Dermoid cyst of lateral neck mimicking a branchial cyst. A case report

ABSTRACT

Dermoids on lateral aspect of neck are very rare. We present a case of benign dermoid cyst on the lateral neck mimicking a branchial cyst. The popular theory of their origin from embryonic rest cells in fusion lines does not explain their location in the lateral neck especially at the junction of upper and middle third neck. We discuss the pathogenesis, radiological findings and review the literature
