Ultrastructural observations on a gingival granular cell tumor (congenital epulis)

A congenital epulis from a 1-hour-old female infant was subjected to ultramicroscopic observations. The lesion was found to be quite similar to the usual granular cell tumors as previously studied. The finding of junctional complexes between some of the granular cells suggested that these cells may be of epithelial origin. This, however, is not entirely conclusive and further avenues for future studies are suggested.
