Introduction:
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.
Materials And 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.
Conclusion:
Larger mass size and increased histologic cellularity were associated with excision recommendation, but only clinical growth was associated with PT.
