placenta creta

Placenta creta (placenta accreta , placenta increta , or placenta percreta ) is a clinically symptomatic condition, usually diagnosed histologically on hysterectomy specimens.

At a minimum, focal absence of decidua is the histological finding for this condition; however, excessive amounts of extravillous trophoblasts were recently documented on hysterectomy specimens.

The histological finding of basal plate myometrial fibers (BPMF) without intervening decidua in spontaneously delivered placentas is called "occult placenta accreta" (OPA), and is not infrequent, even in clinically asymptomatic cases. (17638431)
