Abstract
This is a case of a previously healthy 29-year-old female with erythema and skin excoriations of the left breast nipple-areolar complex (NAC). After a repeat trial and failure of topical hydrocortisone, a diagnostic mammogram and nipple biopsy revealed Paget's disease (PD) of the nipple with ductal carcinoma in situ (DCIS). A subsequent genetic analysis found a breast cancer 2 (BRCA2) gene mutation. Treatment consisted of a left breast skin-sparing simple mastectomy with sentinel lymph node (SLN) biopsy and immediate tissue expander placement for implant reconstruction. Further management involved right breast short-interval surveillance with annual mammography and magnetic resonance imaging (MRI) with the possibility of prophylactic surgery along with oophorectomy after childbearing.
