Cotyledonoid leiomyoma of uterus.

Cotyledonoid leiomyoma is very rarely described variant of benign uterine leiomyoma. Roth et al. [1] reported a series of four cases of leiomyoma characterized by alarming extra uterine growth with a dissecting myometrial component. Because of its striking resemblance to placenta, the term cotyledonoid dissecting leiomyoma was coined for this peculiar variant. It is also called Sternberg Tumor in recognition of contribution by the late William H. Sternberg.
