Congenital epulis

Congenital epulis, also known as congenital granular cell epulis or congenital gingival granular cell tumor, is a rare benign soft tissue tumor that is present at birth. It arises from the gingiva (gum tissue) of newborns, appearing as a pedunculated (stalk-like) mass protruding from the alveolar ridge of the upper or lower jaw, though the maxilla (upper jaw) is more commonly affected. The tumor predominantly affects female neonates, with a female-to-male ratio of approximately 8-10:1. The mass can vary in size from a few millimeters to several centimeters and may be single or, less commonly, multiple. The primary clinical concern with congenital epulis is its potential to interfere with feeding and breathing, particularly when the mass is large enough to obstruct the oral cavity. Despite its sometimes alarming appearance, the tumor is entirely benign and does not undergo malignant transformation. Histologically, it is composed of large cells with granular eosinophilic cytoplasm, but unlike adult granular cell tumors, congenital epulis is typically negative for S-100 protein immunostaining, suggesting a different histogenesis. The standard treatment is surgical excision, which is usually curative. The procedure is generally straightforward, especially for pedunculated lesions, and recurrence after complete removal is extremely rare. In some cases, particularly with smaller lesions, spontaneous regression has been reported, and conservative observation may be considered. No additional therapy is required following excision, and the long-term prognosis is excellent with no impact on subsequent dental development or overall health.
