Congenital granular cell tumor (CGCT) in newborns is a rare tumor occurring in the oral cavity, leading to difficulty in breast-feeding, mouth closure, and even respiration. This is rarely diagnosed perinatally and may be confused with a wide range of congenital, benign, or malignant growths during the clinical examination. The CGCT may be studied by ultrasonography to get a positive affirmation on the clinical diagnosis and, for basic pre-surgical guidance before excision. A histological study is needed to provide a final diagnosis and rule out any possible aggressive tumors. The report highlights the role of dental surgeons and clinical pathologists in providing prompt primary care for an unusual pediatric swelling under rural Indian settings.
