Abbreviations
Phyllodes tumor (PT)
Synonyms
Cystosarcoma phyllodes (older term, out of favor)
Definitions
PT: Hypercellular fibroepithelial neoplasm with characteristic leaf-like architecture
Biphasic tumor composed of stromal and epithelial elements
Characterized by leaf-like stromal projections into epithelium-lined clefts
Phyllodes: "Leaf-like" in Greek
Clefts between projections form distinctive "cystic" spaces
Phyllodes tumors can be benign, borderline, or malignant
Cannot reliably distinguish with imaging
Graded at histopathology based on: Mitoses, stromal cellularity, stromal overgrowth and borders
Benign PT
< 5 mitoses per 10 HPF
Low stromal cellularity, no stromal overgrowth, circumscribed margins
