Abstract Introduction Neoplasms of the placenta are uncommon. Tumors arising from the placental tissue include two distinct histological types the benign vascular tumor chorangioma and very rarely choriocarcinoma. Benign leiomyomas in contrast are very common tumors of the uterine wall and occur in to of all pregnant women. However the incorporation of uterine leiomyoma into the placenta is exceptional and raises the question of its origin. This case is possibly the first report on this kind of a placental tumor which has been examined using both immunohistochemistry and chromosome .
