PHYLLODES TUMOR Figure 5-21 PHYLLODES TUMOR The cut surface of this benign phyllodes tumor demonstrates a well-circumscribed, lobulated tumor. The tumor appears to bulge forth and there are grooves in the cut surface that correspond to the elongated ducts and slit-like spaces seen on microscopic More about this image found in PHYLLODES TUMOR The cut surface of this benign phyllodes tumor demonstrate...

PHYLLODES TUMOR Figure 5-37 PHYLLODES TUMOR A: This core needle biopsy specimen highlights the extreme variability that can be seen in phyllodes tumor, with the area on the right bearing greater resemblance to fibroadenoma, and that on the lower left, malignant phyllodes tumor. B,C: High power More about this image found in PHYLLODES TUMOR A: This core needle biopsy specimen highlights the extreme...

PHYLLODES TUMOR Figure 5-22 PHYLLODES TUMOR This image shows the prototypical leaf-like projections of phyllodes tumor surmounted by a layer of benign epithelium and myoepithelium. More about this image found in PHYLLODES TUMOR This image shows the prototypical leaf-like projections of...

BENIGN PHYLLODES TUMOR Figure 5-27 BENIGN PHYLLODES TUMOR While the border of this tumor is well-circumscribed there is an uneven distribution of glands, an intracanalicular growth pattern, and a mildly hypercellular stroma supporting the diagnosis of benign phyllodes tumor.

MALIGNANT PHYLLODES TUMOR Figure 5-31 MALIGNANT PHYLLODES TUMOR A: This section illustrates the heterogeneity that can be encountered in phyllodes tumor, with a more hypocellular, myxoid-appearing area in the upper piece of tissue and a considerably more cellular section of tissue in the lower More about this image found in MALIGNANT PHYLLODES TUMOR A: This section illustrates the heterogeneity th...

MALIGNANT PHYLLODES TUMOR Figure 5-36 MALIGNANT PHYLLODES TUMOR A: At low power, this core needle biopsy appears to be composed entirely of spindle cells. The lesion is hypercellular. The tissue fragment at upper right has a focus of benign-appearing epithelium (arrow). B: Higher power shows More about this image found in MALIGNANT PHYLLODES TUMOR A: At low power, this core needle biopsy appears...
