Final histological diagnosis of benign cases classified as inadequate or indeterminate. Among inadequate cases, the most frequent histological type was mastopathy (fibrocystic disease) (29/75 cases, 38.6%), followed by fibroadenoma (18/75, 24.0%) and intraductal papilloma (4/75, 5.3%). There were no significant differences in the frequencies of these histological types. Among indeterminate cases, the histological types included mastopathy (16/54, 30.0%), fibroadenoma (15/54, 27.8%) and intraductal papilloma (14/54, 26.0%). Phyllodes tumor was seen in three cases (5.6%). There were no significant differences in the frequencies of these histological types. Papilloma was significantly more frequent in indeterminate cases than in inadequate cases (26% vs 5%; *P = 0.0014). Dark gray, inadequate; light gray; indeterminate. Phyllodes, phyllodes tumor.
