The cases of atypical ductal hyperplasia
associated with cancer reached a peak of 4.
In contrast, patients who were premenopausal when they had a breast biopsy showing atypical ductal hyperplasia
had a 2.
Can mammographic findings help discriminate between atypical ductal hyperplasia
and ductal carcinoma in situ after needle core biopsy?
Distribution of Intranuclear Inclusions in Usual Intraductal Hyperplasia (UIDH), Atypical Ductal Hyperplasia
(ADH), and Low-Grade Ductal Carcinoma In Situ (LG-DCIS) Lesion Type None Acidophilic (a) White UIDH (n = 40) 8 (20.
Although prior studies (2,3) have examined the average amount of sectioning needed with respect to stereotactic core biopsies performed to evaluate radiologically identified calcifications and associated lesions (ie, atypical ductal hyperplasia
and in situ or invasive carcinoma), to our knowledge, no study has specifically examined the amount of sectioning necessary with MRI-guided cores.
First, similar to PAC, the frequency of atypical ductal hyperplasia
is increased in biopsies that have prominent apocrine adenosis.
Atypical ductal hyperplasia
, atypical lobular hyperplasia, and interpretation of a new borderline lesion.
The diagnosis and management of pre-invasive breast disease: ductal carcinoma in situ (DCIS) and atypical ductal hyperplasia
(ADH)--current definitions and classification.
For instance, the issue of whether a primary diagnosis of atypical ductal hyperplasia
(ADH) diagnosed on NCB warrants a subsequent excisional biopsy has been debated and extensively investigated.
The excision showed only fibrocystic changes in 5 cases, atypical ductal hyperplasia
in 3 cases, DCIS alone in 66 cases, and invasive carcinoma in 17 (19%) cases.
How many sections of breast core needle biopsy specimens are necessary to ensure that all atypical ductal hyperplasia
lesions and atypical small acinar proliferations are sampled?
13] Studies of atypical foci in breast core needle biopsy specimens, most commonly in the form of atypical ductal hyperplasia
(ADH), have not been performed.
