-lobar

Breast Cancer spreads:

-noninvasive

-noninfiltrating

-in situ- it’s contained

-invasive

-infiltrating

What is this image showing?

breast carcinoma 

What is multicentric?

co-existent in separate quadrants or separated by more than 5cm

What is multifocal?

additional lesions within the same quadrant or within 5cm

What are malignant characteristics?

• irregular shape

• attenuation shadowing hypoechoic or heterogeneous

• taller than wide

• fixed location

• hard/fibrous

What are malignancies of the breast?

• ductal carcinoma in situ

• invasive ductal carcinoma

• lobular carcinoma in situ

• invasive lobular carcinoma

• comedocarcinoma

• juvenile

• papillary carcinoma

• pagets disease

• scirrhous carcinoma

• medullary carcinoma

• colloid carcinoma

• tubular carcinoma

• mucinous

• phyllodes

What indicates that a lesion is malignant

shadowing

What is the most common non-invasive carcinoma?

ductal carcinoma in situ

What is ductal carcinoma in situ also called?

intraductal carcinoma

Ductal carcinoma in situ is

cancer cells present in the ducts but have not spread

its contained

What kind of prognosis does DCIS have?

very good because they have not spread

What is this image showing?

ductal carcinoma in situ

Lobular Carcinoma in Situ:

-not necessarily considered malignant

-very low malignant potential

-precancerous growth that occurs in the lobules  

What is this image showing?

LCIS

LCIS doesn’t

doesn’t spread, don’t have treatment just follow up to see that it hasn’t grown

What is the most common invasive lesion?

invasive ductal carcinoma 80%

IDC:

begin in ducts but spread to surrounding fatty tissue

-blood and lymph nodes

IDC happens at

peak at age 50

What are the sonographic features of IDC?

-ill defined mass

-hypoechoic  

What is this image showing?

intraductal carcinoma

What is the 2nd most common invasive lesion?

invasive lobular carcinoma 10-15%

Invasive Lobular Carcinoma is often?

bilateral

-multicentric/multifocal

What are these images showing?

invasive lobular carcinoma

Medullary clinical signs and sono features:

solid

rounded

taller than wide

Medullary prognosis is?

good

What is this image showing?

medullary carcinoma

Papillary:

-arises from intraductal papilloma

-earliest sign is bloody nipple discharge

Comedocarcinoma:

-intraductal, solid

-ducts filled with yellow paste like material

What arises retroareolar and grows toward the nipple?

Paget’s disease

Paget’s Disease has a?

rash like appearance

Paget’s Disease is relatively

rare 2.5% of all cancers

What is this image showing?

pagets disease

What is inflammatory breast cancer?

-rare but aggressive

-cancer cells block lymph vessels of the skin

can do skin biopsy because it is superficial

What is the distinct appearance of an inflammatory breast disease?

peau d’orange breast

What is this image showing?
