Objective To explore the diagnosis, treatment and prognosis of testicular benign tumors in children.Methods The clinical data of 26 boys ( aged between 17 days to 12 years and average age was 2.5 years) with testicular benign tumors treated in our center between January 2008 and December 2015 were retrospectively analyzed.The tumors were on the left side in 17 cases, on the right side in 9 cases. Twenty patients presented with painless scrotal mass.3 with cryptorchidism, 2 cases with hydrocele, and 1 case with varicocele.These boys underwent ultrasound or CT examination, results the enlarged tests with space-occupying lesions in 20 cases,3 cases were presented as scrotal empty,3 cases were showed as cystic masses.Twenty-four boys had taken tumor marker detection,which including 3 cases of AFP rised, 2 cases of Neuron-specific enolase slightly higher, 1 case of Ferritin increased.26 patients were performed surgical treatment, 23 cases have taken testicular tumor resection, and 3 cases underwent orchiectomy because of abnormal morphology, according to the intraoperative findings and quick frozen pathological examination results.Results Postoperative pathological diagnosis showed of maturity teratoma in 14 cases, not maturity teratoma in 3 cases, gonadoblastoma in 3 cases, interstitial cell tumor in 2 cases, epidermoid cyst in 2 cases, fibrocellular tumor and testicular inflammatory granuloma in 1 case respectively.The 23 cases were followed up for 3-70 months.All respondents children were alive, and no complications were found such as residual tumor atrophy or tumor recurrence and metastasis.Conclusions Early diagnosis and treatment is the key to obtaining a good effect of testicular tumors. Detailed specialist examination, preoperative ultrasound, CT and determination of tumor markers are important ways to diagnose testicular cancer; rapid intraoperative frozen check may manifest nature of the tumors.For pediatric testicular benign tumor, testis-sparing surgery should be considered.
