title: [Leydig cell tumor: our experience. Bibliographic review].
abstract: OBJECTIVE
  To report the case-series of Leydig cell tumors diagnosed at our center, and to perform a bibliographic review on the topic.
  
  
  METHODS
  Retrospective review of the clinical records of all patients with the diagnosis of Leydig cell tumor in our center over the last 12 years. We evaluated the clinical, diagnostic and therapeutic features, as well as outcomes.
  
  
  RESULTS
  Four patients were diagnosed and treated in our department over this period. Mean patient age of the time of diagnosis was 51 years. Each of our cases have a different presentation. The two patients who underwent sperm analysis had azoospermia. None of the cases showed anomalous hormonal studies. Seventy-five percent of the cases showed ultrasound signs compatible with testicular neoplasia. In all of them surgical treatment was undertaken (inguinal orchyectomy); one of the patients underwent chemotherapy due to metastasis, having a good response. Mean follow-up is 76 months.
  
  
  CONCLUSIONS
  It is a rare testicular tumor. Inguinal orchyectomy is the treatment of choice. Its good outcome is remarkable.
