Abstract

Ectopic breast tissue is rare and typically presents as an axillary mass. Previous reports have identified ectopic breast tissue in the vulva, but malignancy is exceedingly uncommon. We present a 62 years old with locally advanced breast carcinoma arising in the vulva demonstrates the utilization of sentinel lymph node mapping to identify metastatic lymph nodes previously unable to be identified via traditional surgical exploration. Our case supports the principles of adjuvant therapy for breast cancer to be applied to ectopic breast cancer arising in the vulva. A literature review highlights common key points in similar cases to guide management.

Keywords: Vulvar cancer, Ectopic breast, Sentinel lymph node, Breast cancer, Vulvar breast cancer

Core tip: Our findings describe the presentation of ectopic breast cancer in the vulva. We demonstrate use of sentinel lymph node technology with identification of the sentinel node, only possible after the use of this technology. We conclude with a review of the literature outlining treatment of this enigmatic disease.
