Riziformbody是由纤维蛋白和细胞形成的结构,可以在滑液中发现或附着在滑膜上,并且由于其米粒状外观而具有这种面额。它们已经被描述在几种疾病中,如结核性关节炎,类风湿性关节炎,在幼年特发性关节炎(JIA)中很少见。这是一个患有4个月的左膝慢性单关节炎的男孩的情况,具有结节病家族史,其中诊断研究显示滑膜活检中存在这些网状体。诊断性调查排除了结节病,结核病和恶性肿瘤,建立JIA的诊断。我们的目的是描述我们认为是JIA中报告的第9例存在riziform尸体的病例,可能是诊断不足的,并应主要考虑在严重关节炎的情况下难以治疗。
Riziform bodies are structures formed by fibrin and cells that can be found in the synovial fluid or attached to the synovium, and have this denomination due to its rice grain-like appearance. They have already been described in several diseases such as tuberculous arthritis, rheumatoid arthritis, and rarely in juvenile idiopathic arthritis (JIA). This is the
case of a boy with a 4-month course of chronic monoarthritis of the left knee, with family history of sarcoidosis in which diagnostic investigation showed the presence of these riziform bodies in the synovial biopsy. Diagnostic investigation ruled out sarcoidosis, tuberculosis and malignancies, establishing the diagnosis of JIA. Our objective was to describe what we believe is the 9th
case reported on the presence of riziform bodies in JIA, which are probably underdiagnosed, and should be considered mainly in cases of severe arthritis of difficult medical treatment.
