Mucoepidermoid carcinomas (MECs) are the most common malignant tumour of the salivary glands. MECs have also been reported to occur in atypical sites. Primary MECs of the thyroid gland are extremely rare, accounting for 0.5% of thyroid malignancies with approximately 48 cases reported in the literature. In most cases, these are low-grade neoplasms with good long-term prognosis. We present the case of a 74-year-old patient with poorly differentiated MEC of the thyroid gland, which behaved aggressively resulting in rapid decline and death of the patient. The exact pathophysiology of the disease remains unclear and there is no consensus on the optimal treatment for this histological subtype. Recognition and diagnosis of this rare neoplasm are important as this can help guide optimal treatment, although in high-grade poorly differentiated cases, treatment options remain limited.

Introduction There are few reports of injury to the soft palate and retropharynx sustained during intubation with the GlideScope® video laryngoscope. Most reports are of isolated injury to the soft palate. Case History We describe a patient in whom the retropharynx was injured but the extent of the injury was not observed initially. The patient did not suffer severe sequelae from this injury. However, this injury can cause serious sequelae if it is not recognised (eg development of a retropharyngeal abscess). Conclusions We recommend that any patient who sustains injury to the soft palate during intubation (particularly if the endotracheal tube passes through the soft palate) should be reviewed an otolaryngologist before removal of the endotracheal tube.

BackgroundCongenital ranulas seldom occur, with bilateral presentation and prenatal diagnosis reported very rarely. We believe this is the first reported case of a neonate with a antenally diagnosed massive congenital ranula, who went on to develop a non-contiguous contralateral ranula, both contributing to obstruction in a complex paediatric airway.Case reportA female neonate was born to a non-primagravid mother via a planned elective caesarean section due to a lower facial defect and oral cyst. Antenatal aspiration of the pseudocyst was performed under ultrasound guidance with limited success. In the immediate post-natal period a poor airway was observed and the cyst was subsequently marsupialised. With the development of macroglossia secondary to oedema and tongue base collapse the airway was secured through surgical tracheostomy. A subsequent ultrasound scan revealed the presence of a second solitary cystic mass on the contralateral side. After careful excision of the contralateral pseudocyst, tongue function improved, with the resolution of a safe airway which permitted successful decannulation. A planned definitive procedure antenatally did not result in the anticipated improvement in function. However the subsequent development of a second non-contiguous pseudocyst and further surgical management resulted in a safe airway, improved masticator function and the ability to thrive.ConclusionsThe prenatal diagnosis of congenital ranulas have been seldom reported, with no reported cases of contralateral occurrence and airway obstruction from an intraoral ranula. This rare case highlights the need for a well considered contingency plan when surgery is required for a neonatal airway at risk.
