Endometrial osseous metaplasia (EOM) / Osseous metaplasia of endometrium is a very rare pathological entity which can cause infertility and menorrhagia in females. We present a 30 year old female presenting to the obstetrics and gynaecology outpatient department with chief complaints of infertility. Her menstrual history was normal. She did not have any other significant complaints. Her laboratory investigations were within normal limits. A pelvic ultrasound was performed which showed a significantly thickened endometrium. Following which an endometrial curretting was done and the same was sent to histopathological department. Grossly the specimen was received in multiple fragments aggregating to 2cc. Among the soft tissue fragments, bits of hard and gritty fragments were also noted. Microscopy showed tubular endometrial glands admixed with endometrial stroma and numerous mature lamellar and woven bony trabeculae. No evidence of granuloma/ hyperplasia/ malignancy noted in the multiple sections examined.
