Cellular fibroadenoma on Core needle biopsy: management recommendations for the radiologist.
BACKGROUND
Cellular fibroadenomas (CFA) are difficult to distinguish from phyllodes tumor (PT) at biopsy. This study's purpose was to determine what CFA characteristics were associated with recommendations to follow-up or excise and if the current algorithm was correct.


METHODS
Databases from 2002 to 2014 were reviewed. Mass characteristics and post biopsy recommendations were recorded.


RESULTS
81 CFAs were diagnosed; 19 cellular and 62 with slightly cellular stroma. 21 masses were surgically excised with 2 PTs diagnosed.


CONCLUSIONS
Larger mass size and increased histologic cellularity were associated with excision recommendation, but only clinical growth was associated with PT.
