title: Accessory nipple reconstruction following a central quadrantectomy: a case report.
abstract: BACKGROUND
  nipple dichotomy (or intra-areolar polythelia) is a rare congenital malformation in which one or more supernumerary nipples are located within the same areola.A case of a woman undergoing a central quadrantectomy with a contralateral supernumerary nipple used for reconstruction is reported. No other report in the Literature, according to our search, has focused on reconstructive use of an accessory nipple after breast conserving surgery.
  
  
  METHODS
  the patient is a 73 year-old Caucasian woman, who two years earlier underwent a lower-outer left Quadrantectomy plus axillary sampling and radiation therapy for a 2,2 cm lobular carcinoma with no lymph node involvement.A routine follow-up assessment showed an important fibrotic change on the operated breast, just across the infra-mammary fold; at a breast Magnetic Resonance Imaging, a 1,5 cm area in retroareolar position, suspicious for local recurrence, was evident.An open biopsy was therefore performed, under local anaesthesia, including the nipple-areolar complex to realize a central Quadrantectomy with a Grisotti procedure; a congenital dichotomic nipple in the contralateral breast was then used to repair the defect through a "nipple-sharing" technique. The final histological examination reported a fibrotic mastopathy without atypias.
  
  
  CONCLUSIONS
  in this case, the "nipple-sharing" technique has allowed in the same time the correction of a rare congenital defect and provided the surgeon with a supernumerary nipple to be used in the immediate reconstruction after breast conserving surgery.
