  • Papillary, gland-like or cribriform patterns, lined by epithelial cells with mild to moderate nuclear pleomorphism, loss of polarity, stratification, crowding, hyperchromasia and scattered mitotic figures; no invasion
  • May be associated with severe inflammation and scarring mimicking adenocarcinoma
