Abstract:
Disseminated gonococcal infection is a rare presentation of the sexually transmitted pathogen, Neisseria gonorrhoeae. Here, we report the case of a 64-year-old woman with disseminated gonococcal infection, which started with symptoms of oligoarthritis and malaise. Neisseria gonorrhoeae was identified in the carpal synovial fluid. The follow-up study revealed an absence of total hemolytic complement and complement C2 was not detected. Being relatively common, C2 deficiency has been associated with disseminated gonococcal infection in a few cases. We present a new case and discuss those previously published.
