Synchronous bilateral breast cancer is extremely rare in men and has not, up to date, been reported in Korea. A 54-year-old man presented with a palpable mass in the right breast. The right nipple was retracted and bilateral axillary accessory breasts and nipples were present. On physical examination, a 2 cm-sized mass was palpated directly under the right nipple, and, with squeezing, bloody discharge developed in a single duct of the left nipple. There was no palpable mass in the left breast, and axillary lymph nodes were not palpable. Physical examination of external genitalia revealed a unilateral undescended testis on the left side. Synchronous bilateral breast cancer was diagnosed using mammography, ultrasonography, and core-needle biopsy. Histopathological examination revealed invasive ductal carcinoma in the right breast and ductal carcinoma in situ in the left breast. Bilateral total mastectomy, sentinel lymph node biopsy, and excision of accessory breasts in the axilla were performed.
男性双侧同步性乳腺癌极为罕见，在韩国尚未有相关报道。一名 54 岁男性因右侧乳腺可触及肿块就诊。右侧乳头内陷，双侧腋窝副乳腺及乳头存在。体格检查发现，右侧乳头下可触及 2cm 大小的肿块，挤压时左侧乳头单一乳管有血性溢液。左侧乳腺未触及肿块，腋窝淋巴结未触及。外生殖器检查发现左侧单侧隐睾。通过乳腺 X 线摄影、超声和核心针活检诊断为双侧同步性乳腺癌。组织病理学检查显示右侧乳腺浸润性导管癌，左侧乳腺导管原位癌。行双侧全乳切除术、前哨淋巴结活检术和腋窝副乳腺切除术。
