Objective To analyze the clinical features and treatment of ovarian cysts in children.Methods The medical records of 107 children younger than 14 years old with a diagnosis of ovarian cysts were reviewed.Results 34 cases were on the left side,67 on the right and 6 on both sides.There were 22 cases found in neonates,8 cases in infants,24 cases at school age,28 cases in prepuberty,and 25 cases at puberty.The symptoms were related to age.Only 1 case had mild abnormality in the pituitary gland,and 63.8 ％ of patients had elevated serum E2 with age.73 cases accepted surgical intervention,13 of them were revealed as true ovarian tumor.71.2％ of patients who received surgery had their ovaries preserved(36 cases were done by laparoscopy,and 37 were done by laparotomy).3 tumor cases recurred.34 cases were treated conservatively,86％ of them were discharged during short follow up.Conclusions Ovarian cysts can occur in any age with high incidence,with different symptoms.It is essential to differentiate from ovarian tumor.We suggest conservative treatment for ovarian cyst,and surgery is reserved for those with increase in size or twisted.Laparoscopy is a minimal invasive procedure,enucleation and preservation of ovary tissue is a rule for intervention.Relapse of functional cyst is rare.
