Pachydermoperiostosis: dermatological, neurological and radiological observations.

A case of pachydermoperiostosis is described. Interesting features were the presence of carpal and tarsal tunnel syndromes, chronic leg ulcerations and large calcification of the Achilles tendon. Neurological alterations were explained by the stenosis of the tunnels secondary to the periosteal apposition. Chronic leg ulcerations were probably due to neurological and circulatory alterations.
