Nipple discharge after nipple-sparing mastectomy: should the areola complex always be removed?

Nipple discharge (ND) is a common symptom with a reported incidence of 2% to 5% of patients referred to breast cancer clinics. Approximately 90% of ND is of benign etiology. An underlying carcinoma is present with a rate of 6% to 21%. This is more frequent if it is associated with clinical or radiologic abnormality. ND after nipple-sparing mastectomy (NSM) is a rare event as the whole retroareolar glandular tissue is usually completely removed with mastectomy. ND is otherwise possible if a small amount of tissue is accidentally left by the surgeon or with the aim of reducing the risk of the nipple-areola complex (NAC) necrosis. This condition can be of concern as it may imply a local recurrence and therefore implicate NAC removal. Herein we report a case of a ND in an NSM in which only a selective duct excision allowed NAC preservation.
