Congenital aplasia of the parotid gland with omolateral cheek angioma: case report and review of the literature.

Congenital agenesis of the parotid gland is a rare entity whose etiopathogenesis is still unclear. It is usually bilateral and is sometimes associated with other developmental anomalies of the head and neck region. A case is presented in which aplasia of the right parotid gland was associated with an omolateral angioma of the cheek. The radiological diagnostic approach and a review of the literature on agenesis of the salivary glands are presented.
