Uterine adenosarcoma diagnosed following hysteroscopic resection of an intrauterine tumour

Uterine adenosarcoma is a mixed müllerian tumour consisting of a benign epithelial component and a malignant stromal component. It is a rare tumour that represents 8% of uterine sarcomas. We present a case of a 61-year-old woman who underwent a surgical hysteroscopy for postmenopausal metrorrhagia and thickened endometrium detected by ultrasonography. The pathologic diagnosis of the tumour removed by hysteroscopy was uterine adenosarcoma. The description of this case provides an opportunity to review the literature on uterine sarcomas diagnosed by surgical hysteroscopy.
