Findings can confirm benign nature of disease but are nonspecific, resembling fibroadenoma or phyllodes tumor (Indian J Pathol Microbiol 2005;48:260) Finding plump spindled mesenchymal cells is suggestive (Diagn Cytopathol 2005;32:345) Glandular elements have at least two cell layers - epithelial and myoepithelial. Guinebretire, JM. The purpose of this study is to examine the breast cancer risk overall among women with simple fibroadenoma or complex fibroadenoma and to examine the association of complex fibroadenoma with breast cancer through stratification of other breast cancer risks.
