Q

Lactating breast histology?

A

The terminal duct lobular units are conspicuously enlarged, with inapparent interlobular and intralobular stroma.
The individual terminal ducts, now termed acini, show prominent epithelial secretory activity (cytoplasmic vacuolization).
The acinar lumina contain secretory material.

Q

Relationship between FCC and breast cancer?

A

FCC doesn’t increase the risk of getting breast
cancer, but it can make it more difficult to identify potentially cancerous lumps during breast examination and on mammograms.

Q

Fibroadenomas:

  • Arise from?
  • Composition?
  • Features?
  • Clinical presentation?
A
  • Fibroadenomas arise from breast lobules and are composed of fibrous and epithelial tissue.
  • They are well circumscribed and highly mobile, because of the encapsulation and pliability of young breast tissue.
  • Clinically, fibroadenomas are difficult to differentiate from Phyllodes Tumours, which is a distinct pathology.

Q

How to differentiate between fibroadenomas and Phyllode tumours?

A
  • Phyllodes tumours are sarcomas which rapidly enlarge and have variable degrees of malignant potential.
  • They are larger than fibroadenomas and tend to occur in an older age group (15-20 years later).
  • Fibroadenomas appear as a well-defined, smooth, oval- shaped lump, distinctly mobile and easily identified on ultrasound.
  • Young patients (less than 25 years) with clearly benign clinical and imaging findings are usually spared a core biopsy.
  • In older patients we have to rule out occult malignancy / Phyllodes tumour.

Q

Difference between FCC and fibroadenoma?

A

FCC:

  • Most common benign condition of the breast
  • May be painful
  • Needle aspiration demonstrates straw-coloured / green fluid

Fibroadenoma:

  • Benign solid tumour containing glandular and fibrous tissue
  • Typically a painless, well-circumscribed round and mobile mass
  • More biopsy may be recommended
  • Can be followed clinical or surgically excised
20
Q

Presentation of fat necrosis in the breast?

A

Soft, indistict lump that develops a few weeks after a traumatic incident and often in older women with fatty breasts.
On imaging, difficult to distinguish from breast cancer so a core biopsy is needed.

23
Q

What are the two forms of non-invasive precursors?

A

Ductal carcinoma in situ (often unilateral)

24
Q

Features of high-grade (poorly differentiated) DCIS?

A

Breast duct filled with atypical, crowded cells with a high mitotic rate and areas of apoptosis
The lumen of the duct is filled with dead cells, inflammatory cells and fine calcium granules
There is no invasion of cells beyond the duct

25
Q

What is the more common type of invasive carcinoma?

A

“No special type” (75-90%)

Also infiltrating lobular carcinoma (10%)

26
Q

What is Paget’s disease of the nipple?

A

Leads to erosion of the nipple that resembles eczema

Associated with underlying in situ or invasive carcinoma

A
Tumour type
Tumour grade (A)

HER-2 amplification
28
Q

29
Q

What are the screening strategies for breast cancer?

A

What is the commonest cervical squamous neoplasia?
Main etiological factor?
Immune modulation?

A

Commonest cervical cancer that is an invasive tumour of epithelial origin with squamous differentiation

36
Q

Pre-invasive phase of cervical squamous neoplasia, detected by…

A

Cervical cytology via:

  • pap test
  • liquid based cytology (LBC)
  • Large loop excision of transformation zone (LLETZ)
37
Q

Grading of pre-invasive cervical squamous neoplasia?

A

Bethesda classification:
- ‘Low grade squamous intraepithelial
neoplasia’ LSIL versus ‘high grade’ HSIL
- Cervical intraepithelial neoplasia (CIN)
grades 1 to 3 (2 and 3 correspond to HSIL)

38
Q

How does HPV cause cervical cancer?

A

STI –>
• If infection is persistent the virus may incorporate its DNA into the host cell’s genome.
• Once incorporated, the production of viral oncoproteins can go on unchecked, and the host’s genes that suppress tumours (p53 and pRb) can be inactivated.
• Damaged DNA is replicated without being checked and repaired, and malignantly transformed cells proliferate uncontrollably.

39
Q

Screening and intervention strategies for cervical cancer?

A
  • Cytology :Spatula, Cytobrush, Glass slide, Liquid based
  • HPV detection (16, 18, others)
  • Visual inspection with acetic acid or iodine
  • Vaccination!
  • Colposcopy and biopsy
  • Local excision (‘large loop excision’)
  • Cryotherapy
40

Q

Meaning of:

SIL and CIN?

A
SIL= Squamous intraepithelial lesions
CIN= Cervical intraepithelial neoplasia
42
Q

Progression of LSIL to invasive cancer?

A

70% percent of cases of LSIL (CIN 1) regress, 6% progress to HSIL (CIN 2 & 3) and less than 1% become invasive cancer.

43
Q

Progression of HSIL to invasive cancer?

A

Progression of HSIL (CIN 2 & 3) to invasive squamous carcinoma occurs with greater frequency and over a shorter interval, but the exact figures vary with intervening management.
10% to 20% of cases of HSIL (CIN 2 & 3) progress to invasive carcinoma if untreated.
