However, women with complex fibroadenoma were more likely to have other, concomitant high-risk histologic characteristics (e.g., incomplete involution and PDWA). In this review, the pathology of the fibroadenoma and phyllodes tumour is revisited, with emphasis on diagnostic and management implications.
