Ectopic salivary gland cyst in the neck: Association with congenital plunging ranula

Congenital ranula is rare. We report a large, symptomatic, congenital plunging ranula associated with a salivary gland cyst in the neck. To the best of our knowledge, this is the first such reported case. Even though both the cysts had their origin from the sublingual gland, only the cervical cyst had a capsular covering. Herniation of a part of the immature sublingual gland anlage through a congenital mylohyoid defect, its separation, and subsequent maturation could explain this occurrence.
