title: A case of congenital granular cell epulis in the maxillary anterior ridge: a study of cell proliferation using immunohistological staining.
abstract: Congenital granular cell epulis (CGCE) is a very rare benign tumor that preferentially develops in female infants. The histopathological characteristics of CGCE are very similar to a granular cell tumor, but the histological genesis is unknown. We report a case of a four-day-old female neonate who had a tumor mass in the region of the left maxillary anterior teeth. The rate of cell proliferation was determined by immunostaining with Ki-67 and PCNA, which showed labeling indexes of 16.7 and 15.1%, respectively.
