Q

What is fat necrosis ?

A

Acute inflammatory response in the breast leading to ischaemic necrosis of fat lobules.

25
Q

What are the clinical features of fat necrosis ?

A

Asymptomatic or presents as a lump
Solid irregular lump if chronic fibrotic changes

26
Q

What are some investigations for fat necrosis ?

A

Positive traumatic history
Hyper echoic mass on USS

Fibroadenoma
Adenoma
Papilloma
Lipoma
Phyllodes tumour

29
Q

What is a Fibroadenoma ?

A

Common benign growth in the breast
Usually occurs in women of reproductive age
They are proliferations of stromal and epithelial tissue of the ductal lobules.

30
Q

What is found of examination of Fibroadenomas ?

A

Highly mobile lesions that are well defined and rubbery

31
Q

What is an adenoma of the breast ?

A

Benign glandular tumour
Nodular and mimic malignancy

32
Q

What are some differences between being and malignant breast lumps ?

A

Benign - more mobile, smoother borders, single mass
Malignant - craggy, firm and fixed, may have multiple lumps

33
Q

What are some investigations for benign lumps ?

A

Triple assessment - examine, imaging and histology
Reassurance and routine check up

34
Q

What is gynaecomastia ?

A

A condition by which males develop breast tissue due to an imbalanced ratio of oestrogen and androgen activity.

35
Q

What is the pathophysiology of physiological gynaecomastia ?

A

Most commonly occurs in adolescence resulting from delayed testosterone surge relative to oestrogen in puberty.

36
Q

What are some causes of pathological gynaecomastia ?

A

Lack of testosterone - Klinefelter’s syndrome, androgen insensitivity
Increased oestrogen - liver disease, hyperthyroidism and obesity
Medication - digoxin, Spironolactone
Idiopathic

37
Q

What are some clinical features of gynaecomastia ?

A

Insidious onset
Rubbery or firm mass
Starts from under the nipple

38
Q

What investigations should be performed when suspecting gynaecomastia ?

A

Tests are only necessary if the cause is unknown
U&E’s
LFTs
Hormone profile

39
Q

What is given if gynaecomastia to relieve symptoms ?

A

Tamoxifen

40
Q

What are the 2 types of breast carcinoma in situ ?

A

Ductal carcinoma in situ
Lobular carcinoma in situ

41
Q

What is ductal carcinoma in situ ?

A

Malignancy of the ductal tissue of the breast that is contained within the basement membrane.

42
Q

What is seen on mammography in someone with ductal carcinoma in situ ?

A

Suspicious microcalcifications

43
Q

What is the management of ductal carcinoma in situ ?

A

Surgical excision - breast conserving surgery or mastectomy

44
Q

What is lobular carcinoma in situ ?

A

Non-invasive lesion of the secretory lobules of the breast that is contained within the basement membrane.

45
Q

When is lobular carcinoma in situ usually diagnosed ?

A

Incidental finding on biopsy

46
Q

What is the management of lobular carcinoma in situ ?

A

Low grade - monitoring
If the patient has BRCA1 and BRCA2 genes - bilateral prophylactic mastectomy

Can be asymptomatic
Breast and axillary lump
Asymmetry or swelling

50
Q

What are some investigations for breast cancer ?

Focal smaller cancers

53
Q

What is a mastectomy ?

A

Removal of all the tissue of the affected breast along with a significant portion of overlying skin.

54
Q

When are hormonal treatment used in treating breast cancer ?

A

In malignant non-metastatic disease as an adjuvant after surgery

55
Q

How does tamoxifen work ?

A

It acts through blockade of oestrogen receptors and therefore also has a role in prophylaxis of breast cancer

56
Q

What are some complications of tamoxifen ?

A

Risk of VTE
Increases risk of uterine carcinoma

57
Q

How does immunotherapy work ?

A

It is used in patients whose cancer express specific growth factor receptors

58
Q

What is herceptin and what does it target ?

A

It is a monoclonal antibody that targets the human epidermal growth factor receptor ( HER-2 positive malignancies ).
