Incidence of arthro-osteitis in patients with pustulosis palmaris et plantaris

Arthro-osteitis at the anterior chest wall was found in 12 (9·4%) out of 128 consecutive patients with pustulosis palmaris et plantaris. This finding indicates that the concomitance of arthro-osteitis with PPP is not incidental but is based on some common aetiological factor. We propose a term `pustulotic arthro-osteitis' for this condition.
