Multiple Congenital Granular Cell Epulis Involving Different Parts of the Oral Cavity: A Case Report.

Congenital granular cell epulis (CGCE) is a rare disease, particularly when it affects multiple oral and maxillofacial regions. We present the case of a female neonate with 4 asymptomatic masses attached to the maxillary and mandibular gingiva as well as the tongue. Due to the size of the masses causing feeding and respiratory difficulties, lesion removal was performed under general anesthesia. Histopathological analysis revealed tightly arranged polygonal cells with abundant granular eosinophilic cytoplasm. Immunohistochemically, the cells were negative for Smur100 (S-100), neuron-specific enolase (NSE), cluster of differentiation (CD) 68, and Sry-related HMG box (SOX)-10, and positive for alpha-1-antitrypsin (AAT) and vimentin. The diagnosis of multiple CGCEs was established through clinical examinations, histomorphometrical, and immunohistochemical analyses. In conclusion, CGCE should be considered in the differential diagnosis of intraoral lesions in neonates.
