Lobular carcinoma metastasis to endometrial polyp unrelated to tamoxifen: Report of a case and review of the literature
Abstract:Manipadam MT, Walter NM, Selvamani B. Lobular carcinoma metastasis to endometrial polyp unrelated to tamoxifen. Report of a case and review of the literature. APMIS 2008;116:538–40.
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.
