Background: Metastases of lobular breast cancer are commonly encountered at the level of lungs, bones, brain and liver, whereas lesions in the gastrointestinal tract are rarely seen. Case Report: A case of a patient with metastases in the right colon and gallbladder originating from an invasive lobular carcinoma is described. Conclusion: Adequate diagnostic procedures should be performed in patients with a history of breast cancer and who show gastrointestinal symptoms to rule out the potential presence of gastrointestinal metastases.
