Rare Metastasis of Invasive Lobulillary Breast Cancer to Endometrium / Myometri: Case Report

1. Abstract
We present a clinical case of unusual course, with a diagnosis of endometrioid adenocarcinoma with myometrial involvement due to multifocal carcinoma of lobular carcinoma of the breast, which is not the most common histological subtype of breast carcinoma, but the most frequent histological type that causes gastrointestinal, gynecologic, and peritoneal metastases. Although female genital tract metastases are clinically important, they are rare, more so metastatic breast cancer metastatic to the uterus, these lesions may present insidious symptomatology and disguise primary cancer. In postmenopausal women, abnormal menstruation should alert physicians to consider the possibility of primary and secondary neoplasms improving the timely diagnosis and treatment of this pathology. It should also be considered that patients with breast cancer who have received tamoxifen may develop not only primary endometrial cancers but may also sometimes present uterine metastases.
