Although malignant transformation in FA is rare, there is evidence of an association with breast carcinoma, particularly in middle-aged females with associated risk factors, such as a strong family history and/or BRCA-1/2 mutations. Complex fibroadenomas are often smaller than simple fibroadenomas (1.3 cm compared with 2.5 cm in simple fibroadenomas). However, we cannot answer medical or research questions or give advice.

Fibroadenomas are benign while phyllodes tumor range from benign, indolent neoplasms to malignant tumors capable of distant metastasis. May be either adult or juvenile type. To determine the cytomorphological features of complex type fibroadenoma (CFA), we reviewed fine needle aspiration (FNA) cytology with correlation to its histopathology findings, and compared them with non-complex type fibroadenoma (NCFA). No stromal overgrowth is seen. These tumors are usually benign, but they can come back and cause the breast to look abnormal if not totally removed.

Over time, a fibroadenoma may grow in size or even shrink and disappear. The term fibroadenoma combines the words "fibroma," meaning a tumor made up of fibrous tissue, and "adenoma," a tumor of gland tissue. ~50% of these tend to be lobular carcinoma in situ (LCIS), ~20% infiltrating lobular carcinoma, ~20%ductal carcinoma in situ (DCIS), and the remaining 10% are infiltrating ductal carcinoma. biopsy specimens (, Disordered but morphologically normal appearing ducts and lobules, Prominent pericanalicular adenosis-like epithelial proliferation with little intervening stroma, Generally does not form a clinically dominant mass, Individual lobule or few groups of lobules with collagenized interlobular stroma and loss of On gross pathology, a rubbery, tan colored, and Please enable it to take advantage of the complete set of features! 2021 Jan 10;13(1):e12611.
