Breast phyllodes tumors are uncommon fibroepithelial neoplasms with a range of histologic features. Surgical excision is the primary management, but the need for excision to negative margins in benign and borderline phyllodes tumors is unclear. Here, we review the surgical management patterns and outcomes of 90 patients with benign and low-grade fibroepithelial lesions of the breast treated at our institution, including 19 borderline phyllodes tumors, 52 benign phyllodes tumors, and 19 representative neoplasms with overlapping features of fibroadenoma and benign phyllodes tumors, which were classified as 'fibroadenomas with phyllodal features'. In total, 52 (58%) had positive surgical margins on first excision, and of these 17 (33%) underwent re-excision to achieve negative margins. Residual tumor was identified in three (18%) re-excisions. Patients with fibroadenoma with phyllodal features were more likely to have a positive surgical margin than with benign phyllodes tumors or borderline phyllodes tumors (89 vs 49%, P=0.0015), and were less likely to undergo re-excision for positive margins (12 vs 43%, P=0.031). In total, there were three recurrences (3%), with one per fibroadenoma with phyllodal features, benign phyllodes tumor, and borderline phyllodes tumor. There was no statistically significant difference in recurrence rates between patients with positive or negative margins, or between patients with positive margin with or without re-excision. The extent of the positive margin did not predict recurrence. In conclusion, the recurrence rate of benign and low-grade fibroepithelial lesions is low and not associated with the original margin status. Patients with fibroadenomas with phyllodal features, benign phyllodes tumors, or selected borderline phyllodes tumors and positive margins on initial excision may be managed conservatively, with close follow-up and timely re-excision of any potential recurrence.
