title: Placental evidence of cytomegalovirus infection of the fetus and neonate.
abstract: Nine cases of congenital cytomegalovirus infection were diagnosed at Brigham and Women's Hospital in Boston from September 1977 through July 1982. The majority of infected fetuses and newborn infants had intrauterine growth retardation, congenital malformations, microcephaly, or hydrops fetalis. In four cases, cytomegalovirus was recovered from placentas. Eight placentas were examined morphologically. Varying degrees of chronic villitis were noted in all. The most frequent lesion, found in six cases, was focal villous inflammation with mononuclear cell infiltrates. Lymphocytes predominated in this reaction. In three cases, however, the villi were also intensely infiltrated by plasma cells. Typical cytomegalic inclusion bodies were noted in these three placentas. The fetus and infants in whose placentas the plasmacytic villitis and inclusion bodies were discovered displayed the most severe manifestations of cytomegalovirus infection.
