Insights
Testicular-sparing surgery (TSS) is often used for benign testicular masses in children. This study reviewed outcomes, noting successful TSS in seven of eleven pre-pubertal males, with unique findings including Leydig cell hyperplasia and testicular regrowth after cyst removal.
Area of Science:
- Pediatric Urology
- Surgical Oncology
- Endocrinology
Background:
- Benign intratesticular masses are common in pre-pubertal males, often favoring testicular-sparing surgery (TSS).
- Understanding outcomes of these procedures is crucial for pediatric surgical management.
Purpose of the Study:
- To review the outcomes of benign testicular lumps in children treated at a tertiary pediatric center over 7.5 years.
- To evaluate the efficacy and complications of testicular-sparing surgery (TSS) in pediatric patients.
Main Methods:
- A retrospective review of pediatric benign testicular lesions was conducted from January 2008 to June 2015.
- Data analysis focused on patient demographics, lesion types, surgical interventions, and outcomes.
Main Results:
- Twelve benign intratesticular tumors were identified, primarily in pre-pubertal males (11 cases).
- Common diagnoses included teratomas, epidermoid cysts, and Leydig cell hyperplasia.
- Testicular-sparing surgery (TSS) was attempted in 11 pre-pubertal cases, with successful outcomes in seven; notable findings included testicular reconstitution after large cyst removal and one case of epidermoid cyst recurrence.
Conclusions:
- This series highlights Leydig cell hyperplasia presenting with unilateral precocious puberty, a novel finding.
- Evidence suggests testicular regeneration is possible after TSS for large intrasesticular cysts.
- Recurrence of epidermoid cysts following TSS was observed, indicating the need for vigilant follow-up.
Introduction:
A preponderance of benign intratesticular masses in pre-pubertal males encourages testicular-sparing surgery (TSS).
Objective:
To review outcome of benign testicular lumps in children managed at a tertiary pediatric center more than 7.5years.
Methods:
A retrospective review of pediatric benign testicular lesions from January 2008 to June 2015 was performed.
Results:
There were twelve benign intratesticular tumors. Of these, 11 were in pre-pubertal males; comprising four teratomas, two epidermoid cysts, one dermoid cyst, two cases of Leydig cell hyperplasia, one cystic dysplasia of the rete testis and one large simple intratesticular cyst. We illustrate a case of Leydig cell hyperplasia presenting with precocious puberty limited to the ipsilateral hemi-scrotum. TSS was attempted in all 11 pre-pubertal cases, but successfully performed in seven. TSS was possible for a large testicular cyst seemingly replacing the entire testis, with evidence that the testis reconstituted itself after surgery. Recurrence of an epidermoid cysts reported.
Conclusion:
For the first time in the literature, this series reports Leydig cell hyperplasia presenting with ipsilateral hemi-scrotal changes of precocious puberty; shows evidence that the testis reconstitutes itself after TSS for a large cyst; and reports recurrence of an epidermoid cyst after TSS.
