The incidence of testicular tumor is 11 times more in inguinal testes and 50 times more in intra-abdominal testes. The position of the undescended testis is related to the likelihood of carcinogenesis with the intra-abdominal location having the highest risk for malignancy. Bilateral testicular tumors are rare and 80% of bilateral tumors are metachronous. Synchronous bilateral testicular tumors are rare and bilateral synchronous testicular seminoma in a patient with bilateral cryptorchidism is very rare.
