Unusual pattern of breast carcinoma metastasis to the urinary bladder: Case report and review of literature

Breast cancer has the greatest prevalence among females worldwide and most common leading cause for mortality overall. It usually metastasizes to lung, liver, lymph nodes, bones, and skin but rarely spread to other sites, such as urinary bladder and retroperitoneum. Survival of metastatic breast carcinoma to the bladder is poor as compared with metastasis to other organs (liver, lung, and lymph nodes). We present here what we believe is the first rare case in Saudi Arabia of breast carcinoma metastasis to the urinary bladder in a 58-year-old female.
