Introduction: To determine perinatal complications and pregnancy outcome in 12 women with chorioangioma of placenta. Study design: During the period between January 1986 and December 1997, 12 women with histologic diagnosis of chorioangioma of placenta who delivered in our institution were studied. Case-control study was designed. Sixty women with histologic examination of the placenta without chorioangioma were randomly identified as control group matched for maternal age and parity. Statistical analyses included t-test, Chi-square test and Fisher's exact test when appropriate. Results: Nine cases (75%) were diagnosed postnatal. The mean gestational age was significantly lower and preterm delivery rate was significantly higher among the chorioangioma group (34 vs. 38.8 weeks P<0.0001; 66% vs. 10%; P<0.001 respectively). Conclusions: Chorioangioma of the placenta, in a high risk population, although small, is associated with significantly higher risk for preterm delivery. This emphasizes the need for pathologic examination of all placentas of patients with preterm delivery.
