Clipboard, Search History, and several other advanced features are temporarily unavailable. However, women with complex fibroadenoma were more likely to have other, concomitant high-risk histologic characteristics (e.g., incomplete involution and PDWA). Materials and methods: Fibroadenoma is the commonest solid benign lesion that can exist as a solitary mass or multiple masses in the breasts. Multinucleated stromal giant cells in mammary fibroepithelial neoplasms. In analyses stratified by involution status and PDWA, complex fibroadenoma was not an independent risk marker for breast cancer. .style2 {font-family: Arial, Helvetica, sans-serif} 2022 Feb;75(2):133-136. doi: 10.1136/jclinpath-2020-207062. .

Breast cancer risk (observed versus expected) across fibroadenoma levels was assessed through standardized incidence ratios (SIRs) by using age- and calendar-stratified incidence rates from the Iowa Surveillance, Epidemiology, and End Results registry. Fibroadenoma was identified in 2136 women [noncomplex, 1835 (85.9%); complex, 301 (14.1%)]. Focally, the lesion approaches the inked margin; partial lesion transection cannot be excluded.
