Objectives:
We report a review of all patients with testicular tumors undergoing surgery in our Hospital over a 13 year period. There were 151 cases, 50 of them were reported as non germ cell tumors (33%).
Methods/Results:
42% of them were haematopoietic tumors, lymphomas and leukemias. 30% of them were non neoplastic tumors, including vascular tumors and granulomatous orchitis. 12% were identified as Leydig or Sertoli cell tumors. 10% were metastases.
Conclusions:
Non germ cell tumors were more frequent in adults (78%) than in children (22%). Among children, 82% of the neoplasias were leukemic infiltration of the testicle.

Cancer-Critical Genes II: Tumor Suppressor Genes
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
