Misdiagnoses: a timely reminder

This case report of an occult infection masquerading as palindromic arthritis was misdiagnosed for almost 2 years. The episodic bouts of erysipelas were not obvious, and it was even suggested that the silicone implanted 7 years previously could possibly be inciting an autoimmune disease. Approximately 2 years after the onset of the recurrent episodes of fever, myalgias, and arthralgias, coagulase-negative staphylococci were found residing in the valve stems of bilumen breast implants, which were removed. The symptom complex disappeared and has not recurred.
