Case Report - Metastatic breast disease causing ureteric obstruction and haematuria

We report a 96-year old lady who had previously undergone simple right mastectomy for a grade 3 infiltrating duct carcinoma presenting with painless haematuria. Imaging studies revealed right sided hydronephrosis with a lower ureteric mass invading the bladder mass. Cystoscopic examination confirmed a solid lesion on the left side of the trigone, which was resected. The histology was consistent with metastatic infiltrating carcinoma of the breast. This case is reported to highlight the rarity of the breast carcinoma metastasizing to the bladder.
