abstract ={Gastrointestinal metastasis from primary breast carcinoma is very uncommon, with less than 1% of breast
carcinomas metastasize to the gastrointestinal tract but anorectal involvement is even rarer. These metastatic
lesions can lead to diagnostic challenge for clinicians as they can mimic primary colo-rectal cancer due to
the lack of diagnostic signs. The increase of patient survival could lead to an unusual late resumption of
metastatic disease, often for a long-time occult. Nowadays, an almost completely absent literature is unable
to suggest diagnostic pathways capable of predicting this type of disease evolution. We present the case of
a 76-year old woman who underwent treatment for an infiltrative lobular carcinoma of the breast who
developed metastasis of the anal canal 11- years later. A literature review was performed.
