8
Q
A

multiple round masses of varying size in both breasts. masses are very well defined, have a black halo (benign appearance on mammography)

Appearance in keeping with cysts however requires an ultrasound to make a definitive diagnosis

Q
A

Malignant mass

  • irregular shaped, ill defined margins and invades across normal tissue planes indicated by the appearance of surrounding tissue

14
Q

management of patients with normal pre operative axillary assessment

A

benign mass because:

  • rounded shape
  • well defined borders
  • benign tissue tends to push the surrounding tissue out of the way

Q

management of patients with abnormal axillary nodes on ultrasound + confirmed by core biopsy/FNA

A

axillary node clearance

17
Q

what is a sentinel node?

A

the first of the axillary lymph nodes that will collect cancerous cells, if the cancerous breast cells have entered the lymphatic system

18
Q
A

FNAC - normal breast ductal epithelial cells because; uniform in size and appearance, cohesive and contain regular round nuclei

19
Q
A

FNAC - C5: malignant cells from breast carcinoma

  • cells are scattered singly and contain varibaly sized irregular nuclei
  • background contains cell debris (due to karyorrhexis which is breakdown of nuclei)
20
Q
A

Core biopsy - normal breast tissue

21
Q
A

core biopsy - invasive ductal carcinoma

22
Q

advantages of core biopsy over FNAC

A
  • interpretation does not require a highly trained and experienced pathologist
  • can be easier to classify a malignant lesion as invasive or non invasive
  • sample includes more tissue than in FNAC
  • cytology preparations can ascertain receptor status of a cancer
23
Q
A

benign fibroadenoma

benign neoplasm of both the stromal and epithelial cell components of the breast. Well circumscribed, non infiltrative lesion that lacks atypia

24
Q
A

benign fibrocystic changes

(can fluctuate with hormonal changes)

25
Q
A

malignant ductal carcinoma

  • irregular, infiltrative borders that are described as spiculated/star lik eon radiographic images.
26
Q
A

1 - chest wall

2 - pectoralis major

3 - breast lobules

4 - nipple

5 - aerola

6 - milk ducts

7 - fatty tissue

8 - skin/inframammary fold

27
Q

which structure is breast cancer thought to arise from?

A

TDLU = terminal duct lobar unit

28
Q
A

US image of breast that is breastfeeding

  • glandular enlargement
  • engorgement of breast tissue –> echogenecity of breast parenchyma
29
Q
A
  • Smooth 20 mm lump @ 4 o clock in left breast, about 2 cm from left nipple
  • 20 mm mass 12 o clock on contralateral right breast lying 1 cm from nipple
30
Q
A

Pagets disease

31
Q
A

Montgomery tubercles

(sebaceous glands in the aerola around the nipple… are more pronounced during pregnancy)

32
Q
A

USS of solid mass w/ ovoid shape + well defined

fibroadenoma

33
Q
A

multiple popcorn calcification

multiple fibroadenomas that have shrunk and undergone calcification due to post menopause

34
Q
A

multiple round opacities of varying size.

well defined

have “black halo” which is a benign feature on mammography

appearance in keepign with cysts.

35
Q
A

USS showing a well defined rounded mass with a black anechoic fluid centre.

breast cyst.

36
Q

what does this show + next steps in management?

A
  • microcalcification
  • magnification view on mammogram: close up detailed image of small area of breast tissue
