title: Xanthogranulomatous orchitis.
abstract: Xanthogranulomatous inflammation is an uncommon process that is usually associated with severe renal infection. We report a case of a 64-year-old man with xanthogranulomatous inflammation in the testis who presented with contralateral epididymoorchitis and a painless testicular mass. Only two prior cases of xanthogranulomatous orchitis have been reported. This case highlights the need for a broad differential diagnosis when approaching testicular masses, particularly in the setting of coincident infection.
