===Gross===
*Usually not seen on gross pathology.
 
===Microscopic===
Features:
*Increased blood vessels in the terminal villi.

***The definition suffers from [[IPFitis]].
*Lesion ''not'' well circumscribed.
*Villi tend to be larger and have centrally placed blood vessels.<ref>E. Latta. 26 July 2011.</ref>
 
Notes:
*Normal villi have up to five vascular channels.<ref name=pmid11520290>{{Cite journal  | last1 = De La Ossa | first1 = MM. | last2 = Cabello-Inchausti | first2 = B. | last3 = Robinson | first3 = MJ. | title = Placental chorangiosis. | journal = Arch Pathol Lab Med | volume = 125 | issue = 9 | pages = 1258 | month = Sep | year = 2001 | doi = 10.1043/0003-9985(2001)1251258:PC2.0.CO;2 | PMID = 11520290 | url=http://www.archivesofpathology.org/doi/full/10.1043/0003-9985%282001%29125%3C1258:PC%3E2.0.CO;2}}</ref>
