ABSTRACT The purpose of this study was to investigate the risk of carcinoma in patients with a diagnosis of papilloma of the breast made on ultrasound large core biopsy or stereotactic vacuum-assisted biopsies.
This retrospective database review (2000-2007) included 130 patients with a papilloma diagnosed on preoperative biopsies or excisional surgery specimen. The mean patient age was 52 years (range, 20-80 years). The examinations included mammography and ultrasonography in all 130 patients. The final surgical histology was compared to preoperative biopsy diagnosis, and then factors associated with underestimation of malignancy were evaluated in univariate and multivariate analyses.
The preoperative histology was available for 63 patients. Benign papilloma had been identified by ductography in 34 patients and by preoperative biopsy in 48 patients. Mammography showed microcalcifications in 25 cases and nipple discharge was present in 59 patients. Malignancy was found on final histology in 8% of patients with initial diagnosis of benign papilloma. In this study group, age of more than 50 years, presence of nipple discharge and microcalcifications were found to be significantly related to the risk of malignancy (p=0.001, 0.05 and 0.02, respectively).
Since benign papilloma can be associated to malignancy at excisional biopsy, we still recommend surgical excision for papilloma especially when associated to identified risk factors of malignancy.

    ABSTRACT: The management of intraductal papillomas of the breast has been controversial; some advocate surgical excision of all lesions despite benign pathologic features, whereas others excise only those specimens with atypia. We conducted a retrospective review of 129 core-biopsy-proven papillomas of the breast with atypia (n = 43) and without atypia (n = 86) and determined the rate of missed carcinoma in surgically excised specimen in each group. Carcinoma was found in 22.5% of the surgically excised specimens in the atypia group (9/40) and in 3% of the surgically excised specimens in the no atypia group (1/29). Our findings confirm the practice that papillomas with atypical features should be excised, and suggest that in patients with adequate follow-up, benign papillomas may be managed conservatively.

    ABSTRACT: Management of papillary lesions of the breast identified during preoperative tissue diagnosis remains controversial. This study was designed to analyze the clinical factors associated with under-diagnosis of malignancy in breast papillary lesions. Patients with a preoperative tissue diagnosis of benign or atypical papillary lesions, who received surgical excision between 1991 and 2005, were identified. Age of diagnosis, family history of breast cancer, presentation of nipple discharge, palpable mass, mammogram grading, size of lesion, and final pathological diagnosis were analyzed. Tissue sections were reviewed to confirm the diagnosis of malignancy and reasons of discrepancy. A total of 205 women with 228 papillary lesions were studied. The median age was 42 (range, 12-83) years. Malignancies were diagnosed after surgery in 21 cases (9.2%). Patients aged 45 years or older and atypical lesions according to fine needle aspiration cytology (FNAC) or core needle biopsy (CNB) were associated with higher risk for postoperative malignant diagnosis with P values of 0.0008 and < 0.0001, respectively. Pathology review of 19 lesions with malignancy revealed that reasons for preoperative nonmalignant diagnosis were borderline lesions in nine (47.3%), sampling problem in six (31.5%), interpretation error in three (15.7%) and uninterpretable sample in one (5.2%). In this cohort, 9.21% of preoperative nonmalignant papillary lesions were converted to malignant diagnosis after surgery. Atypical lesions and patients aged 45 years or older were significant factors associated with such conversion. Surgical excision should be considered for papillary lesions of breast, especially for patients with the identified risk factors.

    ABSTRACT: This study was designed to evaluate the clinical and pathologic parameters of benign papillomas diagnosed on core needle biopsy (CNB) and predict malignancy risk after surgical excision. We retrospectively reviewed clinicopathologic findings for 160 CNB-diagnosed benign papillomas followed by surgical excision from 154 patients. Ten (6.3%) of the excised lesions were diagnosed as malignant. Univariate analysis showed that those that were palpable on physical examination, detected as a mass on mammography, or >1 cm on sonography were significantly associated with malignancy. In multivariate analysis, lesions that were palpable (odds ratio (OR), 29.2; 95% confidence interval (CI), 4.06-209.58; P = 0.001) or detected as a mass (OR, 5.68; 95% CI 1.08-29.87; P = 0.04) remained significantly associated with malignancy. In a CART analysis, including all variables, lesions that were palpable and associated with a mass on mammogram were confirmed as malignant. Breast lesions diagnosed as benign papillomas on CNB had a 6.3% risk of being malignant. The risk was highest for lesions that were palpable and detectable as a mass on a mammogram. In addition, the low-risk patients avoid immediate surgical excision, although they should be followed carefully.
