==Phyllodes tumour==
The name comes from the word "leaf"; with imagination or psychotropic drugs, it may look like one (the epithelial component = the veins of the leaf).

Features:
Features - either 1, 2 or both of the following:
*Large slit-like spaces.
#Large slit-like spaces - '''key feature'''.
*Cellular stroma that may be [[myxoid stroma|myxoid]].
#Cellular stroma - '''key feature'''. †
#*May be [[myxoid stroma|myxoid]].
*+/-Infiltrative border.
*+/-Mitoses.
*+/-Mitoses.
*May have "malignant border" -- "pushing border" / "infiltrative border".
*+/-Nuclear atypia.
*+/-"Stromal overgrowth" ~ stroma fills microscopic field.
 
Notes:
* † Large slit-like spaces are required for a benign phyllodes tumour.
** Slit-like spaces may absent in a borderline phyllodes ''or'' a malignant phyllodes.
** A cellular tumour without features suggestive of malignancy and without slit-like spaces is a ''[[cellular fibroadenoma]]''.
 
DDx:
*[[Fibroadenoma]].
*Sarcoma.
