title: Pediatric testicular tumors: contemporary incidence and efficacy of testicular preserving surgery.
abstract: OBJECTIVE
  Testicular tumors in the pediatric population are fundamentally distinct from their adult counterparts. We reviewed a contemporary single series from a large pediatric health science center. We also examined our experience with testis conserving surgery and then used it to develop a preoperative management algorithm.
  
  
  METHODS
  A retrospective review was performed of all testicular tumors at a single institution from 1984 to 2002. Data were compiled using the American Academy of Pediatrics testis tumor registry data collection form. We further examined partial orchiectomies for indications and outcomes with respect to cancer control and testicular viability.
  
  
  RESULTS
  A total of 51 primary testicular lesions were identified. Patient age was prenatal to 16 years with a scrotal mass the most common presentation (81%). Mature teratoma, rhabdomyosarcoma, epidermoid cyst, yolk sac and germ cell tumors accounted for 43%, 26%, 10%, 8% and 6% of cases, respectively. This distribution was markedly different from the last reported American Academy of Pediatrics data base. Organ preserving surgery was planned and achieved in 13 cases. All surgeries were successful with respect to cancer control and testicular preservation.
  
  
  CONCLUSIONS
  We believe that the higher incidence of teratoma is more representative of this population and yolk sac tumor is a minority diagnosis. The single institution review eliminates the interinstitutional referral heterogeneity that may have skewed larger data bases. Furthermore, the concept of testicular preserving surgery becomes an attractive option since we present its safety and efficacy. The management algorithm should facilitate the preoperative decision to perform less radical surgery and help preserve testicular tissue.
