A rare case of odontogenic myxofibroma , which arose from the periodontal ligament and expanded into the oral cavity resulting in an epulis‐like lesion in a 52‐yearold man, is reported including details of studies using lectin histochemistry, transmission electron microscopy (TEM), and immunohistochemistry. Most of the tumor cells, which appeared spindle‐like with abundant rough endoplasmic reticulum and some microfilaments by TEM, showed immunoreactivity for mesenchymal markers. Some tumor cells, which were polygonal and contained many microfilaments and some filament bundles, were immunoreactive for muscle markers. The present case was considered to consist of many fibroblasts and some myofibroblasts. J Periodontol 1997;68:479–484.
