摘要

The gallbladder is an uncommon location for tumor metastases. Breast cancer seldom spreads to the gallbladder, although melanoma and renal cell tumors typically do. We report a case of a 58-year-old woman with chronic cholecystitis caused by gallstones. Following a laparoscopic cholecystectomy, a nodule was discovered on the gallbladder wall. Based on her medical history and pathological tissue molecular typing, the diagnosis was determined to be gallbladder metastasis of invasive breast ductal carcinoma, with a negative hormone receptor. Two years prior, the patient had undergone a modified radical mastectomy for left breast cancer. The postoperative pathology revealed grade III invasive ductal carcinoma, pT2N1M0, and a negative hormone receptor. This case report highlights the rare occurrence of invasive breast ductal carcinoma metastasizing to the gallbladder.
