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.
