Proliferative myositis of the buccinator muscle: a case with immunohistochemical and electron microscopic analysis

A case of proliferative myositis of the buccinator muscle is reported. To our knowledge, the present case is the second reported in the oromaxillary region. From immunohistochemical and electron microscopic studies, it seems likely that the ganglion-like cells are derived from myofibroblasts or macrophages rather than from striated muscle cells.
