title: Parotid gland swelling.
abstract: The salivary glands are seldom noticed by the physician when they are functioning properly, but they cause vexing problems in diagnosis and management during times of their disordered function. One reason for this is that numerous salivary diseases have similar onsets and patterns of symptomatology. Another reason is that the clinical expression of these diseases is often similar, including pain, diffuse swelling, and altered salivary discharge. This paper enumerates useful points of differentiation which may be elicited from the history and physical examination to distinguish among parotid diseases. If management is to be successful, it must be based on (1) identification of the etiology of the pathologic process, and (2) the institution of therapeutic measures designed to eliminate the etiology of the disease, and restore, as closely as possible, the normal physiology of the gland.
