Cytology description
  • Uniform glandular cells with fenestration or microacini (Acta Cytol 1999;43:110)
  • Bi or tridimensional cellular clusters of cubic or cylindrical glandular cells with vacuolated cytoplasm, also cells with dense cytoplasm and basaloid cells
  • Often has an immature metaplastic pattern (Diagn Cytopathol 2004; 30:57)
  • Also reserve cells with scant cytoplasm and small, round nuclei
  • May have plasma cells or other inflammatory cells
  • May have cytologic atypia (Diagn Cytopathol 1994; 10:326) due to hyperchromatic crowded groups, nuclear enlargement, hyperchromasia
  • Cells may have multiple nucleoli, mitotic figures, apoptotic bodies and focal, watery diathesis (Acta Cytol 2000; 44:661)
