Osteochondroma (OC) is one of the most common benign condylar tumours having both chondroma and osteoma. However, this tumour is most frequently found on the metaphyses of long bones and is unusual on the skull. When it affects the mandibular condyle, the cause could be due to trauma to the tempero mandibular joint (TMJ). Here, in this report we present a rare case of osteochondroma of left condyle region in a 36-year-old man. The patient had noticed pain in the left TMJ for six months. The lesion is surgically removed and histologically evaluated which composed of chondrocytes dispersed in hyaline matrix along with a rim of calcified bone at one end.
骨软骨瘤（OC）是最常见的同时具有软骨瘤和骨瘤成分的良性髁突肿瘤之一。然而，这种肿瘤最常发生于长骨的干骺端，在颅骨上较为少见。当它累及下颌骨髁突时，病因可能是颞下颌关节（TMJ）受到创伤。在此，我们报告一例36岁男性左侧髁突区骨软骨瘤的罕见病例。患者左侧颞下颌关节疼痛已持续6个月。该病变经手术切除并进行组织学评估，其由分散在透明基质中的软骨细胞组成，一端还有一圈钙化骨。
