Abstract

Osteochondroma with secondary synovial chondromatosis is rare in the temporomandibular joint (TMJ), so we retrospectively reviewed 210 such patients who presented to our hospital from 2001-2013. The final sample included 3 patients with secondary synovial chondromatosis (mean (SD) age 40 (??) years), all of whom had symptoms of disorders of the TMJ. Condylar neoplasms and loose bodies were found during operation. Histopathological examination showed a bony growth capped with hyaline cartilage and clustering chondrocytes, with partial calcification and ossification of the loose bodies, and primary osteochondroma with secondary synovial chondromatosis was diagnosed. There were no recurrences during a follow-up that ranged from 3 months to 5 years. The presence of loose calcified bodies in osteochondroma is a possible sign of secondary synovial chondromatosis.

摘要

伴有继发性滑膜软骨瘤病的骨软骨瘤在颞下颌关节（TMJ）中较为罕见，因此我们回顾性分析了2001年至2013年期间在我院就诊的210例此类患者。最终样本包括3例继发性滑膜软骨瘤病患者（平均（标准差）年龄40（？？）岁），所有患者均有颞下颌关节紊乱症状。手术中发现髁突肿物和游离体。组织病理学检查显示骨生长表面覆盖透明软骨且有聚集的软骨细胞，游离体有部分钙化和骨化，诊断为原发性骨软骨瘤伴继发性滑膜软骨瘤病。在3个月至5年的随访期间无复发。骨软骨瘤中存在钙化游离体可能是继发性滑膜软骨瘤病的一个征象。
