Bethesda, MD 20894, Web Policies | Log in | 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). We further re-assessed detailed characteristics of each FNA smears to identify cytomorphological features of CFA. ~50% of these tend to be lobular carcinoma in situ (LCIS), ~20% infiltrating lobular carcinoma, ~20%ductal carcinoma in situ (DCIS), and the remaining 10% are infiltrating ductal carcinoma.
