乳头作为人体乳房腺体与外界连接的通道,其解剖结构和功能正常是保证乳汁顺利排出的基本条件。目前国内外对乳头的研究,主要集中在基于乳头乳晕复合体表面细胞成分的肿瘤筛查、保乳手术时乳头乳晕复合体周围神经分析、经乳头内乳导管灌注铸型、乳头勃起机制和乳头内陷的治疗等,绝大多数是根据乳头周围血管神经解剖或细胞生物学进行研究,而对乳头内部的微观解剖分析较少~([1-4])。常规的乳头病理切片可以发现乳头内部存在血管、神经、乳
Nipple as the human breast gland and the outside world to connect the channel, the anatomical structure and function is normal to ensure the smooth discharge of milk basic conditions. At present, the studies on the nipples at home and abroad mainly focus on the tumor screening based on the cell components of the surface of the nipple areola complex, the peripheral nerve analysis of the nipple areola complex during the breast-conserving surgery, the intraductal milk infusion catheter, the nipple erection mechanism and the nipple The treatment of invagination, etc., are mostly based on the anatomy or cell biology of the vessels around the nipple, while the micro-anatomic analysis of the nipple is less ~ ([1-4]). Conventional papillary pathology can be found inside the nipple blood vessels, nerves, milk
