Invasive lobular carcinoma (ILC) accounts for almost 15% of all breast carcinomas. The potential of ILC to metastasize to the gastointestinal system is significantly greater than that of invasive ductal carcinoma. Gastric metastasis occurred in the ninth year of the follow-up in a patient who was operated on the right breast due to ILC. The patient was investigated for simultaneous masses in the stomach and colon, and a random mass was found in her right breast.
