Breast Flashcards
Fibroadenoma Ep Ax Sxs Mx [2] Prog
Ep: 20-30y/o
Ax: aberration in normal development
Sy/Si: painless, firm highly mobile lump
Mx:
- conservative if <40y/o or biopsy proven dx
- excision if >40y/o, >3cm or increasing size or pt choice
Pro: usually remain unchanged but 1/3 resolve spontaneously
Fibroadenoma
Ix: describe triple assessment and what you may find
Mammogram: well circumscribed oval mass
USS: well circumscribed round or ovoid mass
FNAC then biopsy
Breast cysts Ep Ax [2] Sxs [2] Mx
Ep: perimenopausal women
Ax: unknown but can be part of fibrocystic breast disease with cyclical mastalgia
Sy/Si: fluctuant or solid lump; may be tender or multiple
Mx: aspiration
Breast cysts
Ix: describe triple assessment and what you may find
- USS: anechoic signal, smooth walls, well circumscribed, underlying fat compression leads to halo sign
- FNAC: do cytology if fluid on aspiration bloody (should be straw coloured)
- Biopsy: if residual lump after aspiration
Phyllodes Tumour
Ax
Benign/malignant
Sxs [2]
Ax: fibro epithelial neoplasm; usually benign but can recur post-excision; some malignant but haematogenous metastasis uncommon
Sy/Si: firm lump, size may increase rapidly
Phyllodes Tumour
Ix: describe triple assessment and what you may find
Mx
Ix
• Mammogram: non-specific large oval or lobulated w/ smooth margins, may have radiolucent halo
• USS: non-specific, mimics fibro adenoma
• FNAC then biopsy
Mx: wide local excision or mastectomy in large tumours
Duct Papilloma Ep Ax Classification [2] Sxs [2] Cx
Ep: common, usually perimenopausal but can occur in younger women
Ax:
- benign neoplasm of sub areolar ducts
Categorised as central or peripheral
Sy/Si:
- single or multiple lumps
- with nipple single duct discharge (usually clear but may be bloody)
Cx: risk of later malignancy greater if peripheral
Duct Papilloma
Ix [4]
Mx
Ix: • Mammogram: normal • USS: well defined solid nodule or intra-ductal mass • Galactography: filling defect • FNAC then biopsy
Mx: no mx or surgical excision of duct (microdochectomy)
Fat necrosis Ax [2] Px Sxs What is one important thing in diagnosing fat necrosis
Ax:
- trauma e.g. seatbelt, implant removal
- prior reconstruction
Px:
- fat cell disruption causes inflammation and fibrosis
Sy/Si:
- firm painful lump, associated haematoma
- CANNOT clinically differentiate from carcinoma*
Fat necrosis
Ix [3]
Mx
- Mammogram: irregular spiculated mass area
- USS: hyper-echoic mass with well-defined margins +/- mural nodules
- FNAC then biopsy
Mx: conservative mx once dx proved by biopsy
Duct Ectasia Ep Ax [2] RF Sxs [2]
Ep: post-menopausal
Ax:
- normal chronic inflammatory fibrotic changes
- where ducts widen and shorten during breast involution in later life
RF: smoking
Sy/Si:
- lump
- nipple discharge (usually THICK AND GREEN; may be bloody)
- SYMMETRICAL slit-like nipple retraction
What is Mondor’s disease
Thrombophlebitis of a breast vein
Duct Ectasia
Ix [3]
Mx [2]
• Mammogram: dilated linear branching densities in sub areolar lesion with rod like calcifications
• USS: dilated fluid filled sub areolar ducts with moving debris
• FNAC then biopsy
Mx:
- conservative once dx proved by biopsy
- can do microdochectomy in young or total duct excision in old for excessive discharge
Lipoma Ax Sx Ix [3] Mx
Ax: benign neoplasm of adipose tissue
Sy/Si: lump
Ix: triple assessment
• Mammogram: fat composed lesion in subcutaneous plane with no calcification
• USS: rounded iso-echoic lesion
• FNAC then biopsy
Mx: conservative once dx proved by biopsy (surgical excision may be needed to confirm dx)
Sclerosing adenosis Prog Ax Px [3] Sxs [2] Ix [2] Mx
Prog: no increased malignancy risk Ax: disorder of involution Px: - distortion of distal lobular unit - without hyperplasia (hyperplasia in complex lesions) - radial scars Sy/Si: - breast lump or breast pain Ix: • Mammogram: can mimic carcinoma • FNAC then biopsy ***must be biopsied*** Mx: can be excised
