Boy's 'bluish' lump that lasted for two weeks

A boy has been rushed to the emergency room after a blue mass was found in his mouth.

The boy, 11, noticed it growing for two weeks and it was described as “a progressive, non-painful, swelling mass”, according to the case published in The Annals of Emergency Medicine.

While he wasn’t in pain, it did cause him difficulty eating and swallowing.

“Physical examination revealed a bluish, oval, 2.5x1cm, sublingual mass arising from the mouth floor, which was soft and painless,” researchers wrote.

“Point-of-care ultrasonography performed by the emergency physician revealed the diagnosis.”

The boy was diagnosed with sublingual ranula.

“It is a pseudocystic lesion that occurs usually after an oral trauma or sublingual salivary gland inflammation, which leads to extravasation of the saliva to the mouth floor,” researchers wrote.

“If left untreated, it can cause difficulty in speech and mastication, and even airway obstruction in rare cases.”

Extravasation means fluid leakage into a surrounding area - in this case, fluid from the salivary gland onto the bottom of the boy’s mouth.

It’s not clear what treatment the boy received but he was referred to a specialist to get the issue resolved.

Doctors added sublingual ranulas are “relatively common” in children.
