Leydig cell tumor--comparison of results of radical and testis-sparing surgery in a single center.

Between January 1981 and December 1995, 15 patients were treated for Leydig cell tumor at our institution -- 12 by radical orchiectomy, 3 by tumor enucleation. All patients were contacted to assess the long-term outcome depending on the treatment initially chosen. Follow-up ranged from 8 to 161 months (mean 56). In no case was progressive disease documented, in 1 case local recurrence was witnessed 4 months after tumor enucleation despite negative resection margins. We conclude that a small Leydig cell tumor can safely be managed by local enucleation alone.
