A case of pachydermoperiostosis treated by oral administration of a bisphosphonate and arthroscopic synovectomy

Abstract

Pachydermoperiostosis (PDP) is a rare hereditary disorder characterized by pachydermia, digital clubbing, and periosteal hypertrophy. Here, we report a case of PDP showing symptoms consistent with arthritis, which was treated by oral administration of risedronate sodium and arthroscopic synovectomy.
