The stomach is an infrequent site of breast cancer metastasis. It may prove very difficult to distinguish a breast cancer metastasis to the stomach from a primary gastric cancer on the basis of clinical, endoscopic, radiological and histological features. We present a case of a 57-year-old woman of gastric metastasis from breast cancer by immunohistochemistry 6 years after mastectomy. Since no other lesions were observed in the image examination, she underwent laparoscopic gastrectomy and endocrine therapy. The patient remains well after 6 years from gastrectomy. Complete histopathological and immunohistochemical analysis of the gastric biopsies and comparison with the original breast cancer pathology is important
