A 33-year-old male professional singer presented to his dentist with a rapidly growing
lump on his tongue in October 2019. He was a non-smoker and had no significant medical
or family history. The patient was initially not aware of the presence of the lesion
until he felt that he may have burnt the site with a hot meal. On examination, there
was a 3 × 2 cm circumscribed, firm, broad-based and slightly fixed submucosal lump
on the right posterior dorsal tongue. The lump was covered with normal appearing mucosa
with a prominent network of superficial blood vessels (Figure 1). No mucosal ulceration or other lesions were detected on examination. The patient
did not report any symptoms or loss of function.
