Papilloma
• Histology
• If associated with dilated duct
then intracystic papilloma vs
non dilated sometimes called
ductal adenoma
• Proliferation of duct epithelium
on frond-forming fibrovascular
stroma
• Difficult dx by cytology or
frozen so excision
recommended
Papilloma
Identified
• Presents as Pathologic nipple discharge in 86% of
central and 29% of peripheral lesions (where they are
more commonly diagnosed as palpable mass or
mammographic density)
• Associated Risk
• 1% of breast cancer presents as PND and less than
10 % PND is caused by cancer
• Risk goes up with mammographically detected or
palpable (peripheral) papillomas and with Age
• Long-term RR is 2.5 to 3X
Papilloma
Papillomatosis
• Histology
• Also called epitheliosis
• More consistent with micropapillary ductal hyperplasia
than multiple papillomas.
• A ductal hyperplastic lesion in which a fibrovascular
structure supports papillary epithelial hyperplasia
• May occur along side of single or multiple papillomas
Papillomatosis
• Identified
• Pathologic nipple discharge
• Mammographic density or calcifications
• Associated Risk
• 10% risk of cancer on excision
• 3 to 4X subsequent risk
Complex Sclerosing Lesions
• Radial Scar (Sclerosing
Lesion)
•
•
Sclerotic center with central core
of obliterated ducts, elastin
deposits
Corona of contracted ducts and
lobules with associated
proliferative lesions
• Collangenous
Spherulosis
• Hyperplastic epithelium forms
glands and acellular
spherules
• Less association with cancer
Radial Sclerosing Lesion
Identified
• As a mammographically detected spiculated mass
• More commonly identified in specimens of women with breast
cancer
• Multiple lesions in one breast not uncommon
• Age over 30 and under 60
• Associated Risk
• Risk is the chance of it being a cancer on excision vs RSL
• Risk is the associated lesions the most common being LCIS
LCIS (Lobular Carcinoma In situ)
• Histology
Always multiple ducts
Origin from TDLU
Signet-ring cells may be present
Non-palpable/ no mass
50-75% of one duct involved
Neoplastic cells with scant
cytoplasm and small, round,
bland, diploid nuclei in Type A
or classical LCIS
LCIS (Lobular Carcinoma In situ)
Identified
• Coincidentally in biopsy for proliferative lesion causing mass or
mammographic abnormality
• On needle biopsy of calcifications of associated sclerosing
adenosis or benign calcs (LCIS rarely forms calcifications) It is
not mammographically detectable
• Associated Risk
• 50% risk of LCIS in contralateral breast
• RR 8X and absolute 17% at 15 years (ref: Page Human Pathol
1991; 22:1232-1239
Pleomorphic LCIS
• Histology
Type B LCIS The cells are more
varied with hyperdiploid DNA
with more abundant cytoplasm
Difficult to differentiate b/w DCIS
with intralobular spread
Intracytoplasmic Mucin favors
diagnosis of LCIS mucin stain
may be helpful) and Signet
rings are more characteristic of
LCIS thann DCIS
Pleomorphic LCIS
Identified
• Coincidentally in biopsy for proliferative lesion causing mass or
mammographic abnormality
• On needle biopsy of calcifications of associated sclerosing
adenosis or benign calcs (LCIS rarely forms calcifications) It is
not mammographically detectable
• Associated Risk
• Maybe difficult to differentiate from DCIS
• 50% risk of LCIS in contralateral breast
• RR 8X and absolute 17% at 15 years (ref: Page Human Pathol
1991; 22:1232-1239
ALH (Atypical Lobular Hyperplasia)
• Histology
• Same features as LCIS
• Not suffieciently developed
• Qualitative and quantitative
factors distinguish from
LCIS (< 50 to 75% of one
lobule)
ALH (Atypical Lobular Hyperplasia)
Identified
• Coincidentally in biopsy for proliferative lesion
causing mass or mammographic abnormality
• On needle biopsy of calcifications of associated
sclerosing adenosis or benign calcs (rarely forms
calcifications)
• It is not mammographically detectable
• Associated Risk
ALH is considered a pre-malignant lesion
It is associated with an increased risk of BILATERAL
breast cancer 4.5-5 X more than average risk
ADH (Atypical Ductal Hyperplasia)
• Histology
Fills some but not all
criteria of DCIS
About 2 mm
Distinct cell borders,
increased nuc/cyto ratio,
nuclear enlargement,
irregular chromatin or
nucleoli
Changes associated with
proliferation.
ADH (Atypical Ductal Hyperplasia)
Identified
• Incidentally on biopsy for benign lesion
• On stereotactic biopsy of mammographic abnormality (usually
indeterminant calcs)
Associated Risk
ADH is considered a pre-malignant lesion
It is associated with an increased risk of BILATERAL breast
cancer 4.5-5 X more than average risk

Management: Prevention
Multiple national trials have looked at chemoprevention for
risk reduction
Tamoxifen was found to be preventative when the
contralateral breast cancer risk was halved in patients
receiving Tamoxifen as treatment
Breast Cancer Prevention Trial
(BCPT or NSABP P-1)
• 13,338 high-risk women randomized to daily
tamoxifen vs. placebo for 5 years
Enrollment criteria:
• 60 years of age or older, or
• 35-59 years old with 5-year predicted risk for breast
cancer of at least 1.66%, or
• a history of atypical hyperplasia or lobular carcinoma
in situ

Breast Cancer Prevention Trial
(BCPT or NSABP P-1)
Results:
• Tamoxifen reduced the risk of invasive breast cancer by
49% (89 vs. 175).
• Greatest risk reduction (86%) was in women with
atypical ductal hyperplasia (ADH).
• Tamoxifen increased the rate of endometrial cancer
(36 vs. 15), stroke (38 vs. 24), pulmonary embolism
(18 vs. 6), and deep-vein thrombosis (35 vs. 22).

Why Not Just Treat All High-Risk
Women With Tamoxifen?
• Less than 5% of high-risk women elect to take tamoxifen when
offered.1
• Tamoxifen has some serious side effects (particularly for

Follow up of High Risk Lesions
• Is the lesion in a high risk patient?
ACS definition of very high risk
• Documented deleterious gene mutation in patient
• Gene mutation in family/ patient untested
• Therapeutic radiation to the chest (b/w age10 and 30)
• Lifetime risk of 20 to 25%
• Li-Fraumeni, Cowden, or Bannayan-Riley-Ruvalcaba
syndromes
• ADH or LCIS AND positive family history
High Risk
•
•
•
•
•
2 or more 1st degree relatives at young age
Prior personal history of breast cancer
Extremely dense breasts

• Benefits
• No ionizing radiation
• Dense breasts do not interfere
• High sensitivity
• Limitations
• Expensive
• ? Lower specificity
MRI
• Internatioanl Breast Consortium in 2004 showed that
12% of cancers detected by mammogram or CBE were
not detected by MRI (lack of neoangiogenesis)
• MRI as an adjunct to mammography and BE and that a
neg MRI does not overrule a palpable or mammographic
finding just as a negative imaging workup does not
negate the need to biopsy a palpable finding.

Society Breast Cancer Advisory Group)
ABSTRACT New evidence on breast Magnetic Resonance Imaging (MRI) screening has
become available since the American Cancer Society (ACS) last issued guidelines for the early
detection of breast cancer in 2003. A guideline panel has reviewed this evidence and developed
new recommendations for women at different defined levels of risk. Screening MRI is recommended
for women with an approximately 20–25% or greater lifetime risk of breast cancer,
including women with a strong family history of breast or ovarian cancer and women who were
treated for Hodgkin disease. There are several risk subgroups for which the available data are
insufficient to recommend for or against screening, including women with a personal history of
breast cancer, carcinoma in situ, atypical hyperplasia, and extremely dense breasts onmammography.
Diagnostic uses of MRI were not considered to be within the scope of this review.

Literature related to breast MRI screening published between
September 2002 and July 2006 was identified using
MEDLINE (National Library of Medicine), bibliographies of
identified articles, and unpublished manuscripts.
Expert panel members reviewed and discussed data during a
series of conference calls and a working meeting in
August, 2006. When evidence was insufficient
or lacking, the final recommendations incorporated
the expert opinions of the panel members.
