RESUMEN
Breast cancer is usually associated with metastases to lungs, bones and liver. Breast carcinoma metastasizing to the gallbladder is very rare. We report the case of 45-year-old female with clinical presentation of acute Cholecystitis, who underwent cholecystectomy in emergency. The Gallbladder showed a nodule on the Gallbladder wall. Histological examination disclosed a metastasis from a lobular breast carcinoma with positive hormone receptors. The patient had received three months previously a right mastectomy with axillar dissection followed by chemotherapy and radiotherapyfor lobular breast cancer stage III, PT3N1M0, showing hormone receptors. We present a rare case of acute cholecystitis from metastatic breast cancer three months after management of primary cancer.
