Total osteolysis of the mandibular condyle in progressive systemic sclerosis

This report calls attention to the complete resorption of the mandibular condyle in progressive systemic sclerosis (scleroderma), a previously unreported finding. This was associated with osteolysis of the ipsilateral coronoid process, both mandibular angles, and autoamputation of the fingertips. The Panorex provides a simple, effective method for studying the mandible in systemic sclerosis. Similar mandibular osteolysis with vinyl chloride exposure is noted.
