Recurrent ectopic primary breast adenocarcinoma of the vulva with a 19-year follow-up period

Abstract

We present a case of an ectopic breast adenocarcinoma of the vulva with metastatic local recurrence and a total follow-up period of 19 years, the longest documented in the literature to our knowledge. Following surgical excision, radiation therapy and hormonal treatment after the recurrence, the patient has remained disease free. This case demonstrates the potential for malignant transformation in accessory breast tissue and highlights the importance of close surveillance and regular physical examinations in patients with a history of ectopic breast malignancy.
