The average fibroadenoma is anywhere from the size of a marble up to 2.5 centimeters (cm) in diameter. Background: 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). The study included women aged 18-85 years from the Mayo Clinic Benign Breast Disease Cohort who underwent excisional breast biopsy from 1967 through 1991. Ann Surg Oncol. National Library of Medicine
Fibroadenoma pathophysiology - wikidoc We sought to evaluate the incidence of complex fibroadenoma on biopsy and to propose decision criteria for managing patients with these breast lesions. http://surgpathcriteria.stanford.edu/,
