악하선에 발생한 고대 신경초종 1예

Abstract

Ancient schwannoma is a benign neoplasm of nerve origin and may cause difficulties in the differential diagnosis with other benign or malignant tumors. It is also a rare variant of schwannoma with atypical tumor cells with nuclear pleomorphism and hyperchromatism. In this report, a 44-years-old female patient with an ancient schwannoma of the submandibular gland is presented, discussed, and the literature is reviewed for head and neck location of this tumor.
