Schwannomas of the head and neck: a case series.

Schwannomas are relatively slow growing benign tumors of the nerve sheath with a well developed capsule. They can reach a considerable size. Typically, symptoms of schwannomas are based on the affected nerve. We present four cases of this tumor that occurred in the head and neck. The differential diagnosis of small painless nodules in head and neck must include schwannomas as it is likely that nerve sheath neoplasms are more common than previously reported. However, due to benign nature and low recurrence prognosis is excellent.
