Core Tip
Core Tip: Breast cancer, the most frequently diagnosed type of cancer worldwide, is the leading cause of death due to malignant disease in women. We present the case of a female patient, 73 years of age, who sought care due to weakness, mild abdominal pain, arthralgia, and weight loss. She was taking anastrazole as a maintenance therapy for a localized breast cancer. She presented with moderate anemia and elevated acute phase markers. Upper digestive endoscopy showed isolated erosion in the gastric corpus. In anatomopathological study, the lesion was found to be compatible with signet-ring cell adenocarcinoma, while in in immunohistochemistry it was confirmed to be a metastasis of breast carcinoma, being positive for estrogen antibody. Further imaging studies determined numerous proximal bone metastases. The patient has been treated and followed up for 6 mo, and her anemia, arthralgias and acute phase markers have normalized. Systemic treatment strategies appear to be the best choice for gastric metastasis from breast cancer, providing disease control and relapse-free survival. Prospective studies with longer follow up are needed to better understand the biological, pathological, and clinicopathological characteristics and outcomes of the endoscopic features associated with metastatic gastric cancer from breast carcinoma.
