Definition / general
  • Extensive proliferation of basal cells involving > 100 small crowded acini (per section) forming a nodule (Hum Pathol 2005;36:480)
  • When forming a nodule, it has been termed basal cell adenoma or adenoid basal cell tumor
Microscopic (histologic) description
  • Almost always mild to moderate nuclear atypia (including prominent nucleoli and nuclear enlargement), intraluminal amorphic secretions
  • Also intracytoplasmic hyaline globules (53%), microcalcifications (40%), no crystalloids
  • See basal cell hyperplasia for images
