INTRODUCTION
Carcinosarcoma is a malignant mixed mesodermal neoplasm accounting for less than 1% of all ovarian tumors. It is an aggressive tumor, composed of both carcinomatous and mesenchymal components. Ovarian carcinosarcomas are about three times less prevalent than those of the uterus [1]. To the best of our knowledge, less than 400 cases of ovarian carcinosarcomas have been reported in the literature and only 10% of them are bilateral [2,3]. In this paper, we report a new case of bilateral ovarian carcinosarcoma in a 52-year-old woman. Our aim was to recall the clinical and pathological features of this rare and distinct neoplasm.
