增生性肌炎误诊软组织恶性肿瘤经验总结

Summary on experience of misdiagnosis of soft tissue malignant tumor in proliferative myositis

增生性肌炎是一种发生在肌肉组织的炎症性疾病,临床罕见,以局部软组织包块迅速增大为主要症状,病情变化快,容易误诊为软组织恶性肿瘤,实质上是肌纤维周围的纤维结缔组织增生性炎症,属增生性良性病变,发病机制不明确,影像检查有典型性表现,组织病理学是诊断金标准,细胞学是重要诊断依据,其具自限性,预后良好。我科2019年6月收治1例增生性肌炎,分析诊治经过及误诊原因,复习相关文献并总结。

Proliferative myositis is an inflammatory disease occurring in muscle tissue,which is rare in clinic.The main symptom is the rapid increase of topical soft tissue mass.The disease changes rapidly and is easily misdiagnosed as soft tissue malignant tumor.It is essentially proliferative inflammation of fibrous connective tissue around muscle fibers,which is a proliferative benign lesion with unclear pathogenesis and typical imaging findings.Histopathology is the gold standard for diagnosis,and cytology is an important diagnostic basis.It is self-limiting and has a good prognosis.A case of proliferative myositis was treated and admitted to our department in June 2019.The diagnosis and treatment process and misdiagnosis reasons were analyzed,and related literatures were reviewed and summarized.
