title: Endometrial metastasis from breast cancer in a patient receiving tamoxifen therapy.
abstract: Tamoxifen (TAM) is known to be associated with several types of endometrial pathologies, e.g. hyperplasias, polyps and endometrial carcinomas, sometimes of special histologic type. Here we report a rare case of endometrial metastasis from a breast carcinoma (ductal carcinoma) discovered during TAM therapy. This occurrence does not suggest that TAM treatment causes endometrial metastases of breast cancer. However, clinicians should be aware of this possibility and provide patients receiving TAM therapy with close gynecologic follow-up using liberal indications for endometrial biopsies.
