[Isolated testicular tuberculosis: report of a case]

In this study, a case has been reported involving a 66-year old male who was admitted for scrotal pain on the right side with possible testicular involvement, but with no associated urinary disorder. At physical examination, the right testicle was found to have increased in volume: this was further confirmed by ultrasonography, but the findings were insufficient to exclude the hypothesis of testicular cancer. An exploratory orchidectomy by upper inguinal route was therefore carried out, and histopathological examination showed the destruction of testicular tissue by several granulomas, and caseous necrosis with giant cells. Antibacterial chemotherapy was administered after an i.v. urography found no evidence of abnormality or urinary disorder, thereby eliminating an active site of genitourinary tuberculosis. This case shows the importance of considering testicular tuberculosis in the differential diagnosis of testicular enlargement in a region where this disease is endemic, despite the absence of systemic pulmonary and urinary signs of tuberculosis.
