Synovial chondromatosis is a well-known, well-described clinical and histopathologic entity. Occasionally, loose bodies in the knee joint can continue to grow and become large enough to impinge on joint motion. Extremely large synovial chondromata are relatively rare in the knee joint and have only been described in singular case reports in the orthopaedic literature. We describe two cases representing the spectrum of this disease process occurring in the popliteal fossa, simulating bony and/or soft tissue neoplasm. Case 1 demonstrates a large ossified chondroma, while Case 2 demonstrates a large chondroma without much calcification and with no ossification present. Because of the rarity of these lesions, preoperative staging studies, including CT scan, bone scan, and angiography, are usually warranted to help in the preoperative planning. Open biopsy with adequate tissue sampling is necessary to make an accurate histopathologic diagnosis. Once diagnosis is made, local excision for removal of the mechanical block to motion results in "cure"; local recurrence has not been noted.
滑膜软骨瘤病是一种广为人知且有详细描述的临床和组织病理学实体。偶尔，膝关节内的游离体可继续生长并变得足够大，从而影响关节活动。极其巨大的滑膜软骨瘤在膝关节中相对罕见，仅在骨科文献的个别病例报告中有描述。我们描述了两例发生在腘窝的这种疾病过程的病例，它们模拟了骨和/或软组织肿瘤。病例1显示一个大的骨化软骨瘤，而病例2显示一个大的软骨瘤，钙化不多且无骨化。由于这些病变罕见，术前分期检查，包括CT扫描、骨扫描和血管造影，通常是必要的，以帮助进行术前规划。进行充分组织采样的开放活检对于做出准确的组织病理学诊断是必要的。一旦确诊，通过局部切除去除运动的机械性阻碍可实现“治愈”；尚未发现局部复发情况。
