Late urinary bladder metastasis from breast cancer

INTRODUCTION: Breast cancer (BrC) is the most common non-dermatologic cancer in women. It frequently metastasizes to lung, liver and bone, while the urinary bladder is considered as an unusual site for BrC metastases. MATERIALS AND METHODS: Four years after her first oncologic surgical approach, a known BrC patient complained of a left flank pain, dysuria and urgency. Computed tomography (CT scan) imaging showed an irregular thickening of the left bladder wall and bilateral hydronephrosis. RESULTS: A bladder metastases from BrC was diagnosed based on a histological examination of a transurethral resection of the bladder (TURB-T) specimen. CONCLUSIONS: In patients with a history of BrC, urinary bladder screening is not needful. However, if low urinary symptoms persist, an evaluation of the bladder should be considered to rule out metastatic involvement.
