Extraskeletal chondroma walling the temporomandibular joint: Report of a rare case and review of the literature

INTRODUCTION: Extraskeletal or soft-tissue chondroma is a rare benign cartilaginous neoplasm which usually affects hands and feet. Scientific literature only reports one previous case of this pathology in the preauricular region. PRESENTATION OF THE CASE: This report describes a rare case of extraskeletal chondroma surrounding the temporomandibular joint of a 55-year-old female patient. DISCUSSION AND CONCLUSION: Diagnosis of extraskeletal chondroma is challenging since tissue swelling, diagnostic imaging and even histopathological features may be misleading for other joint or gland pathologies.
