Complex sclerosing lesion
Diagnosis in short

Complex sclerosing lesion of breast. H&E stain. (WC)

Synonyms radial scar

LM stellate lesion (low magnification), center of lesion has fibroelastosis (stroma light pink on H&E), scar like stroma with entrapped normal breast ducts and lobules - glands appear to enlarge with distance from center of lesion
LM DDx invasive ductal carcinoma
IHC myoepithelial cells preset (p63 +ve, calponin +ve)
Gross spiculated mass
Site breast

Prognosis benign, increased risk of malignancy
Clin. DDx breast cancer
Treatment excision

Complex sclerosing lesion (abbreviated CSL), also radial scar, is a benign lesion of the breast that is associated with an increased risk of subsequent breast cancer.

General

  • The term radial scar is a misnomer. It isn't a scar. It isn't associated with prior trauma or surgery.[1]
  • May appear malignant on imaging.[2]
  • Associated with subsequent elevated risk of breast cancer.[3]
  • Management - usu. surgical excision.[5]

Gross

  • Spiculated mass.
  • Usually small - 3-7 mm.

Microscopic

Features:[5][6]

  • Stellate appearance (low magnification).
  • Center of lesion has "fibroelastosis" - stroma light pink (on H&E) - key feature.
    • Scar like stroma with entrapped normal breast ducts and lobules.
    • Glands appear to enlarge with distance from center of lesion.

Notes:

  • Histomorphologic appearance may mimic a desmoplastic reaction of the stroma - leading to a misdiagnosis of malignancy.
  • "Hyaline - pink stuff on H&E - is the key."

IHC

Features:

  • p63 +ve.
  • Calponin +ve.

Note:

  • HMWK +ve/-ve. (???)
