'''Cystitis cystica''' is a common inflammatory process of the [[urinary bladder]] with cyst formation. | |||
===General=== | |||
*Benign. | |||
*Can be thought of as [[von Brunn nests]] with cystic change.<ref name=Ref_WMSP304>{{Ref WMSP|304}}</ref> | |||
*Called ''[[ureteritis cystica]]'' if it happens in a [[ureter]]. | |||
**There is also a ''urethritis cystica'' - seen in the [[urethra]].<ref name=pmid22397870>{{Cite journal | last1 = Conces | first1 = MR. | last2 = Williamson | first2 = SR. | last3 = Montironi | first3 = R. | last4 = Lopez-Beltran | first4 = A. | last5 = Scarpelli | first5 = M. | last6 = Cheng | first6 = L. | title = Urethral caruncle: clinicopathologic features of 41 cases. | journal = Hum Pathol | volume = 43 | issue = 9 | pages = 1400-4 | month = Sep | year = 2012 | doi = 10.1016/j.humpath.2011.10.015 | PMID = 22397870 }}</ref> | |||

*Nests of urothelium within the lamina propria with cyst formation, i.e. lumens are present. | |||
Note: | |||
*Nests should '''not''' extend into the muscularis propria. | |||

====Micro==== | |||
The sections show a small fragment of urothelial mucosa with small urothelial nests that are focally cystic. The nests are well-circumscribed and approximately of equal size. Adjacent to the nests is a small cluster of bland appearing lymphocytes. | |||
No exophytic component is identified. No papillary structures are apparent. The cytomorphology of the urothelium is bland and no mitotic activity is readily apparent. | |||
