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.

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.
