Sclerosing adenosis of the breast, also sclerosing adenosis, a benign pathology of the breast associated with an increased risk of malignancy.
General
- Can look like ductal carcinoma.
- Derived from sclerosing[1] (hardening) and adenosis (glandular proliferation).
- Think scaring + many glands packed together.
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.
