Pseudallescheria boydii infection of a prosthetic hip joint--an uncommon infection in a rare location.

Pseudallescheria boydii infection of the hip joint was diagnosed 2.5 years after implantation of a prosthetic joint in a woman with rheumatoid arthritis. Cure was achieved with a 10-month course of voriconazole coupled with removal of the prosthesis and repeat surgical debridement. Pseudallescheria boydii is an environmental mold that can cause osteoarticular infection, most often not only after local trauma but also after local injections and surgical procedures. Hip involvement was rarely reported, and this is the first description of a prosthetic joint infection with Scedosporium sp.
