Metachronous bilateral ectopic breast carcinoma: a case report

Anna Fachinetti et al. Gland Surg. 2018 Apr.

Abstract

An incomplete regression of the mammary line during embryogenesis occurs in 0.2-6% of the population, which may result in the presence of ectopic breast tissue (EBT). The development of a carcinoma in the EBT is a rare event. The authors present a case report of a 76-year-old female patient, with a lobular carcinoma in an abdominal wall EBT submitted to surgery and adjuvant chemotherapy.

Keywords: Breast cancer; ectopic breast cancer; lobular breast carcinoma; milk line.
