Giant fibroadenoma of the breast mimicking phyllodes tumor in an adult female: emphasizing the role of cytology in the diagnosis

Abstract

Giant fibroadenoma is an uncommon variant of fibroadenoma with an overall incidence of <4%. It is common in adolescent age group and is seldom seen in elderly. Often surgeons might encounter a diagnostic dilemma between phyllodes tumor (PT) of the breast and a giant fibroadenoma. We herein report a similar case of a middle-aged woman with an unusually large fibroadenoma of the breast mimicking a PT and emphasize the role of fine-needle aspiration cytology in differentiation of these two different breast entity.
