Periductal stromal tumor: the periductal stromal tumor is an entity that histologically overlaps with malignant phyllodes tumor, the main difference being the absence of leaf-like processes. Rare sites of metastasis, such as to the parotid region, have also been described.[13]. FOIA Periductal stromal hyperplasia (PDSH) has been known to present as densities in the breast or vague nodularities, while periductal stromal sarcoma (PDSS) historically presents as a mass, often mimicking fibroadenomas or hamartoma. A 1.3-cm, irregular mass with microcalcifications was also detected in the upper outer quadrant of the right breast and a 1.3-cm irregular mass was detected in the upper outer quadrant of the left breast. 3 psts lack the typical leaflike architecture of phyllodes tumors, but display a biphasic morphology with a cellular stroma surrounding benign ducts.
