Description

<p>Metastasis of breast cancer to the bile ducts is extremely rare. A 67-year-old woman underwent a total mastectomy with axillary lymph node dissection for left breast cancer (pT1c N2 M0), 19 years prior to presentation and received adjuvant chemotherapy and endocrine therapy for 5 years. However, chemotherapy was re-administered until recently for recurrent lymph node and bone metastases. The patient presented with liver dysfunction and jaundice. Radiological evaluation revealed a mass in the upper common bile duct. We performed left liver lobectomy and extraductal cholecystectomy to establish a definitive diagnosis and treat jaundice. Histopathological examination of the resected specimen revealed adenocarcinoma showing features similar to those of breast cancer. The aforementioned operation led to accurate diagnosis, and the patient was administered appropriate palliative treatment.</p>
