　　【摘要】副乳又称多乳畸形,是胚胎原始乳腺始基发育而成。其发生率为1%-6%,男女皆可发生,女性多于男性,是具有遗传性,副乳多发于腋前线处,可同时具有乳头,乳晕,乳腺,亦可仅具其一,副乳可以发生癌变,但前提是必须具有乳腺腺体组织,具有腺体组织的副乳也是一种受性激素影响的性器官,任何引起乳癌的因素都可以引发副乳的癌变,副乳癌常见的临床是在发生副乳的部位出现体表肿块,发病前多无明显症状,故就诊时多偏晚,而且由于副乳好发于淋巴组织丰富的腋区及腹股沟区,癌组织的扩散和转移比较早,使本病发现时已处于Ⅱ期或Ⅳ期预后较差。

　　【Abstract】The vice-breast the Chindu breast is also abnormal, is the embryo primitive mammary gland original basis growth becomes. Its formation rate is 1%-6%, the men and women all may occur, the female is more than the male, has the heredity, the vice-breast sends in the armpit front place, may simultaneously have the nipple, the areola, the mammary gland, may also only have its one, the vice-breast may have the cancer, but the premise is must have the mammary gland gland organization, has the vice-breast which the gland organizes is also one kind the sex hormone influence reproductive organ, any causes the breast cancer factor to be possible to initiate the vice-breast’s cancer, vice-breast cancer common clinical is in has the vice-breast’s spot to present the body surface tumour, before the morbidity, many not obvious symptoms, when receives a medical examination many late, moreover as a result ofThe breast good sends in the Lymphatic tissue rich armpit area and the regio inguinalis, the proliferation which and the shift the cancer organizes is quite early, causes time this sickness discovery has been inⅡTime orⅣThe time prognosis is bad.

　　副乳腺癌是指发生于副乳腺的肿瘤,是乳腺癌的一种特殊类型,发生率很低。
　　1临床资料
　　女50岁,为腋下前线处肿物,肿物于皮肤无粘连,肿块1*0.6cm,病理诊断浸润性导管癌同侧腋窝淋巴结转移。
　　2讨论
　　副乳又称多乳畸形,是胚胎原始乳腺始基发育而成。其发生率为1%-6%,男女皆可发生,女性多于男性,是具有遗传性,副乳多发于腋前线处,可同时具有乳头,乳晕,乳腺,亦可仅具其一,副乳可以发生癌变,但前提是必须具有乳腺腺体组织,具有腺体组织的副乳也是一种受性激素影响的性器官,任何引起乳癌的因素都可以引发副乳的癌变,副乳癌常见的临床是在发生副乳的部位出现体表肿块,发病前多无明显症状,故就诊时多偏晚,而且由于副乳好发于淋巴组织丰富的腋区及腹股沟区,癌组织的扩散和转移比较早,使本病发现时已处于Ⅱ期或Ⅳ期预后较差。
　　副乳癌的诊断应注意与以下情况相鉴别:(1)同侧乳房腋尾部癌;(2)乳腺癌的淋巴结转移癌;(3)皮肤附件来源肿瘤。除详细了解病史及进行细致的临床检查外,应结合乳房激光扫描,B超检查以及穿刺细胞检查,术后病理检查。
　　诊断副乳腺癌时必须应看:(1)腑区,锁骨下区癌,临床与组织学检查必须查到与正常部位乳腺无关的副乳腺组织亦可诊断为副乳腺癌;(2)腋区肿块组织学检查为癌时,必须在癌组织的周围见到腺小叶结构或管内癌图像而不是淋巴组织结构时,方可排除腋淋巴结转移癌;(3)正常部位乳腺无癌,或伴发有组织学类型不同的癌,发现愈早预后愈好。
