21
Q

Mangaemnt of breast cysts

Study These Flashcards
A
  • Aspirated, those which are blood stained or persistently refill should be biopsied or excised
22
Q

Common cause of fat necrosis

Study These Flashcards
A
  • Localised trauma, radiotherapy or surgery, with an inflammatory reaction resulting in fibrosis and necrosis (death) of the fat tissue. It does not increase the risk of breast cancer.
23
Q

Presentation of fat necrosis

Study These Flashcards
A

Painless
Firm
Irregular
Fixed in local structures
There may be skin dimpling or nipple inversion

24
Q

what is mammory duct ectasia

Study These Flashcards
A

dilation of the large ducts in the breast

25
Presentation of mammary duct ectasia
Nipple discharge (cheese like/brown green) Tenderness or pain Nipple retraction (slit like) or inversion A breast lump (pressure on the lump may produce nipple discharge)
26
Finding on mammogram in mammory duct ectasia
Microcalcifications
27
what is an intraductal papilloma
Local areas of epithelial proliferation in large mammary ducts = warty lesion
28
Possible presentation of papilloma
Nipple discharge (clear or blood-stained) Tenderness or pain A palpable lump
29
Management of papilloma
Surgical excision
30
Presentation of mastitis
painful, tender, red hot breast fever, and general malaise may be present
31
management of mastitis
- Continue to breastfeed, analgesia ad warm compress for 24 hrs 10 -14 days oral flucloxacillin (as usually staph aureus)
32
Complication of intreated mastitis
Breast abscess
33
what suggests development of breast abscess
Swollen, fluctuant tender lump
34
Management of non lactational mastitis
- Co-amoxiclav - Erythromycin/clarithromycin (macrolides) plus metronidazole (to cover anaerobes)
35
Management of breast abscess
- Referral to the on-call surgical team in the hospital for management -Antibiotics - Ultrasound (confirm the diagnosis and exclude other pathology) - Drainage (needle aspiration or surgical incision and drainage) - Microscopy, culture and sensitivities of the drained fluid
36
4 causes of hyperprolactinaemia
1. Idiopathic 2. Prolactinomas 3. Endo : hypothyroid, PCOS 4. Medications : dopamine agonists
37
4 symptoms of hyperprolactinaemia and why
Suppresses GnRH from hypothalamus = low LH, FHS 1 ED 2. Reduced libido 3. Gynaecomastia 4. Amennorhoea
38
Association with prolactinoma
Multiple endocrine neoplasia type 1
39
Key bloods to do for galactorrhoea
Serum prolactin Renal profile (U&Es) Liver function tests (LFTs) Thyroid function tests (TFTs)
40
Management of prolactinoma
- Dopamine agonists (e.g., bromocriptine or cabergoline)
41
Causes of gynaecomastia and why
RAISED OESTROGEN,LOW TESTOSTERONE 1. Raised prolactin (=dopamine antagonists - antipsychotics) 2. Idiopathic 3. Liver cirrhosis 4. Obesity 5. Testicular cancer = leydig cell tumour 6. Hyperthyroid
42
gynaecomastia caused by conditions that reduce testosterone
- Testosterone deficiency in older age - Hypothalamus or pituitary conditions that reduce LH and FSH levels (e.g., tumours, radiotherapy or surgery) - Klinefelter syndrome (XXY sex chromosomes) - Orchitis (inflammation of the testicles, e.g., infection with mumps) - Testicular damage (e.g., secondary to trauma or torsion)
43
Drugs causing gynaecomastia
- Anabolic steroids (raise oestrogen levels) - Antipsychotics (increase prolactin levels) - Digoxin (stimulates oestrogen receptors) - Spironolactone (inhibits testosterone production and blocks testosterone receptors) - Gonadotrophin-releasing hormone (GnRH) agonists (e.g., goserelin used to treat prostate cancer) - Opiates (e.g., illicit heroin use) - Marijuana - Alcohol
44
what is paget's disease of nipple
- Eczematoid change of nipple associated with underlying malignancy
45
Complicationv of axillary node clearance
Lyphoedema causing functional arm impairment
46
what chemotherapy is used for breast cancer that is axilary node positive
FEC-D
47
Key reason for neo-adjuvant chemotherapy
downsize the tumour before surgery and allow breast conserving surgery rather than mastectomy
48
Histological signs of DCIS
Comedo necrosis
49
Histologysign of mucinous carcinoma
Grey, gelatinous surface
