ABSTRACT

The schwannoma arises from schwann cell of nerve fibers at various site of body and it is a benign, solitary tumor. About 25 to 35% of total cases occur in the head and neck region. The acoustic shwannoma is the most common in the head and neck area, but the schwannoma arising from vagus nerve is rare.

Retrogressive changes including necrosis, cystic degeneration, lipidization and focal thrombosis are commonly seen in schwannoma. Cystic schwannomas manifest spaces filled with serous fluid or proteinaceous material. The majority of these tumors can completely be removed by simple excision and the prognosis is excellent.

The authors have recently experienced a case of schwannoma of vagus nerve with cystic change in 38-year-old man. The tumor was completely removed by simple excision. We report this case with review of the literatures.
