| Sclerosing adenosis of the breast | |
|---|---|
| Diagnosis in short | |
|
| |
| LM | increased numbers of small breast acini with collapsed or slit-like lumens, fibrosis (scleroses) surrounds the acini |
| LM DDx | low-grade ductal carcinoma, tubular adenoma of the breast, adenomyoepithelioma, breast adenosis |
| Site | breast |
|

| Prevalence | common |
| Prognosis | benign, increased risk of breast cancer |
Sclerosing adenosis of the breast, also sclerosing adenosis, a benign pathology of the breast associated with an increased risk of malignancy.
General
- Can be scary... can look like ductal carcinoma.
- Derived from sclerosing[1] (hardening) and adenosis (glandular enlargement).
- Think scaring + lotsa glands and you're pretty close.
- Management: follow-up, no further treatment.[2]
Microscopic
Features:
- Acini are smaller than usual and there are more of them.
- Acini often slit-like.
- Fibrosis (scleroses) - pink on H&E surrounds the acini.
- Can mimic a desmoplastic reaction.
Notes:
- The acini should:
- Be in lobular arrangements, i.e. in groups (benign appearance at low power) - key feature.
- Have two cell layers like well-behaved breast glands do.
DDx:
- Low-grade ductal carcinoma.
- Tubular adenoma of the breast.
- Adenomyoepithelioma.[3]
- Breast adenosis - should have visble lumens.
