Lobular carcinoma metastasis to endometrial polyp unrelated to tamoxifen : Report of a case and review of the literature

Endometrial polyps are rare sites for metastatic breast carcinoma. Such cases have mostly been reported in tamoxifen-related polyps. We report a case of lobular carcinoma with metastasis to an endometrial polyp in a patient with no history of tamoxifen therapy. The histological features of the polyp in our case closely mimicked those of tamoxifen-related polyps, emphasizing the fact that although characteristic-these features are not specific for tamoxifen. This case also reiterates the need for careful evaluation of endometrial polyps, since inconspicuous deposits of lobular carcinoma can easily be missed.
