title: [Lymphoepithelial cyst of the upper neck: report of a case].
abstract: A case of lymphoepithelial cyst of the upper neck is presented. The patient was a 77-year-old woman. After her lesion was extirpated under clinical diagnosis of salivary gland tumor, identified as lymphoepithelial cyst (so-called branchial cyst). Histopathologically salivary gland was observed in the cyst wall composed of lymphoid tissue and was demonstrated highly active amylase-enzyme (S type) in the cyst fluid. These findings are convicted that our case originates ductal epithelium entrapped in cervical lymph node (inclusion theory of Bhaskar).
