Fungal arthritis simulating juvenile rheumatoid arthritis.
Petriellidium boydii is often isolated from maduromycosis but has recently been associated with arthritis. A previously healthy 6-year-old boy developed chronic purulent arthritis of the knee after a bicycle accident. Culture of aspirate grew no pathogens and antibiotic treatment had no effect. Culture of synovial fluid grew P boydii, which responded initially to amphotericin but reappeared after six months. Subsequent treatment with miconazole was stopped after development of haematuria. The fungus was sensitive to ketoconazole, and treatment with this drug cured the infection. With the introduction of ketoconazole it is of practical importance to recognise fungal infections.
