Breast cancer in male is rare, accounting for 1%of all breast cancers.Among male breast cancers, noninvasive carcinoma is extremely rare.We experienced a case of noninvasive carcinoma of the breast in a male.A 72-year-old male was referred to our hospital with a chief complaint of the tumor and blood secretion from the left nipple.Mammography revealed a highdensity mass.Ultrasound examination revealed low echoic mass at the E area, and it measured 1.5 cm.Core needle biopsy failed to provide a definitive diagnosis, and we performed an excisional biopsy of the tumor.The pathological diagnosis was noninvasive ductal carcinoma.He underwent a mastectomy without sentinel lymph node biopsy because the resection margin was positive.The patient received no adjuvant therapy and the patient's postoperative course was uneventful for 1 year.As there have been few reports on male noninvasive ductal carcinoma, we do not have evidence for indication of the sentinel lymph nodes and postoperative adjuvant therapy such as tamoxifen.We may confuse the treatment policy.
男性乳腺癌较为罕见，占所有乳腺癌的1%。在男性乳腺癌中，非浸润性癌极为罕见。我们诊治了1例男性乳腺非浸润性癌患者。一名72岁男性因左侧乳头肿物及血性分泌物为主诉就诊于我院。乳腺钼靶检查显示高密度肿块。超声检查发现E区低回声肿块，大小为1.5 cm。粗针穿刺活检未能明确诊断，遂对肿瘤进行了切除活检。病理诊断为非浸润性导管癌。由于切除切缘阳性，患者未行前哨淋巴结活检即接受了乳房切除术。患者未接受辅助治疗，术后1年病情平稳。由于关于男性非浸润性导管癌的报道较少，我们尚无证据表明前哨淋巴结及他莫昔芬等术后辅助治疗的指征。我们可能会混淆治疗策略。
