| Purpose: The purpose of this study was to analyze the histologic concordance of
sonographically guided core needle biopsy for phyllodes tumors or fibroepithelial
lesions with cellular stroma of the breast by comparing this with the outcomes of excision
biopsy and to identify any sonographic features that are helpful to predict phyllodes
tumors.
Materials and Methods: We retrospectively reviewed 60 breast masses that were
diagnosed as phyllodes tumors (n = 43) or fibroepithelial lesions with cellular stroma
(n = 17) on a sonographically guided core needle biopsy. The tumors were all subsequently
excised by surgery. The sonographic features were compared between the
phyllodes tumors and the non-phyllodes tumors according to the results of excision
biopsy.
Results: By the results on excision biopsy, there were 48 (80%) phyllodes tumors
and 12 (20%) non-phyllodes tumors. Phyllodes tumors were diagnosed at a rate of
90.7% (39/43) for the nodules with phyllodes tumors on the sonographically guided
core needle biopsy, and at a rate of 52.9% (9/17) for the nodules with fibroepithelial
lesions with cellular stroma on the sonographically guided core needle biopsy. On
sonography, heterogeneous internal echotexture (58% vs. 17%, respectively, p =
0.0239), clefts (56% vs. 17%, respectively, p = 0.0331) and horizontal linear striations
(71% vs. 33%, respectively, p = 0.0221) were significantly more frequent in the phyllodes
tumors than that in the non-phyllodes tumors.
Conclusion: Identification of a heterogeneous-internal echotexture, clefts and horizontal
linear striations on sonography might help differentiate phyllodes tumors from
non-phyllodes tumors. |
