A case of granulomatous orchitis in a hemodialysis patient

A case of granulomatous orchitis in a 47-year-old patient is described. He had a history of recurrent pyelonephritis and subsequent chronic renal failure, and was under treatment with hemodialysis therapy. He presented with painful swelling of the right scrotal contents accompanied by fever. After the unsuccessful treatment with antibiotics, an exploration of the right scrotal contents revealed the testis replaced by a hard yellow mass. An orchiectomy was performed and granulomatous orchitis was diagnosed pathologically. The clinical and etiological aspects of this rare inflammatory disease of the testis are reviewed. It is important to recognize this disease, because this is often initially thought to be neoplastic. Although the cause of this disease is still controversial, it is supposed to be associated with sperm extravasation caused by urinary tract infection or trauma.
