Bilateral synchronous testicular germ cell cancer.

摘要

Bilateral synchronous testicular cancer is a rare occurrence usually associated with similar histologic findings in each testicle. We describe eight patients with bilateral synchronous testicular germ cell cancer, of whom four had dissimilar histologic findings. Contralateral disease in three patients was identified only by testicular ultrasonography or intraoperative exploration of the contralateral testicle, and in two cases by palpation 6 months after identification of the primary cancer. Treatment was determined by conventional staging and five of eight patients have remained free of recurrent disease.
