Objectives: To study the incidence and characteristic of the bilateral tumours of testicle. Material and methods: It was carried out a retrospective study on a database of testiculars tumours 98 tried in our service among the years 1979 and 2004. Results: We registered 4 cases of bilateral tumours (4,1%) in the series. The interval of appearance of the second tumor oscillated between 14 months and 4 and a half years (being the medium of 47 months). In three cases the initial tumour was an embryonic Carcinoma and in one a tumour of Lydia. In two cases the second tumour was of the same type histological (embryonic Ca and tumour of Leydig), while in the other two cases of embryonic Ca, the second tumour was a seminoma and a teratocarcinoma. Regarding the histology of the first tumour, it was observed that only 3 of the 27 embryonic Ca (11%) of our series, they experienced a second neoplasia in front of 1 of the 2 tumours of Leydig (50%). Conclusions: The incidence of bilateral tumours in our series was of 4,1 %. In our series the risk of the second tumour seems to be higher in patients with Leyding tumours, therefore the lesser number of tumours do not allow us to know significantly conclusions.
