[A clinicopathological analysis of 15 cases with congenital tumors in fetus and newborn].
OBJECTIVE
The incidence rate of congenital tumors in fetuses and neonates and its influence on fetal outcome including development and death were analysed.


METHODS
Both clinical manifestations and pathological data of 15 cases with congenital tumor were analysed retrospectively.


RESULTS
The incidence rate of congenital tumors in fetuses and neonates was 7.7/100,000 with a rate of 0.7% in total perinatal autopsies. The most common tumor was teratoma (46.7%), the next was hemangioma (26.7%). Among 15 cases with congenital tumor, 9 cases (60.0%) were complicated with polyhydroamnios; 11 perinates (73.3%) were born with body weight appropriate for gestational age, 6 perinates (40.0%) were associated with various anomalies which were commonly secondary to the tumors. The common causes responsible for death were malformation, placental impairment due to tumor invasion or tumor grown at a special site.


CONCLUSIONS
The incidence rate of congenital tumors in fetuses and neonates was very low. Because the tumor usually exhibited a local effect, under carefully evaluating the development of neonates, it is promising to get complete cure.
