Schwannoma is a benign nerve sheath tumor composed of Schwann cells. Schwannomas originating from ganglia are rare, and schwannomas of the submandibular ganglion or glandular branches have not been reported to date. We present a case of a Japanese woman in her sixties with a submandibular schwannoma originating from the submandibular ganglion, mimicking a submandibular gland tumor on radiological findings. As the radiological findings were nonspecific, the key finding in the present case may be the characteristic location of the tumor suspended from the undersurface of the lingual nerve and situated above the deep portion of the submandibular gland.
