Male breast cancer is rare, accounting for approximately 1% of breast cancers. Metastasis from extra-mammary malignancy to the breast in men is extremely rare. The most common primary tumors that metastasize to the breast in male are prostate, lung, stomach, colorectal cancer, melanoma, and sarcoma. To our knowledge, only a few cases of bladder cancer presenting with metastasis to the male breast have been reported, and metastasis with infiltration rather than mass is extremely rare. We report imaging findings on mammography and ultrasonography in a 59-year-old male with bladder cancer metastatic to the breast.
男性乳腺癌较为罕见，约占乳腺癌的1%。男性乳腺外恶性肿瘤转移至乳腺极为罕见。转移至男性乳腺的最常见原发肿瘤是前列腺癌、肺癌、胃癌、结直肠癌、黑色素瘤和肉瘤。据我们所知，仅有少数膀胱癌转移至男性乳腺的病例报道，且以浸润而非肿块形式转移极为罕见。我们报告了一名59岁男性膀胱癌转移至乳腺的乳腺X线摄影和超声检查的影像学表现。
