Congenital or Developmental
Inclusion Cysts
These small, white or translucent papules or cysts are present in 75% of newborns. They are usually asymptomatic and resolve spontaneously by
3 months of age.

There are 3 types of inclusion cysts:

Epstein’s Pearls: Epithelial remnants of palatal fusion located along the mid-palatal raphe of the hard palate.
Bohn’s Nodules: Heterotopic salivary gland remnants located on the buccal or lingual surface of the alveolar ridge (not the crest), or on the hard palate, away from the raphe.
Dental lamina cysts: Located on the crest of the alveolar ridge.

Congenital Epulis
Pedunculated, non-tender, spongy mass usually located on the anterior maxillary alveolar ridge. Benign in nature.
May regress spontaneously, but if it is large and interferes with feeding, may require excision. Recurrence is unlikely.
Inclusion cysts are extremely common, with Epstein's pearls being the most common variant.
Inclusion cysts usually resolve spontaneously by 3 months of age.
An Epulis is a benign, pedunculated mass.
