Congenital gingival granular cell tumor is a rare benign lesion of uncertain origin, which has been found only in newborn infants. This article describes one such case. Our immunohistochemical study employing antibodies against S-100 protein, epithelial membrane antigen, carcinoembryonic antigen, wide-spectrum keratin, desmin and vimentin yielded data supporting the theory of a mesenchymal cell origin for this lesion.
