摘　　要：对增生性肌炎的组织学、组织化学和免疫组织化学进行观察。免疫组织化学染色结果显示：Ｖｉｍｅｎｔｉｎ、Ａｃｔｉｎ标记细胞呈阳性反应。Ｄｅｓｍｉｎ、ＡＡＣＴ、ＥＭＡ、Ｃｙｔｏｋｅｒａｔｉｎ和Ｓ－１００标记为阴性。组织化学染色结果显示：Ｍａｓｓｏｎ染色细胞胞浆呈红色。研究结果提示：增生性肌炎属于炎性肌纤维母细胞瘤样增生性病变。cases with proliferative myositis were studied by immunohistochemical method. The results revealed that the cells were positive for vimentin, actin and negative for desmin, AACT, EMA, cytokeratin and S-100protein. The cytoplasm was stained red in Masson's stain. These findings suggest that proliferative myositis be derived from myofibroblasts.
