Breast cancer with gastric metastasis in invasive lobular carcinoma: a case report and literature review.

ABSTRACT: Breast cancer is one of the most common malignant tumors in women. Most early-stage breast cancer does not have the typical symptoms and signs. The common metastatic sites of breast cancer are bones, lymph nodes, soft tissues, lungs, brain, liver. Cases with the gastrointestinal (GI) tract as the first site of metastasis are relatively rare. Their clinical, imaging, and gastroscopic manifestations lack specificity, making them difficult to distinguish from primary gastric cancer. A 45-year-old woman presented with a week-long history of black stools, later diagnosed as gastric metastasis from breast cancer. The patient had undergone surgery, radiotherapy, and chemotherapy 18 years prior for left invasive lobular carcinoma (ILC) of the breast. Current symptoms included black stools, hiccups
