles resembling myometrium lined with endometrial glands and stroma. Gonadotrophins might be involved in the pathogenesis of extrauterine adenomyoma.
