Purpose: To evaluate the surgical outcomes of fibroepithelial lesion with cellular stroma (FELCS) diagnosed at sonography guided core needle biopsy of breast masses, and to determine whether the clinical and imaging features of this lesion could predict the presence of a phyllodes tumor.
Materials and Methods: We retrospectively reviewed the pathologic results of sonography guided core needle biopsy of solid breast masses. A total of 55 FELCS diagnosed with this procedure that underwent subsequent surgical excision were included in this study; their medical records and radiologic images were retrospectively reviewed.
Results: The results of the surgical excision revealed 22 (40%) phyllodes tumors and 33 (60%) non-phyllodes tumors: 30 (54.6%) fibroadenomas, 1 (1.8%) adenosis, 1 (1.8%) fibrocystic changes and 1 (1.8%) fibroadenomatous hyperplasia. Lesion size and patient age were significantly different between phyllodes tumors and nonphyllodes tumors groups (32.2 ± 14.07 mm/22.4 ± 13.64 mm, p=0.0078, 43.5 ± 11.60 years/36.5 ± 10.25 years, p=0.0207). Among the sonographic features, only cleft was significantly more visible in phyllodes tumors than in non-phyllodes tumors (n=14 (70%)/n=6 (30%), p=0.0016).
Conclusion: The size of the lesions, the age of the patients, and the sonographic features of cleft were the significant helpful variables to predict phyllodes tumors among FELCS diagnosed at breast core biopsy.
