[Sentinel node technique in local relapse after breast-conserving surgery].

Mastectomy is the treatment of choice in local relapse after breast-conserving surgery. We present two cases where the sentinel node technique was used. The first case presents with one negative SN after axillary dissection 11 years earlier. The second case presents with a new SN with micrometastases and axillary dissection with 11 negative nodes 2 years after a negative SN procedure. We recommend the use of the sentinel node technique in surgery for relapse in order to optimize the staging.
