Q

Name the 4 most common diagnoses for breast lumps.

A
  1. Benign cystic change (fibrocystic change): benign collection of fibrous tissue +/- cysts
  2. Fibroadenoma: benign breast tumour made up of stromal and epithelial tissue
  3. Cyst: benign fluid-filled sac
  4. Carcinoma
2
Q

What type of breast lumps are common in lactating women?

A
  • abscess
  • galactocoele: firm mass caused by obstruction of lactiferous duct which becomes distended with milk and epithelial cells
  • mastitis: usually caused by skin commensals like S. aureus or S. epidermis
3
Q

What is the likely diagnosis if the lump appeared very fast? Slow?

A

Fast: abscess or cyst
Slow: fibroadenoma or carcinoma

4
Q

Trauma (e.g. injury, cyst aspiration) predisposes to what type of breast lump?

A

fat necrosis

5
Q

If the lump is painful, what diagnoses are more likely?

A
  • benign cystic change
  • acute mastitis
  • abscesses
  • cysts
6
Q

What is the likely diagnosis if a lady presents with discharge that is:

  • bloody
  • serous/serosanguinous
  • green/brown/yellow
  • milky?
A
  • bloody: carcinoma
  • serous: intraductal papilloma
  • green/brown/yellow: periductal mastitis
  • milky: galactocoele
7
Q

Lump feels:

  • irregular surface
  • indistinct contours
  • mixed consistency
  • immobile
  • not fixed

Diagnosis?

A

benign cystic change

8
Q

Lump feels:

  • smooth surface
  • distinct contours
  • firm-lax consistency
  • immobile
  • not fixed

Diagnosis?

A

solitary cyst

9
Q

Lump feels:

  • irregular surface
  • indistinct contours
  • hard consistency
  • immobile
  • maybe fixed

Diagnosis?

A

carcinoma

10
Q

Lump feels:

  • smooth surface
  • distinct contours
  • rubbery consistency
  • mobile
  • not fixed

Diagnosis?

A

fibroadenoma (breast mouse)

11
Q

A pt presents with a breast lump. How would you investigate?

A

Triple assessment:

  1. clinical examination
  2. radiological examination
    - USS if <35yrs (breast tissue too dense for mammography)
    - 2-view mammogram (+/- USS) if >35yrs
  3. fine needle aspiration or core biopsy: FNA provides info on cell type/dysplasia whilst core biopsy also informs on local architecture
12
Q

How would you manage a pt with fibroadenoma?

A
  1. Conservative: reassure Pt maj. of fibroadenomas resolve over several years and pose no increased risk of malignancy.
  2. Excisional biopsy: if pt preference, lump increasing in size, lump causing discomfort.
13
Q

How should a pt with a breast abscess be treated?

A
  • antibiotics

- surgical drainage or aspiration

14
Q

Suggest possible causes for gynaecomastia.

A
  1. physiological/hormonal fluctuations
  2. liver disease
  3. drugs, e.g. cimetidine, spironolactone, phenothiazines, finasteride, anabolic steroids
  4. primary testicular failure, e.g. anorchia, bilateral cryptorchidism
  5. acquired testicular failure, e.g. mumps orchitis
  6. secondary testicular failure, e.g. panhypopituitarism
  7. endocrine tumours, E.g. testicle, adrenal, pituitard
  8. non-endocrine tumours, e.g. bronchial carcinoma
