Unusual Metastasis From Breast Cancer: Case Report.

Metastatic breast cancer among young women represents a serious public health issue. The most frequent sites of dissemination are bone, liver, lung, lymph nodes and brain. Bladder location is extremely unusual. We present the case of a 33-year-old female who was receiving palliative chemotherapy for bilateral metastatic invasive lobular cancer. Following episodes of macroscopic hematuria, a CT scan was performed, which revealed a thickening of the bladder wall. After an endoscopic resection with immunohistological analysis, the diagnosis was confirmed. Voiding symptoms in a woman with a history of breast cancer should be evaluated to rule out a secondary urinary tract lesion. As soon as the diagnosis is determined, appropriate therapy should be initiated.
