Oral Foregut Cyst in a Neonate

Abstract

Oral foregut cysts are congenital choristomas that arise in the oral cavity during embryonic development from remnants of foregut-derived epithelium. This is an unusual report of a neonate with a large congenital sublingual cystic lesion, extending superficially from the left ventral tongue to the anterior floor of the mouth, impeding breast-feeding. The differential diagnosis included dermoid cyst, epidermoid cyst, mucous retention cyst, and oral lymphangioma. The treatment of choice was enucleation under general anesthesia. Histology showed a cystic lesion with a ciliated pseudostratified columnar epithelium with numerous goblet cells. Immunohistochemistry was positive for cytokeratin 7 and thyroid transcription factor 1 and negative for cytokeratin 20, resulting in a final diagnosis of an oral foregut cyst. Three weeks after surgery, the tongue had healed with good mobility, and breast-feeding could be established. No recurrence was present at 6 months of follow-up.

Congenital Huge Submandibular and Neck Teratoid Cyst in Newborn

“…This accounts for the gastric, intestinal, respiratory, and squamous epithelial lining of such cysts. 4 Because teratoid cyst is rare, diagnosis may be difficult before operation. Many other cystic diseases in the head and neck region should be excluded.…”

“…Typical clinical features of condylar OC includes facial asymmetry, temporomandibular joint dysfunctions, malocclusion (ipsilateral posterior open bite, contralateral crossbite), and even hearing loss and pain. [4][5][6][7][8] We report the diagnosis and treatment of an OC in the left condylar region, pushing the condyle seriously to the anterior direction, thus producing facial asymmetry and malocclusion.…”

“…1 Teratoid cysts exhibiting mesodermal elements are the most unusual presentation and may be lined by gastric, intestinal, respiratory, squamous, or cilitated epithelium. [1][2][3][4] Teratoid cysts containing gastrointestinal epithelium typically have been called cboristomas (tumorlike masses of normal cells with an organized architecture in an abnormal location). 5 This article describes a case of congenital huge submandibular and neck teratoid cyst in newborn.…”

Respiratory distress associated with heterotopic gastrointestinal cysts of the oral cavity: A case report

“…Although around 90 cases have been reported in the literature, it is difficult to determine the incidence of these lesions because of varied nomenclature [9]. Heterotopic gastrointestinal cysts are also referred to as choristomas, which are defined as a mass of tissue that is histologically typical of an organ in an abnormal location.…”

Oral foregut cyst in the ventral tongue: a case report

“…Foregut cysts develop from embryonic rests of foregut epithelium, and are usually observed in the abdomen and thorax 1 . Oral foregut cysts are rare but may occur on the tongue, floor of the mouth, and pharynx 2 and occasionally cause airway obstruction or feeding difficulty 3 .…”
