Gonococcal arthritis case report.

In the case reported, the diagnosis of gonococcal arthritis unfolded over the course of 1 week and was not fully conclusive until presumptive therapy was initiated. Although the clinical, microbiologic, and immunologic characteristics of gonococcal arthritis can be differentiated from other types of bacterial arthritides, not all textbook symptoms are present at one time in one particular case. There also are subtle signs that are involved. In this case study, there was little definitive evidence that stood out to confirm the diagnosis. It was the interdependence of a complete history, serologic and radiographic studies, clinical presentation, and demographic considerations that led to an accurate diagnosis and timely treatment of gonococcal arthritis.
