Report of fourteen cases of nonimmune hydrops fetalis in association with hemorrhagic endovasculitis of the placenta

Case 23-1997

“…The most common microscopic lesion of the placenta that is associated with nonimmune fetal hydrops is a hemorrhagic endovasculitis, which can cause death in utero. 41 In this case, the fetus had no detectable placental or umbilical-cord masses, but microscopic lesions of the placenta cannot be ruled out.…”

These same lesions are now described as haemorrhagic endovasculitis within the placenta (Novak et al, 1991). The occurrence of similar lesions within the hydropic fetus has only recently been described (Larroche et al, 1992).…”
