title: A first branchial cleft anomaly within the parotid gland.
abstract: Although the parotid glands are affected more frequently by cysts and congenital lesions than other salivary glands, the benign multigerminal cyst arising from a duplication anomaly of the first branchial cleft within the parotid gland is extremely rare. Forty-two cases of this unusual cause of parotid swelling have been reported in the literature. An example of a first branchial cleft anomaly appearing clinically as a parotid tumor is reported.
