A case is reported of psoriatic arthritis (PA) with involvement of the hip joint that was treated by total hip arthroplasty.<BR>A 66-year-old female was admitted to our hospital due to left hip pain for one year. She had been suffering from psoriasis for 20 years, with polyarthralgia during last 8. On admission, her blood sedimentation rate was elevated and C-reactive protein was positive; however, the rheumatoid factor was negative. Histological examination of the synovial tissue and articular surface of the femoral head obtained at the time of surgery showed non-specific granulation and bone resorptive arthritis.<BR>Though many cases of PA have been reported, involvement of the hip joint is rare. We discuss whether this case is a rheumatoid type of PA or a coincidental association of rheumatoid arthritis and psoriasis.
