The incidence of developing testicular cancer is % 0.2 during the entire life span.  90-95% of testiculer tumors stem from ger-minal tissue. The testicular germ cell tumors are classified as pure seminoma germ cell tumors and nonseminomatous germ cell tu-mors. The incidence rate of bilateral is 1-4%. Seminoma is the most common germ cell tumor among bilateral testicular cancer. But the most common bilateral tumor is malig-nant lymphoma. Today radical orchiectomy is considered standart therapy for testiculer tumors. We presented a case with metachro-nous testiculer tumor whose first pathologic evaluation was reported as seminoma and se-cond one was reported as nonseminomatous germ cell tumor.
