Congenital heterotopic gastrointestinal cyst of the oral cavity: report of rare case

Shira's Technique, an Alternative for the Enucleation of Cervicofacial Cysts

“…In the present study, the technique described by Shira was used, in two cases midline lesions of congenital origin and one in the submandibular region of traumatic origin; coinciding with that reported in the literature with the phenomena of mucosal extravasation in the sublingual region. However, only two cases of a cystic lesion of congenital origin have been reported [7,9], recommending complete surgical excision using the aforementioned technique, allowing easier recognition of the cystic capsule from the surrounding tissues. All these diagnoses were confirmed through histopathological study.…”

“…Currently, different techniques for enucleation have been described for head and neck cysts, such as hydro-dissection, sclerotherapy and alginate instillation described by Shira (1962), using it as a filling material inside the cystic cavity, delimiting the margins and maintaining the integrity of the lesion [5][6][7][8]. Considering the biomechanical properties of this material to improve visual access to the cyst, its properties such as malleability, setting time, low immunogenicity, biocompatibility, elasticity and its antimicrobial action improve the safety of this technique [9,10].…”

Ultrasonic Features of Uncommon Congenital Heterotopic Colon and Pancreas in the Neck: An Extremely Rare Case Report

“…Ectopic gastrointestinal cysts are rare lesions that mainly occur in the digestive tract, including the esophagus, small intestine, pancreas, gallbladder and Meckel's diverticulum (1,2). The lesions that occur in locations outside the digestive tract, such as the lips, larynx, submandibular gland, epiglottis and anterior neck, are even rarer (3,4). To date, the exact etiology of ectopic gastrointestinal cysts remains unknown.…”
