[An occult Leydig-cell tumor in a cryptorchid testis].
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.
