We evaluated the clinical and imaging presentations of complex fibroadenomas; compared pathology at core and excisional biopsy; and contrasted age, pathology, and size of complex and simple fibroadenomas using the Student's t test. Contributed by Gary Tozbikian, M.D. 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 key to breast pathology is the myoepithelial cell. Complex fibroadenomas were diagnosed in 63 of 401 fibroadenomas (15.7%) found at consecutive percutaneous needle or excisional surgical biopsy. 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.

In analyses stratified by involution status and PDWA, complex fibroadenoma was not an independent risk marker for breast cancer. FOIA Tumor-associated autoantibodies from mouse breast cancer models are found in serum of breast cancer patients. It should be distinguished from other benign masses of the breast by proper evaluation and management. 2010 Dec;17(12):3269-77. doi: 10.1245/s10434-010-1170-5.
