Congenital Epulis of the Newborn



Congenital Epulis of the Newborn


Susan Müller, DMD, MS










High-power photomicrograph of a congenital epulis shows a uniform epithelium with atrophy of the rete ridges. Cells with abundant granular cytoplasm and a basophilic nuclei are seen in the lamina propria.






Unlike the granular cell tumor, the granular cells in congenital epulis are not immunoreactive for S100 protein. The overlying epithelium shows isolated melanocytes image positive with S100 protein.
