Dupont WD, Page DL, Parl FF, Vnencak-Jones CL, Plummer WD Jr, Rados MS, Schuyler PA. Management of fibroadenoma of the breast. This model affords the opportunity for investigators to study the process of mammary carcinogenesis over a very short latency and to investigate early events in this process. FNA smears from CFA cases showed discohesiveness, enlarged nuclei, prominent nucleoli, and fewer myoepithelial cells more often than NCFA. When histopathology on core biopsy reveals a higher-risk lesion, such as atypical lobular hyperplasia, excisional biopsy may be indicated to rule out malignancy. Complex type; Fibroadenoma; Fine needle aspiration. Most of the time, sclerosing adenosis lacks cytologic atypia.
