Genomic landscapes of breast fibroepithelial tumors

Bin Tean Teh and colleagues report the genomic characterization of 100 breast fibroepithelial tumors, including benign fibroadenomas and benign, borderline and malignant phyllodes tumors. They identify mutations specific to phyllodes tumors and find somatic mutation patterns that distinguish borderline and malignant phyllodes tumors from the other tumor types.
