Focal myositis, a benign inflammatory pseudotumor, is a relatively newly defined clinicopathologic entity which arises as a rapidly enlarging swelling within an isolated skeletal muscle. It occurs most often in the lower extremity, and we are reporting what we believe to be the first cases of perioral involvement. There is no apparent age or sex preference. Focal myositis must be differentiated from neoplasm, nodular pseudosarcomatous fascilitis, proliferative myositis, myositis ossificans, polymyositis, and, in the oral region, salivary gland lesions and hypertrophic branchial myopathy. No lesions have recurred.
局灶性肌炎是一种良性炎症性假瘤，是一种相对较新定义的临床病理实体，表现为孤立骨骼肌内迅速增大的肿块。它最常发生于下肢，我们报告了我们认为是首例累及口周的病例。发病无明显年龄或性别倾向。局灶性肌炎必须与肿瘤、结节性假肉瘤性筋膜炎、增生性肌炎、骨化性肌炎、多发性肌炎相鉴别，在口腔区域还需与涎腺病变和肥厚性鳃肌病相鉴别。目前尚无病变复发。
