Ossifying fasciitis is a very rare disease of reactive character; however, it can mimic malignant lesions, especially osteosarcoma. We report a case of a 30-year-old woman, who experienced a rapidly growing painful lesion of the left knee joint, preceded by a trauma. The tumor was resected, and the histopathological image suggested a malignant lesion with features of an osteosarcoma. A detailed correlation with a clinicopathological and radiological analysis led to the final diagnosis of ossifying fasciitis at an extraordinary site of patellar retinaculum. Our case shows that the close similarity between ossifying fasciitis and osteosarcoma may be challenging.
骨化性筋膜炎是一种非常罕见的具有反应性特征的疾病；然而，它可能会模仿恶性病变，尤其是骨肉瘤。我们报告一例30岁女性病例，该患者在经历一次创伤后，左膝关节出现迅速生长的疼痛性病变。肿瘤被切除，组织病理学图像显示为具有骨肉瘤特征的恶性病变。通过临床病理和放射学分析的详细关联，最终诊断为髌支持带特殊部位的骨化性筋膜炎。我们的病例表明，骨化性筋膜炎与骨肉瘤之间的高度相似性可能具有挑战性。
