Histo buzzwords Flashcards
Mastitis
High neutrophils
Breast abscess
Aspirate + culture
Incision + drainage + IV abx (flucloxacillin)
Duct ectasia
Greeny brown discharge
Duct dilatation w/ proteinaceous materials inside ducts + macrophages
Fat necrosis
Damaged fat lobules w/ empty fat spaces
Fibroadenoma
Most COMMON cause of mobile lump in young women
Firm mobile + painless
Stromal proliferation
Phyloides tumour
‘leaf like’ fronds (projections) / ‘artichoke’ appearance
‘malignant fibroadenoma’ - but actually pre-malignant (just more malignant than fibroadenoma)
Fibrocystic disease
Fibrocyst = fluid filled
Size varies w/ periods
Intraductal papilloma
red discharge (bloody)
Dilated duct w/ papillary mass
Radial scar
Mimics breast cancer (but is not cancer) - centrofibrous stellate area
Gynaecomastia
‘Finger-like’ projections
Breast cancers - meaning of cytopathology:
1. 4
2. 5a
3. 5b
- 4 - suspicious of malignancy
- 5a - carcinoma in situ
- 5b - invasive carcinoma
Invasive ductal carcinoma (renamed to no special type -..-)
Most COMMON breast cancer
Large pleomorphic cells
(any breast cancer that can’t be categorised falls into this category - i.e. no specific features)
Invasive lobular
Indian file (single file)
E-cadherin loss
Invasive tubular
Elongated tubules
Invasive mucinous
Empty spaces w/ mucin
Ductal carcinoma in situ
Microcalcifications + necrosis
Lobular carcinoma in situ
NO microcalcifications OR necrosis
Nottingham grading system (used to grade breast cancer) is composed of:
- tubule formation
- nuclear pleomorphisms
- mitotic activity
Prognosis is dependent on…
BONUS: Mx
- Axillary lymph node status
- Oestrogen + progesterone receptor positive = good prognosis
- HER positive = poor prognosis
BONUS: MX -
ER +ve = Tamoxifen (CI: fluoxetine, post-menopausal)
Instead give anastrazole for post-menopausal
HER +ve = Herceptin (AKA trastuzumab)
Basal cell carcinoma of the breast
Triple negative for all receptors (oestrogen, progesterone, HER)
Lymphocytic infiltrate
Test for: basal cytokeratins
Gynae:
1. complication of PID?
2. Endometriosis - where/what are chocolate cysts
3. Fibroids - what type of muscle cell?
4. What type of epithelium is involved in VIN?
5. What proteins do HPV 16 + 18 affect?
- Fitz-Hugh-Curtis
- Endometriomas, typically found on ovaries
- Bundles of smooth muscle cell
- Squamous epithelium (squamous carcinoma AKA primary vulval carcinoma = MOST COMMON type of vulval carcinoma)
- 16 encodes for E6 (inactivates p53); 18 encodes for E7 (inactivated retinoblastoma)
Follicular cyst (ovarian)
regress after several menstrual cycles
only found in pre-menopausal women
