Endometrial Ossification in Infertile Patients — Report of 3 Cases

EDITORIAL COMMENT: We accepted this paper for publication because endometrial bone formation is an interesting pathological condition and its relationship to infertility is of interest. Our only publication on this subject (A) was a case of a woman with secondary infertility who had had a previous termination. In this case the woman became pregnant in the cycle following curettage and removal of the bony fragment in the uterus which was presumably retained fetal tissue. The present case reports are different and the authors have reviewed the other associations of endometrial bone formation reported in the literature including those associated with uterine tumours.
