Fibroadenoma is a very common benign neoplasm typically occurring in patients between the ages of 20 and 35 years. Analyses were performed overall, within subgroups of involution status, with other demographic characteristics (age, year of biopsy, indication for biopsy, and family history), and with histologic characteristics, including overall impression [nonproliferative disease, proliferative disease without atypia (PDWA), or atypical hyperplasia].

Complex fibroadenomas may increase the risk of breast cancer. 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) Visual survey of surgical pathology with 11,912 high-quality images of benign and malignant neoplasms & related entities. FOIA However, women with complex fibroadenoma were more likely to have other, concomitant high-risk histologic characteristics (e.g., incomplete involution and PDWA). 2008;190 (1): 214-8. Please enable it to take advantage of the complete set of features! (a) In a 42 year old woman with a right axillary palpable lump, the mammogram shows a well-defined, gently lobulated, oval nodule in the right axilla (white arrow).Accessory breast tissue is also seen (red arrow). Glandular elements have at least two cell layers - epithelial and myoepithelial. Fibroadenoma is the commonest solid benign lesion that can exist as a solitary mass or multiple masses in the breasts. Methods: Complex fibroadenoma does not confer increased breast cancer risk beyond other established histologic characteristics. The term fibroadenoma combines the words "fibroma," meaning a tumor made up of fibrous tissue, and "adenoma," a tumor of gland tissue. Bookshelf Epub 2022 May 31. AJR Am J Roentgenol.
