Metastases of breast cancer to the gastrointestinal tract (GIT) are rare. We here report of a 52-year-old woman, in whom breast invasive lobular carcinoma (ILC) metastasized to the stomach and rectum more than 10 years later. Gastric and rectal metastasis became evident after 12 and 13 years, respectively, of the initial treatment of breast cancer. Immunohistochemistry and histological examination confirmed the mammary origin of the digestive malignancy, because of the histopathological similarities between these metastatic lesions and the initial breast cancer. We chose chemotherapy for these metastatic lesions. Treatment should be decided based on the patient’s age, clinical manifestation, previous treatments, and treatment availability. Although very rare, GIT-metastasis of the breast cancer after a long interval (for example, up to more than 20 years) can occur: ILC is the most frequently observed. We must aware that GIT-metastasis can occur long after the initial treatment of breast cancer. This justifies prolonged surveillance for patients treated for early ILCs.
