Late urinary bladder metastasis from breast cancer.

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.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.A bladder metastases from BrC was diagnosed based on a histological examination of a transurethral resection of the bladder (TURB-T) specimen.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.
