Congenital Eruption Cyst: A Case Report Listing Histopathological Features With Literature Review and Differential Diagnoses

Congenital eruption cysts manifest in neonates when the dental follicle separates from the crown of an erupting tooth coronal to the alveolar ridge. Clinical diagnosis can be challenging as it can present clinically similar to congenital epulis and other benign newborn pathologies. They can occasionally cause difficulty with feeding and latching, which can inhibit the newborn’s early development. Here we present a 26-hour-old twin male infant who was evaluated for a dome-shaped nodule on the mandibular alveolar ridge. Surgical excision was performed due to difficulty in latching and feeding, and histopathological analysis revealed a congenital eruption cyst. To our knowledge, this is the first case report of a congenital eruption cyst, listing the histopathological features. A thorough literature review and a list of differential diagnoses are also discussed.
