"Atypical ductal hyperplasia is associated with the use of postmenopausal hormone treatment and its rates have decreased with the decline in use of this treatment," Menes added.
The adjusted odds ratio for developing breast cancer was 2.76 for women with atypical ductal hyperplasia, 5.24 for those with atypical lobular hyperplasia, and 8.12 for women with both histologic abnormalities.
Atypical ductal hyperplasia may secondarily involve benign breast lesions, including intraductal papillomas, fibroepithelial lesions, radial scars, and adenosis.
Atypical ductal hyperplasia (ADH), lobular carcinoma in situ (LCIS) and atypical lobular hyperplasia (ALH) may also present with calcifications that may exhibit high density, clustered punctuate calcification and tending to lack the characteristic features of DCIS such as rod shapes, ductal distribution and branching.
There's a continuum from normal ductal epithelium to ductal hyperplasia to atypical ductal hyperplasia, which can progress to breast cancer, Dr.
Cancerization of lobules and atypical ductal hyperplasia adjacent to ductal carcinoma in situ of the breast: significance for breast-conserving therapy.
Panel E shows atypical ductal hyperplasia: these proliferations are characterised by a combination of architectural complexity with partially formed secondary lumens and mild nuclear hyperchromasia in the epithelial-cell population.
Other associated findings included a radial scar, multifocal atypical ductal hyperplasia, and lobular intraeithelial neoplasia.
Atypical ductal hyperplasia (ADH), lobular carcinoma in situ (LCIS) and atypical lobular hyperplasia (ALH) may also present with calcifications which may exhibit high density, clustered punctuate calcification and tend to lack the characteristic features of DCIS such as rod shapes, ductal distribution and branching.
Of the total 108 false-positive findings, 39 were diagnosed as atypical ductal hyperplasia. Significantly more cases were detected by MRI (36) than by mammography (10) or ultrasound (4).
Investigators classified all benign breast biopsies as either nonproliferative, proliferative without atypia, or atypical hyperplasia, with the atypical hyperplasias being subclassified into atypical lobular hyperplasia or atypical ductal hyperplasia. Odds ratios for breast cancer risk according to pathologic category of benign breast disease were then calculated after adjustment for length of study follow-up, age at menarche, family history of breast cancer, body mass index, menopausal status, and history of hormone therapy use.
Our case selection criteria included core biopsies with a diagnosis of ALH, with no other atypical pathology present (ie, biopsies that contained ALH along with flat epithelial atypia, atypical ductal hyperplasia, LCIS, DCIS, or IC were excluded).
In our present study, the benign lesions are also seen in associated with the epithelial proliferative lesions with atypia, among the benign lesions the commonest benign lesion fibrocystic disease was mostly associated with atypical hyperplasia of ductal type or atypical ductal hyperplasia (ADH) constituting about 4 cases (28.5%), followed by fibrocystic disease with columnar cell change and intraductal papilloma associated with atypical ductal hyperplasia in 3 cases (21.4%)each, followed by sclerosing adenosis with ADH and fibroadenoma with ADH of 2 cases(14.2%) each, simple adenosis with atypical lobular hyperplasia (ALH) comprised 2 cases (14.2%) (Table 7).
