: The uterus removed at 20-week pregnancy in a female with grave lupus erythematosus complicated with an antenatal fetus death was studied. Signs of arthrosis typical for late pregnancy were found in the spiral arteries of basal decidua in the zone of contact between mother tissue and trophoblast. Fetal death was due to massive thrombosis.
