title: Unilateral agenesis of the parotid gland: an unusual entity.
abstract: Agenesis of the parotid gland is extremely rare with only few cases reported in the medical literature. This entity can be important to diagnose as occasionally the normal parotid gland can be mistaken for a tumor due to the facial asymmetry. In this article, we present the case of an isolated unilateral parotid gland agenesis in a young child. The entity is discussed along with important associated conditions that should be ruled out. These include amongst others first and second branchial arch anomalies, as well as the Levy-Hollister or lacrimo-auriculo-dentodigital syndrome.
