Palmar erythema in rheumatoid arthritis.

Palmar erythema ("liver palms") was seen in 32/100 consecutive patients with classical rheumatoid arthritis and in 10/100 patients with various other internal diseases (p less than 0.001). Age of the patients, sex, duration of disease, titer of rheumatoid factor, stage of disease, erythrocyte sedimentation rate and frequency of volar tenosynovitis of the hands did not differ between patients with and those without palmar erythema. Ulnar deviation of the fingers was less common and the hemoglobin content of the blood was higher in patients with palmar erythema.
