Fibroepithelial lesion of the breast (FEL) can pose a diagnostic challenge with a core needle biopsy (CNB) because cellular fibroadenoma is difficult to distinguish from phyllodes tumor (PT). In this 10-year single-institution experience with FEL (https://doi.org/10.1245/s10434021-10931-0), age, size of tumor, mitotic activity, and stromal overgrowth on the CNB were predictive of PT after excision, and FEL on CNB was upstaged to PT in 25.8 % of the resected cases. To rule out phyllodes tumor, FEL on CNB warrants excision.
