title: [Testicular metastasis as first clinical expression of unknown origin malignant melanoma].
abstract: OBJECTIVE
  To report a rare process and to stimulate clinicians and pathologists to have this possibility present in their diagnoses.
  
  
  METHODS
  We report the case of an adult male with pain and swelling in the left inguinal region and increased volume of the homolateral testicle.
  
  
  CONCLUSIONS
  It is appropriate to bear in mind the possibility of testicular metastasis of a primary unknown tumor in adult males since metastatic affectation can constitute the first manifestation of the disease.
