Drawing

Micro Description
  • The lumen of the duct is filled by small to medium, uniform polygonal cells
  • May produce a microacinar or rosette-like pattern
  • Cells are larger than LCIS but smaller and more uniform than comedocarcinoma
  • Cytoplasm can show a spectrum of changes including clear, granular and apocrine change
  • Comedonecrosis is usually absent but small foci of necrosis may be present
  • Usually low or intermediate grade (Anal Quant Cytol Histol 2001;23:418)
