Multiple congenital epulis of the mandibular ridge: a case report.

Congenital epulis is a very rare benign soft-tissue tumor of uncertain histogenesis, which is also known as "gingival granular cell tumor of the newborn". It occurs almost exclusively as a single tumor along the alveolar ridge of the maxilla in newborn females. Although congenital epulis is strikingly similar to the more common adult granular cell tumor histologically, in contrast to the latter congenital epulis cells are negative for S-100 protein. This case report describes a 15-day-old female infant with multiple congenital epulis of the mandibular alveolar ridge.
