Intracapsular and paraarticular chondromas are rare benign tumors. The authors report four such lesions, three of which occurred about the knee and one at the hip. Radiographs showed calcified soft-tissue masses in the infrapatellar region of the knee in three patients. In the hip, the lesion was not visible on conventional radiographs. Three lesions originated from the joint capsule and one was extracapsular. These lesions should be differentiated from synovial chondromatosis and other calcified lesions occurring about the joints. After local excision, the tumors usually do not recur.
关节内及关节周围软骨瘤是罕见的良性肿瘤。作者报告了4例此类病变，其中3例发生在膝关节周围，1例发生在髋关节。X线片显示3例患者膝关节髌下区域有钙化的软组织肿块。在髋关节，常规X线片上看不到病变。3个病变起源于关节囊，1个位于关节囊外。这些病变应与滑膜软骨瘤病及关节周围其他钙化病变相鉴别。局部切除后，肿瘤通常不会复发。
