A rare case of synovial osteochondromatosis of the temporo-mandibular joint is presented. Important diagnostic information can be obtained by CT, MRI, 99m Tc bone scan and aspiration biopsy. Observation using a light microscope showed mild cellular atypia, but the hallmarks characteristic of chondrosarcoma were not found. Observation using an electron microscope showed the mature chondrocytes contained a well-developed rough endoplasmic reticulum. Histological evaluation indicated that the present case was benign synovial osteochondromatosis in an early stage.
