A 74-year-old man complained of blood in his urine over a 1-week period beginning in early October 2013, and was examined in the urology department of our hospital. A thorough examination revealed bladder cancer, and surgery was planned after two cycles of preoperative gemcitabine plus cisplatin chemotherapy. A chest computed tomography (CT) performed to evaluate the response to chemotherapy revealed a mass in the right breast. The patient had previously complained about the same site, and mammography and ultrasonography had suggested the possibility of a malignant mammary gland tumor. The results of aspiration cytology were Class V, and based on that finding, a diagnosis of cancer of the right breast was made. In February 2014, we performed a mastectomy, while preserving the pectoral muscles, along with sentinel node biopsy, total cystectomy, urethrectomy, pelvic lymph node dissection, and ureteroileal anastomosis. The histopathological diagnosis of the right breast tumor was invasive ductal carcinoma [scirrhous carcinoma, ly (+), v (-), g (+), f (+),5 (+), nuclear grade 1 = atypia 2+mitosis 1, EIC (-), ICT (-), NCAT (-)]. A micrometastatic tumor measuring approximately 1 mm was observed in the sentinel lymph node. The breast disease was classified as pT1N1 mi (sn) MO, Stage IIA, and thetumorwasER (+), PgR (+), HER2/neu (2 +), and FISH (-). The bladder cancer was diagnosed as urothelial carcinoma, non-papillary, invasive G2>G3, pT2a; no pelvic lymph node metastases were detected, and it was classified as pT2aN0M0, Stage II. Synchronous male breast cancer and bladder cancer is a very rare condition, and we report the case with a review of the literature.
