A Rare Case of Fibroadenoma in an Accessory Breast over Anterior Chest Wall

Abstract

Accessory breast tissue is an uncommon condition which occurs in 0.4–6% of women. It is mostly located in the axilla where it can cause diagnostic difficulty, especially if it is unilateral and large. Usually it is bilateral and presents as an asymptomatic mass during pregnancy or lactation. The diagnosis of ectopic breast tissue is important as it can undergo the same pathological changes that occur in a normal breast, such as mastitis, fibrocystic disease and carcinoma. We present a case of unilateral accessory breast without nipple and areola over anterior chest wall with a fibroadenoma inside it in a 20 year old lady.
