An unwelcome guest: two cases of colonic metastatic lobular breast cancer

Abstract

Metastatic spread of invasive lobular breast cancer is rare. It can have a delayed and varied presentation that can mimic other bowel pathologies, such as colorectal cancer and inflammatory bowel disease, making its diagnosis difficult. In this study, we present two patients who required colonic resection due to malignant obstruction caused by metastatic invasive lobular carcinoma of the breast.
