Micro Description
  • Multiple secondary lumens having round, regular spaces with sharp borders that appear to be made from "cookie-cutters," usually low grade
  • Nuclear palisading around the lumens (the long axes of the nuclei are perpendicular to the lumens
  • May have small, regular fenestrations (Latin, the arrangement of windows in a building), giving a sieve like appearance
  • Nuclei are usually small and uniform, equidistant from each other; usually no necrosis
  • Trabecular bars: rigid rows of cells with long axes perpendicular or at least not parallel to long axis of the bar (not just partial detachments of duct lining)
  • Roman bridges: curvilinear trabecular bars connecting two portions of the epithelial lining

Differential Diagnosis
  • Adenoid cystic carcinoma: true glandular lumina lined by ductal epithelium and eosinophilic "cylinders" with basement membrane material lined by basal cells; usually ER- and PR- CD117+ luminal cells, p63+, calponin and smooth muscle actin negative
  • Atypical ductal hyperplasia: cells are pleomorphic and occupy less than 2 duct spaces
  • Collagenous spherulosis: intraductal lumina of hyaline, acellular eosinophilic spherules lined by myoepithelial cells
