Cystitis glandularis is an uncommon type of inflammatory process that afflicts the urinary bladder (cystitis).

Cystitis cystica et glandularis and pyelitis cystica et glandularis redirect to here.

General

  • Benign.[1]
  • Can be thought of as cystitis cystica with mucin-secreting cells lining the cystic spaces.[2]
  • When seen in conjunction with cystitis cystica it is called cystitis cystica et glandularis.

Note:

  • There are case reports of urethritis glandularis - the same lesion in the urethra.[3][4]

Microscopic

Features:[5]

  • Nests of urothelium within the lamina propria with cyst formation, i.e. lumens are present.
  • Cyst lining cells are cuboidal and/or columnar epithelium.
    • Produce mucin.
  • +/-Goblet cells, i.e. intestinal metaplasia.[2]

Note:

  • Nests should not extend into the muscularis propria.
