Cystic adenomyosis spreading into subserosal-peduncolated myoma: How to explain it?

AbstractIntroductionCystic adenomyosis is a rare variant of adenomyosis characterized by well- circumscribed cavitated endometrial gland and stroma located within the myometrium. The cysts usually measure≥1cm in diameter, contain a “chocolate-colored” fluid and do not open into the overlaying endometrium.Case presentationWe present a case of a peduncolated-subserosal cystic adenomyoma, namely cystic adenomyosis, correlated with pelvic MR imaging, laparoscopic surgery technique and histopathology findings.ConclusionsIn this case, the peculiar growth pattern of cystic adenomyosis in a myoma represents a singular condition rarely reported in the medical literature. We therefore support the pathogenetic theory that the disease might have been caused by direct proliferation of endometrial cells within a peduncolated- subserosal myoma
