title: Metastasis from breast carcinoma to endometrial polyp.
abstract: Metastasis of a breast carcinoma to an endometrial polyp is extremely rare, with only ten cases having been reported in the literature up to now. We present the case of a 60-year-old woman with invasive ductal carcinoma who complained of vaginal bleeding. She underwent hysteroscopy with biopsy. Microscopic examination revealed an endometrial polyp which contained foci of adenocarcinoma. The morphologic features of the tumor were identical to the original breast carcinoma.
