A Case of Basal Cell Adenoma Arising in a First Branchial Cleft Cyst / 대한이비인후과학회지

ABSTRACT

Several types of cyst may occur in the neck. Branchial cleft cyst is the most common cystic lesion, but the first branchial cleft cyst is a very rare disease. Cystic cervical lesions may be mistaken for enlarged lymph nodes or tumors. To avoid interpretation errors, aspiration of all cysts or cystic lesions must be followed by careful palpation and reaspiration of any residual mass. Further, a careful analysis of the patient's clinical data is of value. In questionable cases, surgical excision of the cystic tumor for histologic examination is recommended. We report a case of basal cell adenoma arising in the first branchial cleft cyst. This case support the hypothesis that lymphoepithelial cysts of the major salivary glands arise from inclusions of salivary gland tissue in lymph node.
