Oral mucocele in infant with an unusual presentation.

Mucocele is a benign lesion characterised by an extravasation or retention of mucous secretion in submucosal tissue from minor salivary glands. The occurrence of mucocele is common in the oral cavity, with more than 70% of cases on lower labial mucosa. The occurrence of mucocele on the tongue is considered rare and accounted for only 2.25% in the previous literature. Histopathological examination plays a great role in the confirmation of the clinical diagnosis. Management of mucocele is at times challenging. This paper highlights a rare case of mucocele in a 5-month-old infant who was successfully managed under day-care anaesthesia. © BMJ Publishing Group Limited 2020. No commercial re-use.
