Fibroadenomas may demonstrate estrogen and progesterone sensitivity and may grow during pregnancy. Fibroadenoma, abbreviated FA, is a common benign tumour of the breast. Because of their high mobility, they are also referred to as mouse in the breast/breast mouse. 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). 2004 Feb;21(1):48-56.

Pleomorphic adenoma is a common benign salivary gland neoplasm characterised by neoplastic proliferation of epithelial (ductal) cells along with myoepithelial components, having a malignant potentiality. MeSH Although no significant difference was noted in patients' age and tumor size between CFA and NCFA, 5 CFA cases (33.3 %) were accompanied by the presence of carcinoma in the same breast or the contralateral breast while no NCFA cases had carcinoma in the breast. A. Said SM, Visscher DW, Nassar A, Frank RD, Vierkant RA, Frost MH, Ghosh K, Radisky DC, Hartmann LC, Degnim AC. They fall under the broad group of adenomatous breast lesions. FNA smears from CFA cases showed discohesiveness, enlarged nuclei, prominent nucleoli, and fewer myoepithelial cells more often than NCFA.

Can occur at any age, but most patients are young and in their reproductive age group. Risk appears to be slightly higher in those patients with a positive family history of breast cancer. They fall under the broad group of "adenomatous breast lesions".. Complex fibroadenomas are often smaller than simple fibroadenomas (1.3 cm compared with 2.5 cm in simple fibroadenomas).
