Accessibility Arch Pathol Lab Med. Methods A retrospective review was performed of patients . Giant fibroadenoma. 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). At a mean follow-up of 2 years, we found a low incidence of malignancy in complex fibroadenomas. However, women with complex fibroadenoma were more likely to have other, concomitant high-risk histologic characteristics (e.g., incomplete involution and PDWA).
