[A swelling under the tongue: cyst of the Blandin-Nuhn salivary glands].

Two patients presented themselves with a recurrent swelling under their tongue. The first patient was a 10-year-old boy, whose swelling was enucleated, but recurred after some time. The second patient was an 18-year-old boy, whose swelling had previously been marsupialized. In the second case a MRI was performed, showing a cystic lesion which arose from the Blandin-Nuhn salivary glands. In both patients the lesions were removed under general anaesthesia and in both cases the histopathological findings confirmed this diagnosis; cyst of the Blandin-Nuhn salivary glands.
