Abstract

Accessory breast tissue is a developmental anomaly defined as persistence of breast tissue along the embryonic mammary line in the mid-thoracic region. Rarely, an abnormally located remnant of the line persists and develops into completely formed mammary glands. A 61-year-old woman presented with a pedunculated mass on the mid-lower abdomen, below the umbilicus. She detected a pea-sized nodule a few decades ago and it gradually enlarged since 1 year ago. There was no pigmented prominence resembling a nipple. Histological finding revealed lobules of the breast forming islands of glandular tissue. We believe this is an unusual case of accessory breast tissue mimicking soft fibroma as a pedunculated mass.
