Para-articular osteochondroma, a benign osteoarticular tumor which develops near joints, is, unlike classical osteochondroma, extremely rare. We present the case of a 59-year-old woman who developed a calcified mass in the infrapatellar region. The differential diagnosis between chondrosarcoma, synovial chondromatosis, and para-aticular osteochondroma was only possible after resection and pathology examination of the surgical specimen.
关节旁骨软骨瘤是一种在关节附近发生的良性骨关节肿瘤，与经典骨软骨瘤不同，极为罕见。我们报告一例59岁女性，其髌下区域出现了一个钙化肿块。仅在手术标本切除及病理检查后，才得以对软骨肉瘤、滑膜软骨瘤病和关节旁骨软骨瘤进行鉴别诊断。
