Testicular sarcoidosis

Urogenital sarcoidosis is very rare. To date, only about 60 cases have been described in the literature.1 This corresponds to only 0.2% of all cases of sarcoidosis diagnosed. When the urogenital system is affected, it is usually the epididymis that is involved, followed by the testis and vas deferens.2 Sarcoidosisealso known as Boeck's sarcoid or Schaumann-Besnier diseaseeis a rare chronic disorder (prevalence of 1e40 per 100,000 inhabitants) characterised by non-necrotising, epitheloid cell granulomas occurring in different organs.3 The aetiology is still unclear, with the onset of disease typically in young adults. Familial clustering is seen in 5e19% of cases, which is why a significant genetic background is assumed.4,5 The clinical picture can take on very different forms, since basically any organ can be involved. It is often a chance finding made during other diagnostic procedures.3
