Abstract

Fibroadenoma is one of the most common breast lesion. It can usually be found in the upper outer quadrants where most breast parenchyma is located. The location of fibroadenomas involving the accessory breast is, however, uncommon. There are clinical significance in accessory breast tissues being affected by the same diseases and alterations that compromise a typical breast tissue. The diagnostic (mammography, ultrasonography, cytology and biopsy) and therapeutic protocol for an accessory breast tissue is prudent in detecting early malignancies. We report a case of fibroadenoma found in accessory breasts.
