The male breast cancer is very less common as compared with the female breast cancer. We report a case of 64-year-old man who presented with the history of lower urinary tract symptoms. The digital rectal examination revealed hard and nodular prostate, and serum prostate-specific antigen level was 23.4 ng/mL. Ga-labeled prostate-specific membrane antigen PET/CT revealed prostate-specific membrane antigen-expressing lesions in the prostate, axillary tail of the right breast, and axillary lymph nodes. Histology from prostate revealed prostate carcinoma, whereas fine-needle aspiration from the breast revealed invasive ductal carcinoma of the breast.
男性乳腺癌比女性乳腺癌少见得多。我们报告了一例 64 岁男性患者，他因下尿路症状就诊。直肠指检发现前列腺坚硬且呈结节状，血清前列腺特异性抗原水平为 23.4ng/mL。Ga 标记的前列腺特异性膜抗原 PET/CT 显示前列腺、右侧乳腺腋尾和腋窝淋巴结存在前列腺特异性膜抗原表达的病灶。前列腺组织学显示前列腺癌，而乳腺细针抽吸活检显示乳腺浸润性导管癌。
