[Bilateral testicular tumors]

Five patients with bilateral testicular tumours were treated in the ten year period 1966 to 1975. In two patients the tumour appeared on both sides at the same time, while in three cases it developed 3/4, 6 and 7 years apart, respectively. The tumour was detected in one case in a retained testicle; in 4 cases the testicles were in the scrotum. Factors promoting development of the tumour and the diagnostic possibilities are discussed. It is recommended to remove the testicle by high division of the funiculus and to apply postoperative radiotherapy. In the presence of metastases administration of cytostatics is necessary. The possibilities of hormone substitution are discussed.
