ACCESSORY BREAST TISSUE IN THE AXILLA IN A PUERPERAL WOMAN- CASE STUDY

Abstract

Ectopic or accessory breast tissue (EBT) is an uncommon residual tissue that persists from normal embryonic development, found in 2-6% of the female population. EBT may occur anywhere along the embryonic mammary streak, but is most commonly located in the axillary region. EBT can consist of any or all components of the breast and may be functional or non-functional. The development of this tissue is hormone- dependent, similar to normal breast tissue. EBT presents as asymptomatic mass and may prove to be a diagnostic challenge in the absence of areola and nipple. The identification and distinction of EBT from other breast pathologies occurring in the area, both benign and malignant, is essential for proper management. In most of the cases, these lesions are asymptomatic and do not warrant any intervention unless they produce discomfort. In this report, we present a case of an ectopic breast tissue in the left axilla of an 24-year-old Asian Indian primipara patient. The importance of FNAC as diagnostic tool in suspected cases of polymastia without nipple/areola and the conservative approach through regular follow-up for management of proven benign ectopic breast tissue are highlighted.
