Marked bilateral parotid enlargement in metabolic syndrome: a case report and review of the literature.

Bilateral non inflammatory salivary gland enlargement (sialadenosis) is seen with a diverse number of diseases. It is commonly recognized in alcoholism, anorexia and bulimia nervosa and HIV infections. The association between diabetes mellitus and sialadenosis has been reported rarely in the last three decades. We report a patient with sialadenosis in association with metabolic syndrome. We discuss the clinical implications of this novel association including possible regression of salivary gland enlargement with intensive glycemic and lipid control.
