[Idiopathic granulomatous orchitis]

Idiopathic granulomatous orchitis is a rare testicle lesion of unknown etiology. This paper illustrates 10 cases studying their presentation, location, ultrasound and histological diagnosis and therapy. A testicular injury background and self-immune reaction appear as likely causes of this entity. Differential diagnosis with testes malignant tumours can only be reached after orchiectomy and a subsequent histological examination.
