INTRODUCTION
Synovial chondromatosis (SC) commonly involves large joints such as the knee and hip with smaller joints being less frequently involved. Extra-articular involvement is very rare, and here, we are presenting the first case of giant extra-articular SC originating from the ankle joint.
CASE REPORT
A 42-year-old male presented to the outpatient department with painless swelling over the lateral malleolus for 2 years. Diagnostic imaging suggested the involvement of the synovial lining with the swelling. The mass was excised and histopathology proved the diagnosis of SC.
CONCLUSION
Extra-articular involvement in SC has been mainly reported in the synovial sheath or bursae of the hand and foot, but they can involve ankle joint also. In recent times, there have been concerns about potential malignant transformation of these lesion to chondrosarcoma, diagnosing these lesions have become important.
引言
滑膜软骨瘤病（SC）通常累及膝关节和髋关节等大关节，较少累及小关节。关节外受累非常罕见，在此，我们报告首例起源于踝关节的巨大关节外滑膜软骨瘤病。
病例报告
一名42岁男性因外踝无痛性肿胀2年就诊于门诊。诊断性影像学检查提示滑膜层受累伴肿胀。肿物被切除，组织病理学证实为滑膜软骨瘤病。
结论
滑膜软骨瘤病的关节外受累主要报道于手足的滑膜鞘或滑囊，但也可累及踝关节。近年来，人们担心这些病变可能恶变为软骨肉瘤，因此对这些病变进行诊断变得很重要。
