This clinical report discusses the presence of a common oral pathology, the mucocele, in an unusual location, the ventral surface of the tongue. These are rare mucoceles associated with the Blandin-Nuhn salivary gland. The likely aetiology, diagnostic features and clinical management and histology are discussed. An 8-year-old male presented at a paediatric practice with a lump under his tongue. A provisional diagnosis of mucocele was made and later confirmed by histology. The lesion was excised completely under local anaesthetic and inhalation sedation.
CPD/Clinical Relevance: A mucocele on the ventral surface of the tongue in a young patient could easily be missed or misdiagnosed.
Article
Derived from two Latin words, mucus and cocele (cavity), mucoceles are the most common lesions found in the oral cavity and the 17th most common salivary gland lesion. They can be found in the oral cavity, appendix, gallbladder, paranasal sinuses and lacrimal sac.
They result from a trauma or alteration to a minor salivary duct causing accumulation of mucus. Based on the histological findings, they can be classified into two types: retention and extravasation. Extravasation type mucoceles are commonly found on the lower lip, and anterior tongue and buccal mucosa, but are rarely on the posterior tongue, palate and retromolar regions, which are more common sites for retention mucoceles. When present on the floor of the mouth they are typically known as ranulas.1
Mucoceles are small blue lesions that are fluctuant on palpation and usually have no associated symptoms. They are most commonly found on the lower lip but can also be found on the cheek, floor of the mouth and tongue.2 When found on the ventral surface of the tongue they are associated with the Blandin–Nuhn salivary gland and are reported as rare, with prevalence being traditionally reported at around 1.9–10.3% of all mucoceles.3,4 A more recent study has suggested they could comprise up to 18.3% of all mucoceles.5
