RESUMO
INTRODUCTION: Congenital epulis, also known as Neumann's tumor, is an uncommon benign tumor of the oral mucosa that occurs in newborns. It is a rare condition, with fewer than 250 reported cases worldwide. The exact cause or underlying mechanism of this tumor is still not well understood. CASE PRESENTATION: We present a three-day-old male neonate who presented with a swelling on the gingiva that had been present since birth. The infant did not encounter any difficulties with feeding or breathing. The patient had a single, round, pink swelling measuring 2 × 2 × 1 cm on the right maxillary alveolar ridge. The swelling was surgically removed under general anesthesia. Microscopic examination revealed large polygonal cells with abundant granular cytoplasm, centrally located nuclei indicating a diagnosis of congenital epulis. CLINICAL DISCUSSION: Clinical manifestation could vary from no symptoms to feeding difficulty and rarely airway obstruction. It usually tends to grow on anterior alveolar ridge of the newborns, more on the maxilla than on the mandible. Confirmation of the diagnosis is by histopathology, which commonly shows proliferation of polygonal round cells with eosinophilic granular cytoplasm and round central nucleus. Congenital epulis can be approached using different management techniques depending on the size, site of the tumor, and presenting symptoms of the newborns. CONCLUSION: Congenital epulis is rare, but it has to be considered as a differential diagnosis for gingival swelling among neonates.
