Oral Congenital Cystic Choristomas: A Case Report

Abstract

Solitary choristomas containing gastrointestinal mucosa occur rarely in the tongue and the oral mucosa and usually present as an asymptomatic mass. This report documents the occurrence of two congenital intraoral cystic choristomas in a 5-month-old male infant. The cysts were located on the dorsum of the base of the tongue and left floor of mouth anterior to the lingual cyst. Both cysts were lined by nonkeratinizing squamous epithelium and gastric, intestinal, and respiratory epithelium. The cysts were excised by an oral approach.

Lingual cyst lined by squamous epithelium

“…Surgical excision appears to be efficacious with relatively minimal morbidity as demonstrated by the above two case presentations as well as cases presented in the literature [2][3][4][5][7][8][9][11][12][13][14]. The current terminology should be refined to avoid implications of pathophysiology, but rather sufficient description to allow these lesions to be further studied.…”

Foregut duplication cyst presenting as lingual swelling: Case report and review of literature

“…[28914] These masses involve the anterior aspect of the tongue in 60% of cases. [910] Some are asymptomatic, and some cause various degrees of feeding and breathing difficulties or manifest in unexpected ways, such as recurrent bleeding[13] or a brownish discharge from a lingual sinus.…”

“…[10] Most of these cysts are solitary, but in some cases more than one cyst has been present. [1415]…”

A Mixed Heterotopic Gastrointestinal and Respiratory Cyst of the Oral Cavity with an Intraosseous Component

“…10,11 The most common location is the ventral surface of the anterior tongue, with extension to the floor of the mouth. 10,12 Other reported sites of involvement include the lips, 5 the larynx, 13 the submandibular glands, 7,14,[15][16][17][18][19][20] and the anterior neck. 21 Although the exact mechanism is unknown, there have been several proposed theories on the pathogenesis of heterotopic gastrointestinal and/or respiratory cysts of the oral cavity.…”
