'''Chorangioma''' is an uncommon pathology of the [[placenta]] that is similar to a [[hemangioma]].


==General==
*[[Hamartoma]]-like growth in the placenta consisting of [[blood vessel]]s.<ref name=pmid20594143>{{cite journal |author=Amer HZ, Heller DS |title=Chorangioma and related vascular lesions of the placenta--a review |journal=Fetal Pediatr Pathol |volume=29 |issue=4 |pages=199–206 |year=2010 |pmid=20594143 |doi=10.3109/15513815.2010.487009 |url=}}</ref>
Epidemiology:
*Often benign/insignificant; large lesions (>4 cm<ref name=pmid20594143>{{cite journal |author=Amer HZ, Heller DS |title=Chorangioma and related vascular lesions of the placenta--a review |journal=Fetal Pediatr Pathol |volume=29 |issue=4 |pages=199–206 |year=2010 |pmid=20594143 |doi=10.3109/15513815.2010.487009 |url=}}</ref> or >5 cm<ref name=pmid21234259>{{cite journal |author=Lež C, Fures R, Hrgovic Z, Belina S, Fajdic J, Münstedt K |title=Chorangioma placentae |journal=Rare Tumors |volume=2 |issue=4 |pages=e67 |year=2010 |pmid=21234259 |pmc=3019602 |doi=10.4081/rt.2010.e67 |url=}}</ref>) or multiple lesions are significant.
*May be association with:
**Fetal maternal haemorrhage.
**[[Fetal hydrops]].
**[[IUGR]].
*Incidence: ~1 in 100 placentas.<ref name=pmid20594143/>
==Gross==
*White lesions.
**Occasionally red lesions.
==Microscopic==
Features:<ref name=pmid20594143/>
*Mass of capillaries - '''key feature'''.
*+/-High cellularity.
*+/-Degenerative changes.
Notes:
*Must be differentiated from [[chorangiomatosis]] (associated with preeclampsia & IUGR) and chorangiosis (assoc. with maternal [[diabetes mellitus]]).<ref name=pmid20594143/>
