Brucellosis is a zoonosis caused by gram negative coccobacilli and it is an endemic infectious disease in Turkey. Infection is usually acquired as a result of direct contact with infected animals or by consuming milk or cheese freshly made from them. There exists a wide spectrum of clinical signs and symptoms in brucellosis. Many systems including musculoskeletal, gastrointestinal, cardiovascular and genitourinary may be involved in brucellosis. The genitourinary system is affected in 2% to 20% of the cases with brucellosis. The most common forms of brucellosis are epididymo-orchitis, testicular abscess and atrophy. The serum agglutination test to detect the presence of antibodies is a reliable test in patients with urogenital symptoms. Long-term and combined antibacterial therapy have been found to be effective in brucellosis. We present two cases undergoing orchiectomy because of testicular mass before the diagnosis of brucellosis was made.
