Abstract

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.

Keywords: Chondroma; Extraskeletal chondroma; TMJ; Temporomandibular joint.
