      Abstract

      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 fasciitis, proliferative myositis, myositis ossificans, polymyositis, and, in the oral region, salivary gland lesions and hypertrophic branchial myopathy. No lesions have recurred.
