Case Reports


In this article, we report the histopathologic findings in a placenta from an early second trimester abortion. The placental villi showed prominent scalloping with many intravillous trophoblastic pseudoinclusions and mild trophoblastic hyperplasia, mimicking the morphology of partial hydatidiform mole. The placental karyotype was 46,XY,del(18)(q21). These histopathologic changes have been previously described in numerical chromosomal aberrations like triploidy, tetraploidy, and trisomies, but not in structural chromosomal abnormalities.
