Two cases of retroperitoneal teratoma, one in a 8 months old female infant and another in a 3 months old female infant, with the chief complaint of abdominal mass, were reported. Both cases were successfully treated by total extirpation. The histological examinations revealed benign teratoma and up to the present, there has been no sign of recurrence.
The domestic literatures were reviewed and 59 cases of retroperitoneal teratoma in infants were tabulated.
