periductal stromal tumor breast pathology outlines

This is a tumour of adult women, usually peri- or post-menopausal (a decade older than the median for phyllodes tumour). PSS is a distinct, low-grade breast sarcoma with no clinical or radiological specificity. Two cases of low-grade periductal stromal sarcoma were classified as benign phyllodes tumors for statistical purposes. We confirm that PST shares morphologic and immunophenotypic similarities with phyllodes tumor (PT).
