Breast Cancer Metastasis with a Ureteral Obstruction and Bladder Mass.

Breast cancer is the most common cause of cancer mortality in females globally, and a significant proportion of patients develop metastatic disease. Common metastatic sites of breast cancer include bone, lung, liver, and brain. Secondary neoplasms (metastases from other primary sites) represent a minority of all malignant bladder tumors In this report, we describe a case of breast cancer metastasis with ureteral obstruction and bladder mass in a 60-year-old African-American female. For over a decade, this patient was asymptomatic and had been under surveillance following bilateral radical mastectomy for invasive ductal carcinoma (IDC) with adjuvant chemoradiotherapy. Unrelated imaging revealed an incidental finding of right hydronephrosis. Subsequent cystoscopy revealed a bladder mass obstructing the right ureteral orifice. Transurethral resection of a bladder tumor and ureteral stent placement were performed, and the pathology findings favored metastatic breast cancer. The details of the case are intended to help further knowledge of urinary bladder metastases. This case is unusual in that the patient was asymptomatic, her breast cancer type is associated with a lower incidence of bladder metastases, and the bladder was the solitary location of metastasis.
