Objective: We aimed to investigate the epidemiological and characteristic features of patients treated for breast masses in our clinic and share our experiences.

Material and Methods: Patient records were reviewed retrospectively. Demographic and clinical data were investigated. The patients were divided into those who were operated on at the first admission (group 1) and those who were operated on after the follow-up (group 2) and compared. The statistical analysis evaluated with SPSS version 21. p<0.05 was considered significant.

Results: Forty-eight patients who were operated on for breast mass in 10 years were included in the study. There was no difference between the groups regarding mean age and complaints at presentation (p=0.723, P=0.555, respectively). Ultrasound was performed on all patients. It was observed that the masses were located more frequently in the right breast in Group 1 (58.3%) and the left breast in Group 2 (p=0.386). In addition, it was noticed that the masses were most frequently located in the upper lateral quadrant of the breast in both groups (62.5% and 70.89%, respectively). The longest diameters of the masses were longer in group 1 than in group 2 (51.79±11.11 mm and 35.16±3.74 mm, respectively, p<0.001). Radiologically, most of the masses were reported as Breast Imaging Reporting and Data System (BI-RADS 3) in both groups (41.7% and 54.2%, respectively, p=0.444). Fine-needle aspiration biopsy (FNAB) was performed on nine patients in Group 1 and one in Group 2 (p=0.004). According to the FNAB reports, phyllodes tumors were detected in two patients, while the others were reported as fibroadenoma. The most common fibroadenomas were detected in the histopathological evaluations after surgical excision. In addition, a premalignant breast mass was detected in 6.2% of all patients.

Conclusion: We recommend surgical excision in children with large, rapidly growing breast masses or suspected phyllodes tumors.
