Metastatic breast cancer to the contralateral axilla (CAM) is defined as stage IV disease. We postulate that CAM represents an extension of local-regional disease rather than distant metastasis and may have a better outcome. A single-institution, retrospective review of breast cancer cases from January 2005 and May 2011 was performed to identify cases with CAM. ⋯ Three pts have no evidence of disease at a mean follow up of 5.8 years (range 1.5-8.2). CAM may have different prognostic implications than other distant metastases and may occur through dermal lymphatic spread. Further study is warranted on the prognosis and management of these challenging and rare cases.
