title: [An occult Leydig-cell tumor in a cryptorchid testis].
abstract: OBJECTIVE
  A case of Leydig cell tumor in a cryptorchid testis is described.
  
  
  METHODS
  A 55-year-old man presented with no specific scrotal symptoms. A cryptorchid testis was discovered on physical examination and the patient was submitted to orchidectomy.
  
  
  RESULTS
  A solid, well-circumscribed, round nodule of 0.8 cm in diameter was found in an atrophic testis. The histological examination showed a Leydig cell tumor with crystals of Reinke and immunostaining with vimentin.
  
  
  CONCLUSIONS
  Leydig cell tumor may be related with cryptorchidism.
