Spontaneous expulsion of decidualized pseudopolyps in pregnant women with uterine malformation

Two cases concerning expulsion of decidualized polyps in early pregnancy associated with uterine malformation are described. The authors discuss the differential diagnosis between the expulsion of cervical polyps during pregnancy and the ectopic pregnancy associated with polyposis. They suggest that a spontaneous expulsion of polyps or pseudopolyps during early pregnancy may be a sign of the presence of uterine malformation.
