Definition / general
  • More severe cases are called endocervical glandular dysplasia (atypical hyperplasia)
  • In United Kingdom, use terminology of CGIN - cervical glandular intraepithelial neoplasia
  • Not a reproducibly defined entity with a specific cause or outcome
  • Patients with diagnosis based on cervicovaginal smears often have squamous dysplasia (Obstet Gynecol 1992;79:101)
  • Appears to NOT be a precursor to adenocarcinoma in situ (Hum Pathol 2000;31:656)
  • Atypical oxyphilic metaplasia: incidental finding of endocervical glands lined by large cuboidal or polygonal epithelial cells with dense, eosinophilic, focally vacuolated cytoplasm and variable nuclear enlargement, hyperchromatism, multiple lobes or multinucleation; no mitotic activity or stratification; benign behavior (Int J Gynecol Pathol 1997;16:99)
Microscopic (histologic) description
Glandular atypia
  • Glandular cells with hyperchromatic nuclei with only occasional mitotic figures and minimal pseudostratification
  • No cribriform areas, no papillary projections, no crowding, no mitotic figures
  • Alternatively there is marked atypia involving only a single gland
  • Normal N/C ratio
Glandular dysplasia
  • Resembles adenocarcinoma in situ but nuclei are not malignant and have fewer mitotic figures OR malignant involvement of only one gland
