A 35-year-old white female comes to your office with a 3-month history of the gradual onset of pain and tenderness in the wrists and hands. She also complains of 1 hour of morning stiffness. She denies rash, fever, or skin changes. On physical examination she has symmetric swelling of the proximal interphalangeal joints and metacarpophalangeal joints. Motion of these joints is painful. She has no rash or mouth ulcers. Radiographs of the hands and wrists are negative, and a chest film is unremarkable. Her CBC is normal, but the sedimentation rate is elevated at 40 mm/hr. Latex fixation for rheumatoid factor is negative, and an antinuclear antibody test is negative. <?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" />

Rheumatoid arthritis. (suggestive history*; RA factor negativity does not exclude diagnosis; radiographs maybe normal early in the disease; female gender is a risk factor). *The ARA criteria for diagnosing RA are met in this case.
