Hajdu–Cheney syndrome: A rare acro-osteolytic disorder

Abstract

We report a case of a 35-year-old woman with Hajdu–Cheney syndrome, a very rare connective tissue disorder with about 70 cases reported worldwide since 1948. No similar disease occurred in her family. She presented with clinical features of the syndrome and left seventh cranial nerve palsy after several dental procedures. The radiographs of the skull and the hands demonstrate the abnormalities clearly.
