Swelling of the floor of the mouth

      A 22-year-old male with no history of previous surgery or trauma of the oral cavity or neck, presented to our department with a 6-month history of an increasing swelling in the floor of the mouth. The patient did not report any eating or swallowing difficulties, but his elocution was mildly impaired. He had no pain or dyspnoea. Physical examination revealed a large symmetrical, midline, soft, non-tender and non-pulsatile swelling of the floor of the mouth, with normal covering mucosa. There was mild displacement of the tongue superiorly and posteriorly (Figure 1A). A head and neck MRI was performed (Figure 1B).
