Tumores testiculares en la infancia

introduction: prepubertal testicular tumours are different from those that appear during adulthood. traditionally, they were considered to be malignant, however benign testicular tumours are actually more frequent at this age. materials and methods: we analysed our experience in the treatment of testicular tumours in children < 13, with the intention of evaluating the use of partial orchiectomy. from 1984 to 2008, we diagnosed and treated 15 testicular tumours in children at our centre. we examined the therapeutic approach employed, underlining the possibility of testicular conservation in selected patients and we have analysed the results. results: the clinical presentation in 80% of the cases was an increase in testicle size with palpable mass. we performed 4 radical orchiectomies (27%) and 11 tumourectomies (73%). all the benign lesions in the final pathological anatomy were treated with tumourectomy: four epidermoid cysts, one hemangioma, one lipoma, one fibrous hamartoma, one juvenile granulosa tumour and one splenogonadal fusion. we also successfully and conservatively treated two cases of teratoma. the cases that received radical treatment were a yolk sac tumour (stage i), two mixed germ cell tumours and one gonadoblastoma. conclusions: there are more cases of benign testicular tumours than malignant tumours during puberty. in the event of a palpable testicular mass with negative tumour markers, conservative treatment by means of a tumourectomy may be considered. however, the lesion must be removed completely to prevent recurrence.
