Osseous Metaplasia of the Endometrium: A Rare Entity.

This paper presents a case of osseous metaplasia of the endometrium, a rarely encountered disease. Metaplasia is described as a change of one epithelium into another epithelium due to some triggering factor. In this case, endometrium is converted into osseous spicules. It might be followed by an abortion presenting with Infertility or chronic endometritis or metabolic disorder like hypervitaminosis D or electroexcision of cervix, prolonged estrogen therapy, which is generally diagnosed by hysteroscopy and ultrasound and certified by histopathological examination. We report the case who presented with osseous metaplasia 17 years post-menopausal and 34-years post-abortion, the longest ever reported in the literature so far.
