title: [Testicular teratoma in infancy].
abstract: The authors describe a case of testicle-based teratoma, in a 20-month old boy. Due to the characteristics of the palpation and its eventual transillumination, it may be confused with a hydrocele. They stress its rarity and on the basis of a review of the literature, they explain its histological peculiarities and refer to its prognosis, usually benign, when it is diagnosed at about 2 years of age, providing that a very careful examination of the histological sections rules out the presence of anaplastic cells. Finally there is a short discussion on the possibilities of complementary therapy when there are metastases.
