(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). We sought to evaluate the incidence of complex fibroadenoma on biopsy and to propose decision criteria for managing patients with these breast lesions.

Aims: Breast myxoid fibroadenomas (MFAs) are characterized by a distinctive hypocellular myxoid stroma, and occur sporadically or in the context of Carney complex, an inheritable condition caused by PRKAR1A-inactivating germline mutations. The pathology is in the stroma; so, the lesion is really a misnomer by the naming rules. No cytologic atypia is present. Unauthorized use of these marks is strictly prohibited. We found that 15 cases fulfilled the diagnostic criteria of CFA, in which 7 (46.7 %) had an FNA diagnosis of "suspicious for malignancy" or "indeterminate" while only 2 NCFA cases had that of "indeterminate" (p = 0.004). 2021 Jan 10;13(1):e12611. sclerosing adenosis and Fibroadenoma - slit-like spaces (webpathology.com), Fibroadenoma - lobulated appearance (webpathology.com), Tubular adenoma of the breast (webpathology.com), http://www.pathconsultddx.com/pathCon/diagnosis?pii=S1559-8675%2806%2970216-9, http://www.imagingpathways.health.wa.gov.au/includes/dipmenu/image/image.html, http://www.breastpathology.info/fibro_variants.html#juvenile, http://www.breastpathology.info/fibro_variants.html#complex, https://librepathology.org/w/index.php?title=Fibroadenoma&oldid=51069, Attribution-NonCommercial-ShareAlike 4.0 International, abundant (intralobular) stroma usu.

IHC can aid in visualizing the myoepithelial layer. Our study was to determine the select cytologic features that can accurately distinguish FA from PT. There are numerous reports that the general risk of developing cancer in the breast parenchyma is elevated among women with complex fibroadenomas; these women are 3.1-3.7 times more likely to develop breast cancer than women in the general population (compared with a relative risk of 1.9 times in women with non-complex fibroadenomas). Complex fibroadenomas were diagnosed in 63 of 401 fibroadenomas (15.7%) found at consecutive percutaneous needle or excisional surgical bi-opsy. Focally, the lesion approaches the inked margin; partial lesion transection cannot be excluded. Richard L Kempson MD. Sosin M, Pulcrano M, Feldman ED, Patel KM, Nahabedian MY, Weissler JM, Rodriguez ED.

At the time the article was last revised Patrick J Rock had no recorded disclosures. At a mean follow-up of 2 years, we found a low incidence of malignancy in complex fibroadenomas. Med J Aust. Please enable it to take advantage of the complete set of features! Conclusion: Approximately 16% of fibroadenomas are complex. Epub 2021 Jul 12 doi: 10.1371/journal.pone.0253764. Complex fibroadenoma is a sub type of fibroadenoma harbouring one or more of the following features: epithelial calcifications papillary apocrine metaplasia sclerosing adenosis and cysts larger than 3 mm. However, we cannot answer medical or research questions or give advice. ; Chen, YY. When histopathology on core biopsy reveals a higher-risk lesion, such as atypical lobular hyperplasia, excisional biopsy may be indicated to rule out malignancy. Women with complex fibroadenomas may therefore be managed with a conservative approach, similar to the approach now recommended for women with simple fibroadenomas.
