[Acute scrotal involvement as onset of a testicular Sertoli cell tumor in a two-month-old baby].

Sertoli cell tumour is an uncommon neoplasm, either in the adult and in the pediatric age groups. An intrascrotal, slowly growing, painless swelling generally represents its clinical onset. Orchiectomy definitively is successful in these patients, since Sertoli cell tumour very rarely metastatise elsewhere. The case of a two-month old baby in which an acute intrascrotal involvement (requiring immediate surgical therapy), was the atypical onset of a testicular Sertoli cell tumour, is described. The hystogenesis as well as the clinical and pathological peculiarities of this neoplasm in pediatric patients are discussed.
