Urinary bladder metastases from breast carcinoma : review of the literature starting from a clinical case

Bladder metastases from solid tumors are rare. Breast carcinoma cells seldom spread to the urinary bladder. We report the case of a patient with invasive breast carcinoma who developed a breast recurrence followed by bone and urinary bladder metastases. Starting from this clinical case we review the available literature on this issue. Only few cases of urinary bladder metastases from primary breast cancer have been reported, although the case reports have increased in recent years. Patients with breast cancer presenting with urinary symptoms should be examined for possible bladder metastases
