The objective of this study was to consider the clinicopathological features of phyllodes tumors that underwent surgery in our hospital. </div> <div style="text-align:justify;"> <b>Material and Methods: </b> We retrospectively analyzed the medical records of 16 patients who had histologically diagnosed phyllodes tumors over 9 years. </div> <div style="text-align:justify;"> <b>Results: </b> There were 16 female patients with a mean age of 45.6±15.3 years. Magnetic resonance imaging was performed in 5 cases for preoperative diagnosis, and 4 were reported as phyllodes tumors, all of these patients were having high-grade phyllodes tumors (borderline or malignant) histopathologically. Preoperative core biopsy was performed in 14 patients, and histopathologically phyllodes tumor was diagnosed in two patients. In six patients, differentiation between hypercellular fibroadenoma and phyllodes tumor could not be performed. Breast-conserving surgery was the most common type of operation performed in 10 (62.5%) patients, three patients with positive margins were underwent reoperation. The pathological diagnoses were benign, borderline, and malignant in seven (43.8%), five (31.3%) and four (25.0%) patients, respectively. The median diameter of the tumors was measured as 6 cm after the postoperative pathological analysis. The median follow-up time was 36 months. During this time, there was no local or systemic recurrence. </div> <div style="text-align:justify;"> <b>Conclusion: </b> Wide excision with a clear margin appears to be the most important factor in the management of these tumors and in the prevention of local recurrence. The preoperative diagnosis of phyllodes tumors contributes to decreasing the necessity for secondary surgical intervention avoiding border positivity. </div>}, number={2}, publisher={Duzce University}
