A case of adult-type rhabdomyoma of the cheek is reported. The tumor was composed of cells presenting striated muscle differentiation, which was confirmed immunohistochemically by the positive reaction with alpha 1-sarcomeric actin demonstrating the cytoplasmic cross striations. A careful evaluation of the light microscopic features of this rare tumor, as well as the histochemical and immunohistochemical characteristics of the tumor cells would greatly help the differential diagnosis.
报告一例成人型颊部横纹肌瘤。肿瘤由呈现横纹肌分化的细胞组成，通过与α1-肌节肌动蛋白呈阳性反应的免疫组织化学证实了细胞质横纹，这显示了细胞质横纹。仔细评估这种罕见肿瘤的光镜特征以及肿瘤细胞的组织化学和免疫组织化学特征将极大地有助于鉴别诊断。
