Background: Breast cancer is rare in men and there is no report of male breast cancer (MBC) with ureteral metastasis. In this study, we report the first case of MBC with ureteral metastasis. Case presentation: A 60-year-old man was diagnosed with triple negative breast cancer (TNBC) with lymph nodes metastasis. After surgery, chemotherapy and radiotherapy he was diagnosed with ureter metastasis because of hematuria. This patient took a Precitype gene test (immune index and PAM50) after several lines of treatment and the result indicated that this was a Luminal A subtype case, which was quite different from his immunohistochemical staining. We adjusted his therapeutic regimen according to the genetic test but there was no obvious efficacy and he passed away five months later. Conclusions: MBC patients with urinary symptoms should be considered for the possibility of metastasis although urinary metastasis in breast cancer is rare. We still need more research and evidence of treatment recommendations for MBC.

Case presentation: A 60-year-old man was diagnosed with breast cancer and lymph nodes metastasis. After surgery, chemotherapy and radiotherapy he was diagnosed with left arm metastasis. Then he received mass dissection and chemotherapy again. He was diagnosed with ureter metastasis because of hematuria. This patient took a Precitype gene test (immune index and PAM50) after several lines of treatment and the result indicated that this was a Luminal A subtype case, which was quite different from his immunohistochemical subtype. We adjusted his therapeutic regimen according to the genetic test but there was no obvious efficacy and he passed away five months later.

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
