Rare salivary gland conditions
November 13, 2018Last month, I discussed surgical approaches to sialoceles. In this month’s column, I’ll tackle rare salivary gland conditions that are treated medically rather than surgically. Let’s start with some definitions. Sialadenosis refers to noninflammatory, nonneoplastic enlargement of the salivary glands, which tends to not be painful. Sialadenitis is inflammation of a salivary gland (synonym: sialoadenitis). Necrotizing sialometaplasia is squamous metaplasia of salivary gland lobules and ducts with ischemic necrosis of the salivary gland lobules (a histopathological distinction).
