Septic arthritis in a previously healthy man with pan-negative infectious and rheumatologic work-up.

is the causative organism in 0.6%-1.2% of septic arthritis cases in North America and Europe, and classically presents as migratory polyarthralgias and tenosynovitis, with later development of septic oligoarthritis. In men, urine gonorrhoea nucleic amplification testing (NAAT) is the preferred diagnostic test, as its sensitivity surpasses that of joint and blood culture in disseminated infections. We present a case of a previously healthy man who presented with septic arthritis of the wrist. He denied any sexual activity in the previous year. Urine gonorrhoea NAAT and cultures were negative. However, was later identified via 16s PCR of the patient's synovial fluid, leading to a delayed diagnosis of gonococcal arthritis. In patients with septic arthritis, gonococcal infection should remain on the differential despite reported sexual history and negative urine NAAT. Clinicians should continue to follow cultures and provide antibiotic coverage until a causative organism is identified.
