An unusual location for metastasis - Breast cancer in the bladder.

Metastatic breast cancer is the second most common cancer related death amongst women in the United States. The common locations for metastases-lymph nodes, bone, lung, liver, brain - are well reported. Rarely, breast cancer metastasizes to the bladder. We present a case of primary hormone positive, HER2 unamplified breast cancer, thirteen years in remission, with triple negative metastases to the bladder. Urologists should consider breast metastases in patients with even a remote history of breast cancer who present with gross hematuria to avoid delays in treatment.
