    Bone Tumour Reference Centre at the Institute of Pathology, University Hospital Basel, University of Basel, Schoenbeinstrasse 40, Basel 4031, Switzerland. Electronic address:
    The jaws combine several unique properties that mainly result from their distinct embryonic development and their role in providing anchorage for the teeth and their supporting structures. As a consequence, several bone-related lesions almost exclusively develop in the jaws (eg, osseous dysplasias, ossifying fibromas), have distinct clinical features (eg, osteosarcoma), or hardly ever occur at this location (eg, osteochondroma, enchondroma). The specific characteristics of these tumors and tumorlike lesions are outlined in this article. Read More

    Benign Bone Conditions That May Be FDG-avid and Mimic Malignancy.
    Semin Nucl Med 2017 Jul 12;47(4):322-351. Epub 2017 Apr 12.
    Department of Radiology and Nuclear Medicine, Deventer Ziekenhuis, Deventer, The Netherlands.
    Positron emission tomography with the radiotracerF-fluoro-2-deoxy-d-glucose (FDG) plays an important role in the evaluation of bone pathology. However, FDG is not a cancer-specific agent, and knowledge of the differential diagnosis of benign FDG-avid bone alterations that may resemble malignancy is important for correct patient management, including the avoidance of unnecessary additional invasive tests such as bone biopsy. This review summarizes and illustrates the spectrum of benign bone conditions that may be FDG-avid and mimic malignancy, including osteomyelitis, bone lesions due to benign systemic diseases (Brown tumor, Erdheim-Chester disease, Gaucher disease, gout and other types of arthritis, Langerhans cell histiocytosis, and sarcoidosis), benign primary bone lesions (bone cysts, chondroblastoma, chondromyxoid fibroma, desmoplastic fibroma, enchondroma, giant cell tumor and granuloma, hemangioma, nonossifying fibroma, and osteoid osteoma and osteoblastoma), and a group of miscellaneous benign bone conditions (post bone marrow biopsy or harvest status, bone marrow hyperplasia, fibrous dysplasia, fractures, osteonecrosis, Paget disease of bone, particle disease, and Schmorl nodes).

We report a rare case of concomitant CGCG and aneurysmal bone cyst in a two-year-old male child, involving the coronoid and condylar process. Young age, large tumor, its aggressive nature, and future growth of orofacial region pose a significant challenge in the management of such conditions. Read More
