Phyllodes tumors are uncommon biphasic fibroepithelial neoplasms
of breast, comprising less than 1% of all breast neoplasms. We
therefore aimed to present the case with its microscopic findings. In
this article, we report a 59-year-old female admitted to the general
surgery department with a rapidly, enlarging, palpable mass in right
breast. After histopathological examination, it was diagnosed as
borderline phyllodes tumor with extensive squamous metaplasia.
Metaplastic changes are infrequent in the stromal and epithelial
component of these tumors. Extensive squamous metaplasia within
phyllodes tumor is rare and may occur in benign, borderline and
malign subtypes.
