RARE FOREGUT CYST IN ORAL CAVITY

Abstract

Foregut cysts are rare congenital choristomas arising from abnormal development of the foregut. Choristomas may comprise several different tissue types, including salivary glands (within the jawbone or gingival tissues), cartilaginous or bony lesions (mostly on the tongue), glial tissue (most common in the nasosinusal tract), or thyroid tissue. The aim of this report is to describe the unusual case of a neonate (2 months old) with a large congenital sublingual cystic lesion preventing breastfeeding, who was initially treated as a sublingual ranula using cryosurgery without success. An incisional biopsy was performed, which diagnosed a foregut cyst. The patient was referred to the Head and Neck Surgery team for enucleation, which resolved the lesion. The patient is under follow-up with no evidence of recurrence in six months. Foregut cysts are rare congenital choristomas arising from abnormal development of the foregut.
