Placental lesions in a case of DiGeorge sequence.
This work describes some placental alterations found in a partial form of DiGeorge sequence, namely, hypoplasia of a cord artery with internal calcification of an extensive endoluminal thrombosis, and widespread calcification of microthrombi in the arteries of the second and third order villous branches. Hypoplasia of a cord artery is a relatively rare event, and is also associated with malformations of the gastroenteric and cardiovascular system, as sometimes described in the DiGeorge sequence. Interesting placental alterations are reported and their likely physiopathologic basis and pathogenic correlation discussed in order to give a better and more comprehensive picture of the DiGeorge sequence in which the correlated placental alterations are not sufficiently known.
