Description of a case, bladder metastasis from breast carcinoma

Breast cancer is the main cause of cancer-related death in women and almost all related deaths occur due to metastasis. The most frequent places of metastasis are lymph nodes, bone, lung, liver, and central nervous system. Bladder metastasis are very rare, being described in only 7% of autopsy studies. Besides being uncommon, most cases of secondary bladder involvement occur as a result of disseminated disease, being the solitary bladder metastasis sporadically reported.

This article presents the case of a woman with a history of invasive lobular breast carcinoma who, 18 months after diagnosis, presents herself with complaints of urinary urgency and urinary incontinence. The requested complementary exams revealed a voluminous bladder mass and the anatomopathological study was compatible with a metastatic lesion.
