Sublingual enteric duplication cyst

Heterotopic gastrointestinal cyst within the submandibular space in an adult: A case report and review of the literature

Heterotopic gastrointestinal cysts (HGIC) are rare congenital cysts that arise anywhere along the gastrointestinal tract. HGICs are infrequently reported in the oral cavity; 0.3% of HGICs are reported in the tongue and even more rarely in the submandibular space. Oral HCIGs are more common in children with only 13 reported cases in adults. In the present report, we discuss the differential diagnoses of the submandibular space lesions and describe a rare case of a very large submandibular space HGIC in an adult patient.

Intestinal duplication in the tongue: embryological and radiological point of view

Intestinal duplication in the tongue is a rare entity. Occurrence in the anterior part of the tongue is exceptional. We report an intestinal duplication in the tongue causing eating difficulties and discuss the accuracy of embryologic and histopathology knowledge as radiology. A transoral complete resection of the lesion was performed, without postoperative complications. There was no recurrence with a follow-up of 15 years.

Aspiration Avoiding Tracheostomy in Neonatal Cystic Oral Lesion

Oral cyst is uncommon in the neonatal period. Depending on the size and site of occurrence, its symptoms may vary. If not diagnosed and managed expeditiously, these oral cysts may cause significant and potentially fatal morbidity and mortality. We report a successfully managed case of oral cyst in neonate that presented with huge tongue at birth and complaints of impending airway obstruction. She was referred for tracheostomy as intubation was impossible. We attempted needle aspiration and the airway successfully relieved without the need for tracheostomy.

Oral foregut duplication cysts: A rare and fascinating congenital lesion. Case report and review of the literature

Oral foregut duplication cysts are extremely rare lesions with approximately 57 cases reported. They are congenital cysts, located in the anterior or ventral tongue, and occur predominantly in males. They are lined by one or more types of epithelia which is limited to gastric, intestinal or respiratory epithelium. The differential diagnosis includes lymphangioma, hemangioma, ranula, epidermoid cyst, teratoma and less likely a malignant process.

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

Heterotopic gastrointestinal cysts of the oral cavity are benign lesions usually discovered during infancy. Their pathogenesis is not very clear. They are rare congenital anomalies that result from remnants of foregut-derived epithelium in the head, neck, thorax or abdomen during embryonic development. The majority of these lesions occur in the anterior ventral surface of the tongue and extend to the floor of the mouth. They are confused clinically by surgeons in cases of head and neck masses in children as ranulas, dermoid and thyroglossal cysts, and lymphangioma. We report the case of a 28-day newborn with a 3.6 cm oval mass on the floor of the mouth causing difficulty eating and cyanosis during crying. Complete surgical excision was performed by an oral approach under general anesthesia. Microscopic examination revealed gastric epithelium with tall columnar mucous cells on the surface and numerous short closed crypts, resembling fundal glands and mature gastric epithelium.

•

There are less than a hundred cases reported in the medical literature.

•

It is vital for surgeons and physicians to include this pathology in their differential diagnosis.

•

Imaging studies are essential for obtaining clearer diagnostic possibilities.

•

Complete surgical resection is needed to prevent recurrence.

Enteric duplication cyst located at the posterior tongue: a rare case report and review of the literature

The lingual localization of an enteric duplication is extremely rare but may present with respiratory and feeding problems that require emergency intervention. A 7-month-old boy was brought to our clinic with feeding difficulties and tongue swelling. Physical examination showed a cystic lesion located near the left side of the tongue base that caused tongue protrusion to the contralateral side. During surgery, a 3-cm diameter opaque thick-walled cyst was found to be very closely adherent to the base of tongue, which was excised in its entirety. Following surgery, the patient fed during the early postoperative period and no complications were observed other than hypersalivation. On histological examination, a cystic lesion lined with intestinal mucosa and goblet cells was found. We present the rare case of a duplication cyst of the posterior tongue, with a literature review.

Heterotopic intestinal cyst of the submandibular gland: a case study

Heterotopic gastrointestinal cysts are rarely found in the oral cavity. Most of these cysts are lined with gastric mucosa and involve the tongue. There have been no reported heterotopic intestinal cysts of the submandibular gland that are completely lined with colonic mucosa. An 8-year-old girl presented with an enlarging swelling in the left submandibular area, and a 4-cm unilocular cyst was fully excised. The cyst was completely lined with colonic mucosa that was surrounded by smooth muscle layer, and the lining cells were positive for CDX-2, an intestinal marker, indicating a high degree of differentiation. The pathogenesis remains unclear, but it may be related to the misplacement of embryonic rests within the oral cavity during early fetal development. Although heterotopic intestinal cysts rarely occur in the submandibular gland, they should be considered in the differential diagnosis of facial swellings in the pediatric population.

Congenital oral cysts in neonates: report of two cases

Oral cysts in the neonatal period are very uncommon and may cause morbidity and mortality if not treated expeditiously. We report 2 cases of neonatal oral cysts that were managed successfully.

Lingual cyst lined by squamous epithelium

Lingual choristomas or foregut duplication cysts are infrequently reported congenital anomalies that typically present in the perinatal period, and can cause respiratory or feeding problems. These cysts are lined by epithelial cells characteristic of the upper aerodigestive tract. We describe two children who presented shortly after birth with lingual cysts lined with squamous epithelium and foci of respiratory epithelium. Unlike previously reported lingual choristomas, these cysts did not contain gastrointestinal epithelium. In both these cases, the lingual cysts were successfully excised via a transoral approach. This article will discuss the histological findings in these two cases, the differential diagnosis and attempt to classify these lesions in the context of existing terminology.

Antenatally diagnosed duplication cyst of the tongue: modern imaging modalities assist perinatal management

When a foetal abnormality is detected during routine antenatal screening, further information is required in order to plan the remainder of the pregnancy and perinatal management. If a lesion is detected in the foetal mouth or neck, there may be compromise of the foetal airway. The ex-utero intrapartum (EXIT) procedure has recently been developed to allow lifesaving foetal surgery to be performed during delivery of such cases whilst relying on placental support. Detailed antenatal assessment is essential when planning the EXIT procedure, and modern imaging modalities may be implemented. We illustrate this by reporting a rare case of enteric duplication cyst arising from the base of the tongue, which was detected on routine antenatal ultrasound scan. Subsequent imaging using foetal MRI and colour Doppler ultrasound reassured us that the foetal airway was patent, and an EXIT procedure was avoided.

Gastric heterotopia in the nasopharynx

Heterotopic gastrointestinal mucosa is rare in head and neck area. Most cases are described in oral cavity especially in the floor of the mouth. We present herein the case of an 8-month old infant with a tumor-like mass in the cavum which consisted of an heterotopic gastric mucosa. This case is the first described in this localisation. A brief review of the literature and histopathologic differential diagnoses will be study.
