Abstract:
Schwannomas mostly occur as solitary tumors, and multiple schwannomas are very rare. Schwannomas in the submandibular space are extremely rare. Furthermore, schwannomas in the midline space between the bilateral genioglossus muscles are even rarer. We report multiple schwannomas arising in the midline space between the bilateral genioglossus muscles and left submandibular space. Because the common differential diagnosis of the midline deep sublingual lesions does not include schwannoma for the rarity, surgeons should consider schwannoma in the differential diagnosis.
