Pachydermoperiostosis: scintigraphic, thermographic, plethysmographic, and capillaroscopic observations.

A unique case of pachydermoperiostosis, multiple epiphyseal dysplasia, and secondary osteoarthritis is described. An additional interesting feature was the presence of acroosteolysis of the distal phalanges of fingers and toes. Scintigraphic, thermographic, plethysmographic, and capillaroscopic studies suggested increased blood flow through clubbed fingers, raising the possibility that this may play a role in the pathogenesis of pachydermoperiostosis.
