Rectal Metastases of Breast Carcinoma: A Case Report.

The scarcely reported hematogenous rectal metastases from breast cancer are rare and the diagnosis is challenging. They may be recognized before, concomitantly with, or after the diagnosis of the primary site of breast cancer. Invasive lobular cancer is the histological type more frequently described, and most of the affected patients have a late diagnosis. Tardive recognition is associated with poor outcomes, despite the management options. Endoscopic and imaging evaluations, mainly magnetic resonance studies, are useful, but the anatomopathological findings are mandatory to confirm the diagnostic hypothesis. We describe a middle-aged woman with advanced rectal metastases of unsuspected breast cancer found during the evaluation of manifestations due to intestinal implants. One must highlight long-term follow-up of breast cancers even if seeming in remission. The aim of this report is to enhance the suspicion index of primary health care workers.
