title: Salivary gland diseases: infections, sialolithiasis and mucoceles.
abstract: The three most frequently diagnosed salivary gland diseases are salivary gland infections, sialolithiasis and mucoceles. Salivary gland infections are usually of bacterial or viral etiology and can be divided into acute and chronic types. Occasionally they can result from obstruction of the salivary duct, an autoimmmune disease or cancer therapy. Infections can occur in all types of salivary glands and are observed at all ages. Sialolithiasis is characterized by the development of calcified structures in the salivary glands, especially in the submandibular gland. Sialoliths are generally attributed to retention of saliva and are usually accompanied by swelling and pain when a salivary stimulus is applied. Mucoceles can be differentiated into mucus extravasation phenomenon or mucus escape reaction, mucus retention cysts and ranulas. They result from extravasation of saliva into the surrounding soft tissues or from retention of saliva within the duct.
