ABSTRACT. We have investigated the presence of α-actin and vimentin in biological samples harvested from two patients one diagnosed with fibro-inflammatory epulis and one diagnosed peripheral giant cell granuloma. In the fibro-inflammatory epulis, labelling for vimentin was important for the connective cells in the deep chorion but positive vimentin cells were observed also near chronic inflammatory reaction. Actin immunolabelling was positive for the myofibroblasts in the deep chorion, in the smooth muscle cells in the mid-vessels walls or in the myofibroblasts near the imflammatory process.
Keywords: α-actin, vimentin, myofibroblast, imunolabelling, epulis
