Uncommon metastases of invasive lobular breast cancer to the endometrium: a report of two cases and review of the literature
AbstractAlthough it is known that breast cancer can metastasize to many organ sites, metastasis to the uterus is uncommon and usually occurs during widespread metastatic disease. Lobular carcinoma is not the most common histological subtypes of breast carcinoma, but it is the most frequent histologic type that causes gastrointestinal, gynecological and peritoneal metastases. The main symptoms of the uterine metastasis depend on the anatomic involvement site. Abnormal uterine bleeding is by far the most important symptom.We highlight the importance of the follow up of patient with breast cancer. A rapid endometrial sampling for confirmation of the diagnosis, should be performed when the routine gynecological follow-up revealed any abnormality. We report two original observations of endometrium metastases of invasive lobular carcinoma of the breast which we detected during follow-up.
