*[[AKA]] ''cervical adenocarcinoma''.
===General===
{{Main|Adenocarcinoma of the uterine cervix}}
*Adenocarcinoma of the cervix is much less common than squamous dysplasia of the cervix/SCC of the cervix.
*Arises from the endocervical glands.
 
===Microscopic===
Features:
*Stromal changes - "[[desmoplastic stroma]]/[[desmoplastic reaction]]".
**Fibrosis/streaming cells.
*Gland fusion.
*Glands too deep -- very fuzzy criterion.
 
Notes:
*AIS changes - similar to [[colon|colonic]] dysplasia.
*AIS may occur together with CIN.
**Not infrequently they (AIS, CIN) occur together - both are due, indirectly, to HPV infection.
*May be difficult to be certain of invasion.
**A feature suggestive of invasion is ''cytoplasmic eosinophilia''.
 
DDx:
*[[Microglandular hyperplasia]] - [[NC ratio]] normal, no nuclear atypia.
*[[Endocervical adenocarcinoma in situ]].
*Metastatic adenocarcinoma.

===IHC===
Features for diagnosis:
*p16 +ve.
*Ki-67 -- high.
 
Uterus vs. cervix:<ref>LAE. 15 January 2009.</ref>
*Cervix (typically): CEA +ve, p16 +ve.
**ER -ve, PR -ve, vimentin -ve.
*Uterus (typically): vimentin +ve, ER +ve, PR +ve.
**CEA -ve, p16 -ve.
