Inguinal Sentinel Lymph Node in a Patient With Recurrent Breast Cancer

Sentinel lymph node biopsy is the standard of care for axillary staging in early, clinically node-negative breast cancer. The lymphatic pathways could be altered after receiving axillary treatments such as radiation and/or axillary lymph node dissection. We report a case of inguinal and contralateral axilla SLNs in breast cancer recurrence.
