Ovarian hemangiomas are rare tumors. Most of them are asymptomatic and of the cavernous type. The ovaries have a rich vascular supply and the rarity of vascular tumors in the ovary is therefore surprising. Although often found incidentally during the surgery, these lesions may rarely be associated with systemic manifestations. Here, we report two cases of cavernous ovarian hemangiomas. One was accompanied by with an endometrial carcinoma in a patient who presented with postmenopausal bleeding, and the other was found incidentally during the histopathological examination of the hysterectomy and bilateral salphingo-oophorectomy specimen that was performed for leiomyoma uteri.
