ABSTRACT

Bone within the uterine cavity is an unusual finding in women with secondary infertility, and is usually associated with a past history of termination of pregnancy.The etiology is unknown, but theories include retained fetal bone and osseous metaplasia of endometrial tissue. We describe a case of infertility patient, had history of surgical termination of pregnancies. Histological exami-nation of the curettage material revealed bone marrow formation, a phenomenon that has been merely reported twice previously in the literature.
