However, women with complex fibroadenoma were more likely to have other, concomitant high-risk histologic characteristics (e.g., incomplete involution and PDWA). Complex fibroadenomas are often smaller than simple fibroadenomas (1.3 cm compared with 2.5 cm in simple fibroadenomas).

Robert V Rouse MD rouse@stanford.edu. Simple: Most fibroadenomas are the simple type; they are more common in younger people.There's usually just one mass in your breast, with a definite border and very uniform cells. Can occur at any age, median age of 25 years ( J R Coll Surg Edinb 1988;33:16 ) Juvenile fibroadenoma generally occurs in younger and adolescent patients < 20 years; reported in children at a very young age ( Am J Surg Pathol . FOIA Med J Aust. Risk appears to be slightly higher in those patients with a positive family history of breast cancer. 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). Complex fibroadenomas were half the size (average, 1.3 cm; range, 0.5-2.6 cm) of noncomplex fibroadenomas (average, 2.5 cm; range, 0.5-7.5 cm) (p < 0.001).
