Endometrial osseous metaplasia: Clinicopathological study of a case and literature review

Endometrial osseous metaplasia is an uncommon clinical entity with the presence of bone in the endometrium. Most of the cases clinically present with secondary infertility following an abortion. Various theories have been proposed and the most accepted theory is metaplasia of the stromal cells into osteoblastic cells that produce the bone. It is important to distinguish this condition from the mixed mullerian tumor of the endometrium to avoid hysterectomy. Removal of these bony bits leads to spontaneous conception. We present one such case in a 25-year-old female patient presented with secondary infertility.
