  • Title: Peripheral giant cell granuloma of the mandibular condyle presenting as a preauricular mass.
    Author: Ozcan C, Apaydin FD, Görür K, Apa DD.
    Journal: Eur Arch Otorhinolaryngol; 2005 Mar; 262(3):178-81. PubMed ID: 15133683.
    Abstract:
    Preauricular mass is a common symptom for patients presenting to the otorhinolaryngologist with parotid disease. Some rare extraparotid lesions, originating from the temporomandibular joint and the mandible itself, also share the same localization and therefore are to be taken into consideration for the differential diagnosis with parotid lesions. Giant cell granuloma (GCG) was first described by Jaffe in 1953. Peripheral GCG (PGCG) is an exophytic soft tissue lesion originating from the periodontal ligament and periosteum. It is located only within the oral cavity. Central GCG (CGCG) is an uncommon benign fibro-osseous lesion generally presenting as an expansible mass with cortical bone defect. It is generally located in the mandible. The brown tumor of hyperparathyroidism and giant cell tumor must be ruled out because of the microscopic similarities of these lesions. The first case of PGCG of the mandible condyle is presented, and attention is drawn to mandibular diseases for the differential diagnosis of the preauricular mass.
