Fibroadenomas are benign tumors that commonly occur in the early reproductive age group. They are hyperplastic, benign fibroepithelial lesions of the breast composed of both stromal and epithelial components. They arise from the terminal ductal and lobular units. Since they originate from the terminal ductal lobular units with the surrounding stroma, they can have the entire spectrum of benign proliferative changes. Fibroadenomas exhibiting these benign proliferative changes are classified as complex fibroadenomas.
