Core Tip

Core Tip: This report describes a 44-year-old female patient with metastatic ductal breast cancer (BC) in the ascending colon who underwent laparoscopic radical right hemicolectomy. Colonic metastasis from BC (CMBC) is extremely rare. The case is presented along with a literature review. The results of our study remaindered that CMBC should be highly cautious in patients with a previous history of breast carcinoma, especially triple negative BC. Attention should be paid to the gastrointestinal symptoms during follow-up for BC. A detailed examination including immunohistochemical analysis of endoscopic biopsies prior to surgery should be performed.
