Contralateral Axillary Lymph Node Metastases Detected by Repeat Sentinel Lymph Node Biopsy in a Patient with Ipsilateral Breast Tumor Recurrence: A Case Report

Year: 2026

Type: article

Abstract: INTRODUCTION: There is no consensus on the significance of repeat sentinel lymph node (SLN) biopsy in a patient with ipsilateral breast tumor recurrence (IBTR). CASE PRESENTATION: at the age of 35. Because of the contralateral SLNs identified on radioisotope lymphoscintigraphy, we decided to perform a left mastectomy with contralateral axillary lymph node dissection. Intraoperative SLN mapping using indigo carmine was negative. A total of 3 contralateral axillary lymph node metastases, all sentinel nodes, were identified among 18 resected nodes. Because this patient's second BC was an invasive ductal carcinoma, a different histology from her first tumor, we diagnosed a new primary BC along with contralateral axillary lymph node metastases and planned adjuvant therapy accordingly. CONCLUSIONS: Repeat SLN biopsy for IBTR plays a key role in determining accurate SLN status and in optimizing adjuvant therapy.
