Case in brief
A female neonate presented with four asymptomatic masses involving the maxillary and mandibular gingiva and tongue. Their size caused feeding and respiratory difficulties, prompting removal under general anesthesia. Histology showed tightly arranged polygonal cells with abundant granular eosinophilic cytoplasm. The cells were negative for S-100, NSE, CD68, and SOX10, and positive for AAT and vimentin. Clinical, histomorphometric, and immunohistochemical findings established multiple congenital granular cell epulis.
What made this case unusual
The lesions involved several distinct oral sites—the maxillary and mandibular gingiva and tongue—rather than a single location, and their size caused both feeding and respiratory difficulties.
Diagnostic / clinical pearl
In neonates with intraoral masses, include congenital granular cell epulis in the differential; histology and immunohistochemistry can support the diagnosis.
