Testicular tumors in children and adolescents

ObjectiveTo analyze the spectrum of testicular tumors in children in an unselected population-based series, as well as the results of testis-preserving surgery.Patients and methodsOur hospital database was analyzed for operations for testicular tumors from 1981 to 2006. The clinical data and findings during follow up (4.7 years) were recorded.ResultsThirty-four patients were operated on because of testicular tumors. In 23 (68%) the tumor was benign: benign teratoma (16), Leydig-cell tumor (2), epidermoid cyst (2), Sertoli-cell tumor (1), cystic dyplasia (1), intratesticular focal fibrosis (1). Eleven patients (32%) had a malignant tumor: yolk-sac tumor (6), embryonal carcinoma (5). Twenty out of the 26 (77%) prepubertal boys had a benign tumor in contrast to only three of the eight (38%) adolescent males (P = 0.079). Testis-preserving surgery was performed in 10 patients. In eight, the tumor was curatively excised and remaining testis preserved. Two patients with benign teratoma had a recurrence due to incomplete primary resection. In one patient who underwent orchiectomy for benign teratoma, two metachronous teratomas were detected in the contralateral testis 6 years after primary surgery.ConclusionsIn children, most testicular tumors are benign, especially before puberty. If testis-preserving surgery is contemplated, complete excision of the tumor should be ascertained. The possibility of metachronous bilateral tumors should be considered in the follow up of testicular teratomas.
