Benign papillary neoplasms of the breast: mammographic findings

The clinical presentation, pathologic characteristics, and mammographic/ductographic (also known as galactographic) findings were reviewed in 77 patients with histologically proved benign papillary neoplasms of the breast. Patients were classified as having either solitary or multiple papillomas. Patients with multiple papillomas were further subclassified as having either central or peripheral papillomas. Fifty-one patients (66%) had solitary papillomas. Thirty-seven of these patients were symptomatic; 36 had spontaneous nipple discharge, and one had a palpable mass. Ductography was positive in 32 of the 35 patients who underwent the procedure. In the 14 asymptomatic patients, subareolar (n = 10) and peripheral (n = 4) mammographic abnormalities prompted biopsy. Fourteen patients (18%) had multiple peripheral papillomas, and one patient also had bilateral central solitary papillomas. Eleven of these patients were asymptomatic, while two presented with palpable abnormalities and one with spontaneous bilateral discharge. Mammographic findings included microcalcifications (n = 5) and clustering nodules (n = 2). Associated atypical ductal hyperplasia was found in six (43%) of the 14 patients with multiple peripheral papillomas. Some of these patients also had lobular carcinoma in situ and radical scars. Twelve patients had multiple central papillomas; all presented with spontaneous nipple discharge and had positive ductograms.

Underestimation of the presence of breast carcinoma in papillary lesions initially diagnosed at core-needle biopsy

PURPOSE: To retrospectively determine the degree of underestimation of breast carcinoma diagnosis in papillary lesions initially diagnosed at core-needle biopsy. MATERIALS AND METHODS: Institutional review board approval and waiver of informed consent were obtained for this HIPAA-compliant study. Mammographic database review (1994-2003) revealed core biopsy diagnoses of benign papilloma (n=38), atypical papilloma (n=15), sclerotic papilloma (n=6), and micropapilloma (n=4) in 57 women (mean age, 57 years). Excisional or mammographic follow-up (>or=2 years) findings were available. Patients with in situ or invasive cancer in the same breast or patients without follow-up were excluded. Findings were collected from mammography, ultrasonography, core technique, core biopsy, excision, and subsequent mammography. Reference standard was excisional findings or follow-up mammogram with no change at 2 years. Associations were examined with regression methods. RESULTS: In 38 of 63 lesions, surgical excision was performed; in 25 additional lesions (considered benign), follow-up mammography (24-month minimum) was performed, with no interval change. In 15 lesions, 14-gauge core needle was used; in 48, vacuum assistance (mean cores per lesion, 8.7). Carcinoma was found at excision in 14 of 38 lesions. Core pathologic findings associated with malignancy were benign papilloma (n=1), sclerotic papilloma (n=1), micropapilloma (n=2), and atypical papilloma (n=10). Frequency of malignancy was one (3%) of 38 benign papillomas, 10 (67%) of 15 atypical papillomas, two (50%) of four micropapillomas, and one (17%) of six sclerotic papillomas. Excisional findings included lobular carcinoma in situ (n=2), ductal carcinoma in situ (n=7), papillary carcinoma (n=2), and invasive ductal carcinoma (n=3). Low-risk group (micropapillomas and sclerotic and benign papillomas) was compared with high-risk atypical papilloma group. Core findings were associated with malignancy at excision for atypical papilloma (P=.006). Lesion location, mammographic finding, core number, or needle type were not associated (P>.05) with underestimation of malignancy at excision. CONCLUSION: Benign papilloma diagnosed at core biopsy is infrequently (3%) associated with malignancy; mammographic follow-up is reasonable. Because of the high association with malignancy (67%), diagnosis of atypical papilloma at core biopsy should prompt excision for definitive diagnosis.     

Predictive value of galactographic patterns for benign and malignant neoplasms of the breast in patients with nipple discharge

The purpose was to identify features of malignant and non-malignant neoplastic breast disease on galactography and to estimate their predictive value. This is the largest reported study correlating galactographic morphological patterns with histopathology and the only blinded study. The study included 351 consecutive galactograms and 161 breast biopsies performed in patients with nipple discharge over a 10-year period. Three radiologists, blinded to clinical data and histological results, re-evaluated 158 previously performed galactograms of patients who had undergone excision biopsy. Extravasation or incomplete filling precluded reading in 9.5% of examinations. Among the remaining 143 examinations there were 11 cancers (7.7%), 56 papillomas (39.2%), 19 cases of intraductal papillomatous proliferation (13.3%), 55 cases of fibrocystic or secretory disease (38.5%) and two normals. A "filling defect/cut-off" pattern (n = 90) was found in 6 cancers (6.7%) and 58 cases of papilloma or papillomatous proliferation (64.4%). A "leafless tree" pattern was found only in benign cases (n = 12; 8.4%). In 32 of 143 cases (22.4%) a "ductal ectasia" pattern was present, in one case of which (3.1%) cancer was found. Cancer was identified in two of four cases with an "architectural distortion" pattern. Cancer is rare in patients with nipple discharge. A tendency towards a lower incidence of cancer associated with the "ductal ectasia" and "leafless tree" patterns was found. No statistical evidence was found to indicate that galactography provides an effective prospective diagnosis of malignancy. However, an abnormal galactogram strongly correlated (p < 0.001) with the presence of a breast neoplasm when both benign and malignant tumours were considered. The most important role played by galactography is in the localization of breast neoplasms and in the choice of appropriate surgical therapy.     

The diagnostic value of galactography in patients with nipple discharge

To evaluate preoperative galactographic findings in the differentiation between the benign and malignant lesions in patients presenting spontaneous nipple discharge without mass. Of the 215 patients who have undergone the galactography, 181 cases with abnormal galactography had surgery performed. All galactrograms were reviewed and galactographic findings were correlated to the pathological results to determine diagnostic differentiation. Of the 181 cases we operated on, 112 cases were macroscopically bloody, with 30 cases having cancers (26.8%). Fifty-four cases with serous discharge had seven cancer cases (13.0%). No cancer cases with other color discharge were found. Of the 37 cancer cases, 11 cases had lesions located in the main mammary ducts (lactiferous duct and the segmental duct) (29.7%) and 26 cases had lesions in the peripheral ducts (the subsegmental duct and its branches) (70.3%) (P<.05). Of 113 cases with benign proliferative ductal lesions, 88 cases were located in the main mammary duct (77.9%) and 25 cases in the peripheral mammary duct (22.1%) (P<.05). Otherwise, 29 cancer cases (82.9%) had ductal obstructions and 28 cancer cases (75.7%) had irregular intraductal defects that appeared in the galactograms, which is different from the 113 benign proliferative ductal lesion cases that had 88 cases (71.7%) with ductal dilatation and 90 cases (79.6%) with lobular or smooth intraductal defects (P<.05). These results showed that the cancer cases had a higher rate of locating in the peripheral duct, irregular intraductal duct defects, and ductal obstruction, and a lower rate associated with ductal dilatation or torsion. The galactographic findings were evaluated using the tumor location, types of intraductal defects, ductal obstruction, and dilatation. Preoperative diagnostic galactography is useful in differentiating between the benign or malignant lesions in patients with spontaneous nipple discharge.

Case report: galactography-guided wire localization of an intraductal papilloma

Galactography is used to evaluate spontaneous unilateral nipple discharge by catheterization of the duct orifice and instillation of radiopaque contrast material. The most common cause of a bloody discharge is an intraductal papilloma which appears as a smooth lobulated intraluminal filling defect or a solitary obstructed duct on galactography. Carcinomas may be the cause of up to 13% [1] of abnormal nipple discharge and cannot be reliably distinguished from papillomas at galactography. Thus any intraductal filling defect or irregularity in symptomatic patients should be surgically evaluated to obtain a tissue diagnosis. Unfortunately, the histologic examination of the biopsy specimen does not always identify the lesion seen at galactography [2]. A potentially more reliable method of locating lesions identified on galactography is described. Chow, J. S. (2001). Clinical Radiology56, 72-73.

Early breast cancer: detection of recurrence after conservative surgery and radiation therapy

To determine the clinical and mammographic features of recurrent breast cancer after tumorectomy and radiation therapy, the authors reviewed the clinical history and serial mammograms of 48 patients with suspected recurrence. Of patients with recurrent disease, seven had positive mammograms alone, nine had positive findings at physical examination alone, and eight had both positive mammograms and positive results of physical examination. Positive mammographic findings included the development of new fine calcifications (six patients), a new mass (five patients), mass and calcifications (one patient), increasing opacity (two patients), or skin thickening (one patient). Patients in whom the breast recurrence was detected mammographically alone were less likely to develop metastatic disease in subsequent follow-up than when results of physical examination were positive at the time of breast recurrence. Serial mammographic and clinical examinations are complementary for optimal detection of recurrence after conservative surgery and radiation therapy.

Invasive papillary carcinoma of the breast: mammographic appearance

The mammographic findings in 18 patients with invasive papillary carcinoma were studied retrospectively. The mammograms of 10 patients showed a multinodular pattern, and seven patients had solitary nodules. One patient had an irregular, ill-defined mass in the retroareolar region. Two patients were found to have carcinoma in the contralateral breast, and two patients had intraductal carcinoma adjacent to the invasive papillary carcinoma. The varied mammographic features that may occur with this rare breast malignancy are discussed.     

Galactography with contrast and dye--a two stage radiological/surgical approach to serous or bloody nipple discharge

Patients with serous or bloody nipple discharge arising from a single duct are treated by a joint radiological/surgical approach at our institution. Two galactograms are performed; the first with contrast medium alone to identify any lesion and the second, one hour prior to surgery, using both contrast and methylene blue. This defines the area for the surgeon ensuring the involved duct is removed. Several case histories are described and the galactographic technique is detailed.     

Mammographic features predicting an extensive intraductal component in early-stage infiltrating ductal carcinoma.

Several studies have shown that the presence of an extensive intraductal component in patients with infiltrating ductal carcinoma is a major factor for predicting local recurrence after breast-conserving surgery and radiotherapy. A prospective study of 101 consecutive mammograms in patients with stage I or II infiltrating ductal carcinoma was performed to determine the predictive values of mammographic features in determining the presence or absence of an extensive intraductal component. Thirty-five (35%) of the lesions contained a pathologically verified extensive intraductal component. Sixty-five percent (22/34) of lesions showing mammographic evidence of calcifications with or without a mass were associated with an extensive intraductal component (p less than .001). Lesions with calcifications greater than 3 cm in extent were significantly (p less than .05) more likely to have an extensive intraductal component (9/10; 90%) than those with calcifications less than 3 cm in extent (13/24; 54%). Only 17% (8/46) of patients in whom mammograms showed only a mass or architectural distortion and 24% (5/21) of patients who had a mass palpable clinically or who had normal findings on mammograms had lesions with an extensive intraductal component. We conclude that infiltrating ductal carcinomas associated with calcifications on mammography, especially if the calcifications are extensive, are likely to be associated with an extensive intraductal component. Carcinomas without calcifications that show masses or architectural distortion on mammography, or carcinomas with palpable masses and normal findings on mammography, are unlikely to have an extensive intraductal component.
