Multicenter retrospective study on benign testicular tumors in children: save as much as you can……please.

BACKGROUND

Testicular tumors (TT) are infrequent in pediatric patients, representing 1% of pediatric solid tumors; benign testicular tumors (BTT) are the most common. We present a multicenter study aiming to describe the incidence, histology and surgical technique of BTT, with special emphasis on which approach could present better outcomes.

METHODS

The records of pediatric patients diagnosed with BTT between 2005 and 2020 from 8 centers in 5 different countries in Latin-America, were reviewed.

RESULTS

Sixty two BTTs were identified. 73% tumors presented as a testicular mass, and 97% underwent testicular ultrasound as the initial imaging study, all of them had findings suggestive of a benign tumor. 87% had preoperative tumor markers (AFP and BHCG). In 66%, an intraoperative biopsy was done and 98% of the intraoperative biopsies were concordant with the final pathology report. Tumorectomy was performed in 81% of patients and total orchiectomy in the remaining 19%. Six percentage of patients underwent a subsequent orchiectomy. Mean follow-up was 39 months (1-278 months) where no cases of atrophy were observed clinically or on ultrasound. Fertility was not evaluated in this series.

CONCLUSIONS

Proper management of BTTs is essential to avoid unnecessary orchiectomies. Preoperative ultrasound associated with intraoperative biopsy seems accurate in identifying benign pathology, thus enabling conservative testicular surgery with safety margins. Based on this multicenter series, we suggest performing an intraoperative biopsy with subsequent tumorectomy preserving healthy testicular tissue in BTT.
