title: Endometrial osseous metaplasia-a rare presentation of polymenorrhagia: a case report.
abstract: Endometrial ossification is a rare entity in which bones are found in the uterus. Exact aetiopathogenesis is not known but the most accepted theory is metaplasia of stromal cells into osteoblast cells result in the formation of bones. The possibility of malignant mixed mullerian tumour should be in the mind of clinician and pathologist while making diagnosis. We hereby report an extremely rare case, which is among very few reported cases in the world, in which endometrial ossification presented in a perimenopausal female with polymenorrhagia. A 41-year-old multiparous patient presented with irregular bleeding per vaginum for the past two years. She was found to be a case of endometrial calcification with osseous metaplasia with presence of bones varying from 7mm - 1.5 cms size in the uterine cavity. She was successfully managed by total abdominal hysterectomy.
