Results:
Of the 114 patients, 87 eventually underwent surgery: among the 100 supposed benign papillomas, surgical excision revealed fibrocystic change or no residual lesion in nine cases, intraductal papilloma in 74, atypical papilloma in 13, papillary ductal carcinoma in situ (DCIS) in three and one invasive papillary carcinoma. The upgrade rate for an atypical papilloma or papilloma with adjacent foci of atypical ductal hyperplasia (ADH) and malignancy was 13% (95% CI = 7.1–21.2%) and 4% (95% CI = 1.1–9.9%), respectively. The mean lesion size (P = 0.041) was significantly larger when lesions were upgraded to malignancy. Other features were not significantly associated with pathological underestimation (P >  0.05).

Conclusion: 
Surgical excision should be considered for benign intraductal papillomas above 1.5 cm in size
