BILATERAL SYNCHRONOUS TESTICULAR GERM-CELL CANCER

Bilateral synchronous testicular cancer is a rare occurrence usually a ssociated with similar histologic findings in each testicle. We descri be eight patients with bilateral synchronous testicular germ cell canc er, of whom four had dissimilar histologic findings. Contralateral dis ease in three patients was identified only by testicular ultrasonograp hy or intraoperative exploration of the contralateral testicle, and in two cases by palpation 6 months after identification of the primary c ancer. Treatment was determined by conventional staging and five of ei ght patients have remained free of recurrent disease.
